TDSR (Total Debt Servicing Ratio): Your total monthly debt obligations — including the new home loan — must not exceed 55% of your gross monthly income. Applies to all property purchases.
MSR (Mortgage Servicing Ratio): Your monthly HDB or EC loan instalment must not exceed 30% of your gross monthly income. Applies only to HDB flat and new EC purchases.
Both are assessed at the point of loan application, using a stress-test interest rate set by MAS — currently 4.0% p.a. for private property and 3.0% p.a. for HDB loans (floor rates; lenders use whichever is higher).
Variable income (commissions, bonuses) is typically discounted by 30% when computing TDSR/MSR.
Both rules are administered under MAS Notice 645 (for banks) and parallel HDB Board regulations.
Exceeding either limit means the bank cannot grant the loan — regardless of your credit score or property value.
What Are TDSR and MSR? Why Do They Exist?
The Total Debt Servicing Ratio and the Mortgage Servicing Ratio are Singapore’s two primary borrower-level safeguards in the property financing framework. Where measures like ABSD and SSD are transaction taxes designed to moderate demand, TDSR and MSR go deeper — they regulate how much any individual borrower can take on, regardless of the property’s value or the borrower’s wealth.
TDSR was introduced on 29 June 2013 by the Monetary Authority of Singapore (MAS), replacing an earlier and less comprehensive framework. It applies to all property loans — for purchases, refinancing, and equity loans on any residential, commercial, or industrial property. MSR — a tighter, supplementary ratio — applies specifically to loans for HDB flats and Executive Condominiums, reflecting the government’s commitment to keeping public and quasi-public housing genuinely affordable for owner-occupiers.
Together, these two ratios are one of the most powerful levers in Singapore’s financial stability toolkit. For a full picture of the broader cooling-measures context, see our Property Cooling Measures Timeline.
TDSR and MSR — The Framework Explained
Figure 1: TDSR and MSR frameworks side by side — what counts, the applicable cap, and who each applies to. Source: MAS Notice 645 / HDB Board.
TDSR — Total Debt Servicing Ratio (55%)
The TDSR calculation adds up all monthly debt obligations — the proposed new home loan instalment, car loans, student loans, credit card minimum payments, personal loans, and any other outstanding borrowing — and divides the total by the borrower’s gross monthly income. The result must not exceed 55%.
The computation is not quite as simple as it sounds. MAS rules require lenders to apply the following adjustments:
Stress-test rate: The home loan instalment is computed using the higher of the actual loan interest rate or the MAS floor rate (currently 4.0% p.a. for non-HDB residential properties, 3.5% p.a. for the medium-term rate). This means your TDSR-qualifying instalment is calculated on a higher hypothetical rate than the bank’s actual offer rate.
Variable income haircut: If part of your income is variable — commissions, overtime, bonuses, rental income — lenders typically apply a 30% discount. A borrower earning S$8,000 base + S$2,000 monthly commission would have an assessed income of S$8,000 + (S$2,000 × 70%) = S$9,400 for TDSR purposes.
Joint borrowers: Where two or more people take a loan together, the TDSR is assessed on the combined monthly income and combined monthly obligations. This can significantly increase the loan quantum available to a couple.
MSR — Mortgage Servicing Ratio (30%)
MSR applies only when you take a loan to buy an HDB resale flat or a new Executive Condominium (EC) during its initial owner-occupation period. It is an additional, tighter constraint on top of TDSR. Where TDSR considers all debts, MSR focuses only on the monthly instalment of the specific HDB or EC loan in question:
MSR does not apply to private condominiums or landed property — even those on 99-year leasehold land. When buying a private condo, only TDSR applies (plus the standard LTV limits). When buying an HDB flat or new EC, both TDSR and MSR apply; the borrower must satisfy whichever is the more restrictive of the two.
Worked Example — TDSR and MSR in Practice
Mr and Mrs Lim are a Singapore Citizen couple. Mr Lim earns S$7,500/month salary; Mrs Lim earns S$5,500/month. Combined gross income: S$13,000/month. They have a car loan with a monthly instalment of S$1,200.
Scenario A: Buying an S$800,000 HDB resale flat (bank loan)
MSR limit: 30% × S$13,000 = S$3,900/month for the HDB loan instalment.
TDSR limit: 55% × S$13,000 = S$7,150/month for all debts. Less car loan S$1,200 = S$5,950/month available for home loan.
The binding constraint is MSR at S$3,900/month.
Maximum loan at 4.0% stress-test, 25-year tenure: approximately S$741,000.
Scenario B: Buying a S$1.5 million private condo (bank loan, MSR does not apply)
TDSR limit: S$7,150/month for home loan (after car loan S$1,200).
Maximum loan at 4.0% p.a., 25-year tenure: approximately S$1.36 million.
LTV for second property (they still own a first property): 45% → maximum loan S$675,000. LTV is now the binding constraint, not TDSR.
This is why for investors buying second properties, ABSD and LTV often matter more than TDSR.
How TDSR Affects Your Maximum Loan Quantum
Figure 2: Illustrative maximum loan quantum by gross monthly income, assuming no other debts, 25-year loan tenure and 4.0% p.a. stress-test rate. Actual loan amounts depend on credit profile and LTV limits.
The chart illustrates how the 55% TDSR cap translates into loan quantum across different income levels, assuming no other debts. In practice, most borrowers have existing obligations — car loans, credit cards, study loans — that compress the available TDSR headroom and reduce the maximum home loan accordingly.
The Hidden TDSR Trap: Other Debts
Many first-time buyers underestimate how much existing debt erodes their borrowing capacity. Every dollar of existing monthly debt obligation reduces the monthly instalment available for a home loan, which translates into a smaller maximum loan.
Figure 3: How car loans, credit card minimums, and personal loans reduce the maximum home loan for a borrower on S$10,000/month gross income. Stress-test rate 4.0% p.a., 25-year tenure.
A borrower earning S$10,000/month with a car loan of S$1,200/month and credit card minimum payments of S$500/month has only S$3,800/month left for a home loan instalment under the 55% TDSR cap — compared to S$5,500 if they had no other debts. That S$1,700 monthly reduction translates into roughly S$330,000 less in maximum loan quantum at current stress-test rates. This is why financial planners consistently advise property aspirants to pay down or close outstanding credit facilities before applying for a mortgage.
TDSR, MSR and the Loan-to-Value (LTV) Framework
TDSR and MSR cap how much you can service; the Loan-to-Value limits cap how much you can borrow as a proportion of the property value. The two frameworks operate in parallel — both must be satisfied simultaneously. The applicable LTV limit depends on whether you are buying with HDB loan or bank loan, and how many outstanding property loans you have:
Loan Type
1st Property Loan
2nd Property Loan
3rd+ Property Loan
HDB concessionary loan
80% of flat value
N/A (only for 1st HDB purchase)
N/A
Bank loan (no outstanding loans)
75% of property value
45%
35%
Bank loan (1+ outstanding loan)
45%
35%
35%
In practice, it is common for the LTV limit to be the binding constraint when buying investment properties (2nd or 3rd property), while TDSR / MSR is more likely to bite first-time buyers with lower incomes or significant existing debts.
TDSR Exemptions and Special Cases
A small number of situations fall outside the standard TDSR computation:
Bridging loans: Bridging loans used for the express purpose of financing a property being simultaneously sold are treated differently — the outstanding bridging instalment is excluded from TDSR until the property is sold, subject to conditions.
Retirees and elderly borrowers: Banks may use retirement income, CPF LIFE payouts, or annuity income to support TDSR calculations, though the assessment is more complex and requires additional documentation.
Refinancing with no cash-out: From August 2021, MAS allowed certain refinancing transactions — specifically owner-occupier residential loans where no equity is being extracted — to be exempt from TDSR. The borrower must have been servicing the existing loan for at least 12 months and must not be extracting equity.
Why TDSR and MSR Matter for Sellers Too
TDSR and MSR are typically framed as buyer concerns. But sellers are affected too:
Pricing strategy: A seller asking S$1.5 million for a condo needs to consider whether the pool of buyers who can qualify for a S$1.05 million bank loan (70% LTV) under TDSR is large enough to generate competitive offers. A listing price that implies a loan instalment near the TDSR limit for the target buyer profile will attract fewer bidders.
Timing of your own purchase: If you are selling to fund a new purchase, be aware that even after the sale proceeds come in, your TDSR is still assessed on your ongoing monthly income — not on net worth or cash in the bank.
What Might Change?
The TDSR framework has been remarkably stable since 2013, though MAS adjusted the cap from 60% to 55% in December 2021 as part of a broader tightening round. As of May 2026, MAS has not signalled any further changes to TDSR or MSR thresholds. However, MAS publishes annual Financial Stability Reviews (typically in November) which assess household leverage and mortgage risk — these are the best early indicators of possible future adjustments. Read the latest review at mas.gov.sg.
Frequently Asked Questions
What counts as “gross monthly income” for TDSR?
Gross monthly income includes fixed salary, director’s fees, and recognised recurring income. Variable components — commissions, bonuses, overtime — are typically discounted by 30% per MAS guidance. Self-employed individuals use their assessed income from NOA (Notice of Assessment) averaged over 2 years. Rental income is included but also subject to a discount. The bank will determine the applicable figure based on supporting documents submitted at loan application.
Why is my loan computed at a higher rate than the bank’s offer rate?
MAS requires lenders to stress-test all property loans using a minimum floor rate — currently 4.0% p.a. for private residential properties (or the actual rate if higher). This ensures borrowers can still service their loans if interest rates rise after the lock-in period expires. The bank’s actual offer rate (e.g. 3.0% in a low-rate environment) is used for the actual instalment calculation, but the TDSR computation uses the stress-test rate to determine affordability.
Does CPF count as income for TDSR purposes?
No. CPF contributions and balances are not counted as income for TDSR calculations — they are savings, not income. However, using CPF to fund the down payment or monthly instalment does reduce the cash instalment burden, and CPF usage is factored into your overall mortgage planning. The TDSR calculation is based on cash-equivalent gross income per MAS Notice 645.
Does paying off a car loan before applying for a mortgage really help?
Yes, significantly. Each S$1,000 in monthly debt obligations you eliminate frees up S$1,000 in TDSR headroom. At a 4.0% stress-test rate over 25 years, that translates into roughly S$190,000 in additional loan quantum. If you are planning a property purchase in the next 1–2 years, clearing high-instalment debts well in advance is one of the most concrete steps you can take to maximise your borrowing capacity.
I am buying an HDB flat. Do I need to satisfy both TDSR and MSR?
Yes. When taking a bank loan for an HDB resale flat, both TDSR (55%) and MSR (30%) apply. You must satisfy whichever is the more restrictive constraint. In most cases, for HDB buyers, the MSR 30% cap is the binding constraint because it is narrower. If you take an HDB concessionary loan (the HDB loan), the rules are similar but administered by HDB rather than MAS — the MSR cap of 30% still applies.
Can I use a guarantor to get around TDSR?
A guarantor’s income can be included in the TDSR computation only if the guarantor is a co-borrower — i.e. their name is on the loan. If the guarantor is merely guaranteeing repayment without being a borrower, their income cannot be used to support TDSR. Adding a co-borrower is a legitimate approach, but also means the co-borrower’s ABSD property count and LTV position are affected by the loan.
How do TDSR and MSR interact with HDB’s income ceiling for BTO?
HDB’s income ceiling for BTO applications (currently S$14,000/month for couples for most flat types) is a separate eligibility criterion — it determines whether you can apply for a BTO flat, not how much you can borrow. TDSR and MSR determine the loan quantum once you are eligible. A couple earning S$14,000 may pass the HDB income ceiling but still be limited in their borrowing by TDSR/MSR, particularly if they have significant existing debt obligations.
This article is for general informational purposes only and does not constitute financial, legal, or mortgage advice. TDSR and MSR rules are administered by the Monetary Authority of Singapore under MAS Notice 645 and MAS Notice 645A, and by HDB under its loan policies — these are subject to change.

Always consult a licensed mortgage broker or financial adviser, and verify the current rules directly at mas.gov.sg and hdb.gov.sg before making any borrowing decisions.
Singapore home loans are now primarily benchmarked to SORA (Singapore Overnight Rate Average) — the official replacement for SIBOR, which was phased out in December 2024.
As at May 2026, the 3-month compounded SORA is approximately 2.55%, down from its 2023 peak of above 3.7%.
Major banks offer two main packages: SORA-pegged floating rates (typically SORA + 0.85–0.90%) and fixed rates (typically 2.45–2.65% for a 2-year fixed term).
The HDB Concessionary Loan is pegged at CPF OA + 0.1%, currently 2.60%; it is available only for HDB flats and requires no lock-in period.
The Total Debt Servicing Ratio (TDSR) cap of 55% and Mortgage Servicing Ratio (MSR) cap of 30% remain in force and directly limit how much you can borrow.
Fixed rates offer payment certainty but come with a lock-in penalty (typically 1.5% of outstanding loan) if you refinance early.
SORA-pegged loans offer transparency and flexibility, but your repayment will move with rates — currently favourable as SORA trends down from its 2023 highs.
Understanding Singapore Home Loan Interest Rates in 2026
When you take out a home loan in Singapore, the single most consequential variable is the interest rate. On a S$1 million loan over 25 years, the difference between a 2.45% and a 3.40% rate translates to roughly S$470 more per month — or over S$140,000 in additional interest over the life of the loan. Yet many buyers in Singapore choose their home loan based on convenience, the advice of a mortgage broker with a vested interest, or simply whatever their bank’s relationship manager recommends at point of sale.
This guide explains how Singapore home loan interest rates are structured in 2026, what SORA is and why it replaced SIBOR and SOR, how to read bank package offers correctly, and how to decide between a floating rate and a fixed rate package given the current interest rate environment. It is written for Singaporean and Permanent Resident property buyers — the same principles apply to foreigners but their ABSD liability fundamentally alters the financing calculus.
Monetary Authority of Singapore (MAS) regulates home lending in Singapore under the Monetary Authority of Singapore Act and the Notice MAS 632 on Residential Property Loans. HDB administers the Concessionary Loan under the Housing and Development Act.
Figure 1: SORA 3-Month Compounded Average vs 2-year Fixed Rate — Major Singapore Banks, 2020–2026. Data: MAS, bank publications.
What Is SORA and Why Did It Replace SIBOR?
SORA — the Singapore Overnight Rate Average — is the volume-weighted average rate of all overnight unsecured Singapore dollar interbank transactions brokered in Singapore between 08:00 and 18:15 each business day. It is published daily by MAS and is calculated retrospectively, which makes it a backward-looking, transaction-based benchmark rather than a quote-based one like SIBOR was.
SIBOR (Singapore Interbank Offered Rate) was phased out on 31 December 2024 following a global reform of interest rate benchmarks prompted by the 2012 LIBOR manipulation scandal. SOR (Swap Offer Rate), which was partly based on USD LIBOR, was discontinued even earlier. MAS and the Steering Committee for SOR & SIBOR Transition to SORA (SC-STS) oversaw the transition, which required all existing SIBOR-pegged mortgages to be converted to SORA-linked packages by end-2024.
SORA is now used in three primary forms for home loans:
1-Month Compounded SORA (1M SORA) — reflects the past 30 days of overnight rates. More reactive to short-term rate changes.
3-Month Compounded SORA (3M SORA) — reflects the past 90 days. More commonly used by banks for home loans; provides a slightly smoother signal.
SORA Board Rates — some banks (notably UOB) have internal board rates that are partially informed by SORA movements but give the bank more discretion over repricing.
SORA-Pegged Floating Rate Packages
A SORA-pegged floating rate package ties your home loan to the prevailing 3M Compounded SORA, plus a fixed spread set by the bank. As at May 2026, spreads across major banks range from +0.85% to +0.90%:
DBS: 3M Compounded SORA + 0.85%
OCBC: 3M Compounded SORA + 0.88%
UOB: 3M Compounded SORA + 0.90%
Maybank: 3M Compounded SORA + 0.85%
With 3M SORA at approximately 2.55% in May 2026, an all-in floating rate works out to roughly 3.40–3.45%. This is broadly similar to the prevailing 2-year fixed rate, which sits at 2.45–2.65% for Year 1–2 before typically reverting to a board rate or SORA-linked rate from Year 3.
The key characteristics of a SORA floating package are:
No lock-in period — you can refinance or reprice at any time without a penalty clause.
Transparent repricing — your rate changes as SORA moves, typically with a 1-month lag for 1M SORA packages or a 3-month lag for 3M packages.
Currently in a declining environment — if MAS and the Federal Reserve continue rate normalisation through 2026, SORA is expected to drift toward 2.2–2.4% by end-2026, which would bring all-in floating rates to around 3.05–3.30%.
Figure 2: Singapore Home Loan Package Comparison — DBS, OCBC, UOB, HDB Concessionary Loan and others, May 2026. Rates indicative; verify with lender.
Fixed Rate Packages
Fixed rate packages lock in an interest rate for a specified period — typically 2 years — after which the loan reverts to a floating rate, usually SORA-linked or a bank board rate. As at May 2026, major banks are offering:
Bank
Year 1
Year 2
Year 3+
Lock-in
DBS
2.45%
2.55%
FHR8 (board rate)
2 years
OCBC
2.50%
2.60%
OHR+ (SORA-linked)

UOB
2.45%

SORA + spread
2 years
Standard Chartered
2.48%
2.60%
Board rate
2 years
Maybank
2.50%
2.65%
SORA + spread
2 years
The 2-year fixed period provides payment certainty — you know exactly what you will pay every month for the fixed term, which makes household budgeting straightforward. The risk is that if you need to refinance during the lock-in window — for example, because you sell the property, or a better package becomes available — you will typically pay a penalty of 1.50% of the outstanding loan amount at the time of early redemption.
On a S$1 million loan, that penalty is S$15,000. This is not an insignificant sum, and it is the primary reason experienced property investors often prefer no-lock-in floating packages despite the slightly higher all-in rate today.
The HDB Concessionary Loan — A Third Option
Buyers purchasing an HDB flat have access to a third option: the HDB Concessionary Loan, currently at a flat 2.60% per annum. This rate is set at CPF Ordinary Account interest rate (currently 2.5%) plus 0.1%, and is reviewed quarterly. It has remained at 2.60% since January 2023 when the CPF OA rate was last adjusted.
The HDB Concessionary Loan is notable for several reasons:
No lock-in — you can switch to a bank loan at any time without penalty.
LTV up to 80% — the maximum Loan-to-Value for an HDB loan is 80% of the purchase price or valuation (whichever is lower), versus 75% for a bank loan.
No cash down payment requirement — the 20% down payment can be funded entirely from CPF Ordinary Account (unlike bank loans, which require at least 5% in cash).
Eligibility conditions — all owners must not own any other residential property; income ceiling of S$14,000 household income applies for most flat types (no ceiling for HDB resale). You must obtain an HDB Flat Eligibility (HFE) Letter before exercising an OTP.
TDSR and MSR — How Much Can You Borrow?
MAS introduced the Total Debt Servicing Ratio (TDSR) framework in June 2013 to ensure borrowers do not over-leverage. TDSR limits total monthly debt obligations (including the new mortgage, car loans, personal loans, credit card minimum payments and all other credit facilities) to 55% of gross monthly income. Banks apply a stress-test rate of 4.0% per annum when assessing TDSR — meaning they calculate your hypothetical monthly payment at 4.0% regardless of the prevailing rate, to ensure you can afford the loan even if rates rise.
For HDB flat purchases (both BTO and resale), the additional Mortgage Servicing Ratio (MSR) cap applies: your monthly mortgage payment must not exceed 30% of gross monthly income. MSR applies to the actual servicing payment, not a stress-tested figure.
These rules mean that on a gross household income of S$10,000 per month, the maximum monthly mortgage payment you can qualify for (under MSR for HDB) is S$3,000; and the maximum all-debt obligation under TDSR is S$5,500. Practically, if you have a car loan of S$800/month, your maximum mortgage under TDSR is reduced to S$4,700/month.
Figure 3: Monthly Repayment by Rate Scenario — S$1M Loan, 25-Year Tenure. Illustrative; based on standard annuity formula.
Worked Example — The Tan Family’s Loan Decision
Mr and Mrs Tan are Singapore Citizens purchasing a S$1.4 million OCR condominium in Tampines in June 2026. They are first-time buyers with no outstanding home loans. Their gross combined household income is S$14,000 per month. They have S$180,000 in CPF OA (combined) and S$100,000 in cash savings.
Loan quantum: 75% LTV on S$1.4M = S$1.05M bank loan. Down payment = S$350,000 (25%), of which at least S$70,000 (5%) must be in cash. The Tans comfortably clear this with S$70,000 cash + S$280,000 CPF.
BSD: S$24,600 on S$1.4M (first S$180k at 1%, next S$180k at 2%, next S$640k at 3%, remaining S$400k at 4% — total S$1,800 + S$3,600 + S$19,200 = wait, let me compute correctly: BSD on S$1.4M = 1%×S$180k + 2%×S$180k + 3%×S$640k + 4%×S$400k = S$1,800 + S$3,600 + S$19,200 + S$16,000 = S$40,600). ABSD: S$0 (first purchase, SC).
Rate comparison:
Option A — 2-year fixed at 2.45%/2.55%: Monthly in Year 1 = S$4,634; Year 2 = S$4,706. Reverts to SORA + spread from Year 3 (est. ~S$4,500–4,800 depending on SORA trajectory). Lock-in penalty if exit before 24 months: ~S$15,750 (1.5% × S$1.05M).
Option B — SORA float at SORA+0.85% ≈ 3.40%: Monthly = ~S$5,161. No lock-in. If SORA falls to 2.2% by end-2026, rate drops to ~3.05%, monthly ~S$4,956.
Option C — If they were buying an HDB resale (for illustration): HDB Concessionary Loan at 2.60% → monthly ~S$4,748 on S$1.05M, 80% LTV available.
TDSR check (Option A, Year 1): Monthly payment S$4,634. With no other debts, TDSR = S$4,634 ÷ S$14,000 = 33.1%. Well within 55%. Stress-tested at 4.0%: hypothetical monthly = S$5,534; TDSR = 39.5%. PASS.
Recommendation: Given the declining SORA environment in 2026, the Tans opt for Option A (2-year fixed) to lock in payment certainty during the early years of ownership when their cash position is most stretched. They set a calendar reminder to review and refinance in Month 20, before the lock-in expiry.
Fixed vs Floating — How to Decide in 2026
With fixed and floating rates now converging at around 3.35–3.50% all-in, the classic argument — “floating is cheaper, fixed is certain” — no longer cleanly applies. The decision framework for 2026 hinges on three questions:
How long will you hold the property? If you plan to sell within 3 years (e.g., you are buying a resale flat as a stepping stone and expect to MOP a BTO), a floating package with no lock-in avoids the exit penalty. If you plan to hold for 10+ years, the 2-year fixed-then-float cycle is largely a moot point — both packages will track the same rates over the long run.
How sensitive is your monthly budget to rate moves? If a S$300–500 increase in monthly repayment would significantly stress your household, a fixed rate gives you a planning buffer. If you have comfortable headroom under TDSR, floating is fine.
What is the SORA outlook? As at May 2026, MAS and market consensus lean toward SORA continuing a gradual decline through 2026–2027 as the global rate cycle normalises. In a declining rate environment, locking in at today’s fixed rate means you may pay slightly more than the eventual SORA level. However, the gap is likely to be narrow (0.10–0.30%) and the certainty premium may be worth it for first-time buyers.
What Might Come Next — Singapore Loan Rate Outlook
Several factors will shape Singapore home loan rates through end-2026 and into 2027. MAS operates a unique monetary policy framework — it manages the Singapore dollar nominal effective exchange rate (S$NEER) rather than directly setting an overnight rate, meaning SORA is market-determined rather than policy-set. However, SORA is strongly correlated to the US federal funds rate through Singapore’s open capital account.
The US Federal Reserve has signalled two 25-basis-point cuts in the second half of 2026, which, if executed, would likely push 3M SORA from ~2.55% toward ~2.05–2.15% by year-end. This would bring SORA-pegged all-in rates to around 2.90–3.05% — meaningfully below today’s fixed rates of 2.45–2.65% over a 2-year view. Whether banks adjust their fixed rate offerings in anticipation remains to be seen; historically, fixed rates tend to reprice down with a 1–2 quarter lag.

Frequently Asked Questions
What is SORA and how is it different from SIBOR?
SORA (Singapore Overnight Rate Average) is the volume-weighted average of unsecured overnight interbank SGD transactions, published daily by MAS. SIBOR was a forward-looking rate based on bank submissions — susceptible to manipulation, as the 2012 LIBOR scandal revealed globally. SORA is transaction-based and backward-looking, making it more robust and harder to manipulate. SIBOR was fully discontinued on 31 December 2024; all SIBOR-pegged mortgages were converted to SORA or fixed-rate packages during 2023–2024.
Should I choose a fixed or floating rate home loan in 2026?
With SORA declining toward 2.2% by end-2026 and fixed rates at 2.45–2.65%, the all-in rates are converging. For first-time buyers who need budgeting certainty, a 2-year fixed rate is sensible — it protects against any short-term rate surprise and costs only marginally more than today’s floating all-in rate. For investors and experienced buyers who plan to hold long-term or who may sell within 3 years, a no-lock-in SORA floating package avoids exit penalties and will benefit as SORA falls further. In 2026 specifically, the edge is modest either way; the bigger decision is the property itself.
What is the current SORA rate in 2026?
As at May 2026, the 3-month compounded SORA is approximately 2.55% per annum, down from its peak of above 3.74% in mid-2023. It has been declining steadily as the US Federal Reserve began its rate normalisation cycle in late 2024. MAS publishes daily SORA rates on its website at mas.gov.sg/monetary-policy/sora.
What is TDSR and how does it affect how much I can borrow?
The Total Debt Servicing Ratio (TDSR) limits your total monthly debt obligations (including the home loan, car loans, personal loans and other credit facilities) to 55% of your gross monthly income. Banks stress-test your loan at 4.0% per annum when assessing TDSR eligibility — so even if the prevailing rate is 3.0%, the bank calculates whether you could afford the repayment at 4.0%. On top of TDSR, if you are buying an HDB flat, the Mortgage Servicing Ratio (MSR) limits your monthly home loan repayment to 30% of gross monthly income.
Can I use CPF to pay my home loan?
Yes. CPF Ordinary Account savings can be used to service monthly home loan repayments for both HDB flats and private properties, subject to the Valuation Limit (generally the lower of the purchase price or valuation) and the Withdrawal Limit (up to 120% of the Valuation Limit for private properties). Note that CPF monies withdrawn for property earn accrued interest at 2.5% per annum, which must be returned to your CPF account upon sale. This accrued interest does not represent an additional out-of-pocket cost but reduces the net cash proceeds you receive when you sell.
What is a lock-in period and what happens if I break it?
A lock-in period is a contractual commitment to maintain your loan with the same bank for a set duration — typically 2 years for fixed rate packages. If you refinance, prepay or redeem the loan in full before the lock-in expires, you pay a penalty usually equal to 1.5% of the outstanding loan amount at the time of early redemption. On a S$900,000 outstanding balance, that is S$13,500. No-lock-in packages (all SORA floating packages and HDB Concessionary Loans) allow you to exit or refinance at any time without penalty.
What is the difference between refinancing and repricing?
Repricing is when you switch to a different loan package within the same bank — typically cheaper (no legal or valuation fees) but limited to that bank’s available packages. Refinancing is when you move your loan to a different bank entirely. Refinancing typically offers access to sharper rates but incurs legal fees (S$2,000–3,500), valuation fees (S$300–800), and potentially a clawback of cashback incentives if you refinance within the clawback period (usually 3 years). Both options are typically considered when a fixed rate lock-in expires.

Loan-to-Value (LTV) is the single most important number in a Singapore home-purchase budget. It tells you, before anything else, the maximum slice of the property price the bank is willing to lend — and therefore the cash and CPF you need to bring yourself. Misread it by even five percentage points and you may find yourself short by tens of thousands of dollars on completion day.
This guide walks you through the LTV framework as it stands in 2026 — the rate ladder by housing-loan count, how tenure and age cut into the cap, how LTV interacts with TDSR and MSR, and the practical decisions buyers face. The framework is set by the Monetary Authority of Singapore (MAS) Notice 645 and reinforced by HDB’s own concessionary loan rules.
Quick Answer — LTV at a glance
Bank loan, first housing loan: up to 75% LTV, tenure up to 30 years for private (25 years for HDB).
Second housing loan: up to 45% LTV; third or more: up to 35%.
If tenure exceeds 30 years OR runs past borrower age 65: caps drop to 55% / 25% / 15%.
HDB Concessionary loan: up to 75% LTV, 25-year max tenure.
The cash component of the down-payment is at least 5% (private) or 10% (HDB Concessionary).
LTV is one of three gates — you must also pass TDSR (55%) and, for HDB/EC, MSR (30%).
What Is Loan-to-Value — and Why Does It Exist?
LTV is the ratio of the housing loan amount to the property’s purchase price or market value, whichever is lower. Banks use it as a first-pass risk control: a higher LTV means thinner equity from the borrower, which means less cushion if property prices fall.
MAS sets the LTV ceiling industry-wide. The ceiling has been progressively tightened since the cooling-measure era began in 2013, as the regulator’s priority shifted from supporting first-time owner-occupiers to discouraging investment-driven leverage. The most recent recalibration was December 2021, which lowered LTV on second housing loans from 50% to 45% and on third loans from 40% to 35%. That framework remains in force in 2026.
LTV limits Singapore 2026 — the cap that sets the size of your loan.
The 2026 LTV Ladder — Bank Housing Loans
The headline number you have heard — “75% LTV” — only applies to first-time housing-loan borrowers under standard tenure. Once you have an existing housing loan or stretch the tenure beyond the conservative limit, the cap falls sharply.
Figure 1: LTV ladder for bank housing loans, by housing-loan count and tenure.
Borrower scenario
Standard LTV
If tenure > 30 yrs OR runs past age 65
No outstanding housing loan
75%
55%
One outstanding housing loan
45%
25%
Two or more outstanding loans
35%
15%
Two practical points are worth flagging. First, the 30-year tenure rule does not mean a 30-year loan is always available — banks themselves often cap tenure earlier for older borrowers. Second, the “outstanding housing loan” count includes loans for properties you co-own as a guarantor or as a second name on the title; the regulator does not look only at your primary mortgage.
Cash Component — The Mandatory Minimum
LTV defines the maximum the bank will lend; the rest must come from the buyer. But of that “rest”, a minimum portion must be in cash and cannot be funded from CPF Ordinary Account.
Loan type
Minimum cash
Balance from CPF or cash
Bank loan, 75% LTV
5% of price
20% of price
Bank loan, 55% LTV (long tenure)
10% of price
35% of price
Bank loan, 45% LTV (2nd loan)
25% of price
30% of price
HDB Concessionary loan
10% of price
15% of price (CPF or cash)
The cash floor is the practical constraint that catches most upgraders by surprise. A buyer with a S$1.5M target and 75% LTV needs S$75,000 cash on the table at exercise day — on top of BSD, ABSD, and legal fees. CPF Ordinary Account balances cannot substitute for this minimum.
The Three Gates — LTV, TDSR, and MSR
LTV is only one of three caps. Banks must also satisfy:
Figure 2: The three gates — your loan is the smallest of the three answers.
LTV — absolute % of property value, set by MAS as above.
TDSR (Total Debt Servicing Ratio) — total monthly debt repayments capped at 55% of gross monthly income, stress-tested against a 4.0% medium-term interest rate even though current bank rates are well below that. All debts count: home loans, car loans, education loans, personal loans, credit-card minimum repayments.
MSR (Mortgage Servicing Ratio) — only for HDB flats and Executive Condos within MOP, capped at 30% of gross monthly income.
The bank computes the maximum loan under each rule and lends you the smaller of the three. A buyer at 75% LTV but with a heavy car loan can find their actual loan capped by TDSR rather than LTV; an HDB buyer with no other debts often finds MSR — not LTV — is the binding constraint.
Worked Example — Three Buyer Profiles, Three Loan Sizes
Consider three buyers all looking at the same S$1.5M private condo, taking a 30-year loan at 2.85% fixed:
Figure 3: Three buyer profiles compared on identical S$1.5M condo.
The first-time buyer at age 35, salary S$10k/month, no other loans, gets the textbook 75% LTV: S$1,125,000 loan, S$375,000 down (5% cash + 20% CPF/cash). Monthly payment S$4,663 — comfortably inside 55% of S$10k.
The second-property buyer at age 48 with one outstanding home loan is capped at 45% LTV: S$675,000 loan only, S$825,000 down. This buyer also pays 20% ABSD on the new property — an additional S$300,000.
The upgrader to a tenure that runs past age 65 at age 50 is capped at 55% LTV (because the 30-year tenure runs to age 80, well past 65): S$825,000 loan only. Same income as the second buyer, but bigger loan because no existing housing loan; still smaller than the first-time buyer because of the tenure rule.
HDB Concessionary Loan — A Different Beast
The HDB Concessionary loan, available to buyers of new and resale HDB flats meeting income and ownership criteria, runs on its own framework:
LTV: up to 75% of valuation, identical to first-time bank loan.
Tenure cap: 25 years for new flats, 25 or 30 years for resale depending on age.
Interest rate: pegged to CPF Ordinary Account rate plus 0.1% — currently 2.60% (CPF OA at 2.5% + 0.1% spread, rate-locked).
MSR-only gate: 30% of gross income, no separate TDSR overlay.
Rule of two: Singapore households are limited to two HDB Concessionary loans across a lifetime, with a five-year wait between the first and second.
For comparable risk profiles, the Concessionary loan typically beats bank loans on cost; the trade-off is the more rigid tenure cap and the requirement to deplete CPF OA balances above S$20,000 first.
What This Means for You as a Buyer in 2026
The 2026 environment is the tightest LTV regime Singapore has had in two decades. Combined with stress-tested TDSR at 4.0% and ABSD at 20% on second properties for citizens, the effective leverage available to a typical buyer is materially below where it sat pre-2018.
Three practical conclusions:
Plan around the binding gate, not around LTV alone. Run all three checks before committing — ask your banker to model TDSR with all your debts, and MSR if you are buying HDB or EC.
Tenure is now a real lever for older buyers. Choosing a 25-year tenure that ends before 65 can keep you on the 75% LTV track even at age 40. Stretching to 30 years past 65 cuts to 55%.
Reserve capital, not just cash. The 5% mandatory-cash floor is the headline; in practice you also need BSD, ABSD, legal fees, and a six-month reserve buffer. A S$1.5M purchase typically requires S$120,000 in cash on the table at exercise.
Frequently Asked Questions
Is LTV calculated on the purchase price or the valuation?
The lower of the two. If a property is bought at S$1.5M but the valuation is S$1.45M, the bank applies LTV to S$1.45M. The remaining S$50,000 must be covered in cash — this is the dreaded “valuation gap” that catches buyers in rising markets.
Does selling my existing property before buying a new one reset my LTV count?
Yes — provided the existing housing loan is fully discharged before the OTP date on the new purchase. Banks check the credit bureau records on the day of credit assessment, and a discharged loan no longer counts as outstanding. This is why “sell-then-buy” buyers can access the 75% LTV track that “buy-then-sell” buyers cannot.
Can I take a 35-year loan if I am only 30 years old?
The MAS framework permits it, but bank policies vary. Most banks prefer to cap tenure at 30 years even for young borrowers. Even where 35 years is permitted, the over-30 tenure rule kicks in and reduces the LTV cap to 55% on the first loan — usually a poor trade-off.
Does my spouse’s housing loan affect my LTV count?
If you co-borrow on a single property, you are counted as one applicant for LTV purposes. If your spouse has a separate property in their sole name with an outstanding loan, that does not count against you when you buy in your sole name — this is the basis of decoupling strategies that release ABSD allowance.
What happens if my loan application is approved but my income drops before completion?
Banks reserve the right to re-underwrite at completion. A material income drop (typically more than 20%) between approval and completion can lead to a loan reduction or, in extreme cases, withdrawal. Buyers facing this should engage their banker proactively rather than wait for completion day.
Are there any loans that bypass LTV?
Not for residential property. Some private banks offer “lombard” or asset-backed lending against shares, bonds, or insurance policies, which sit outside the housing-loan framework, but these are not housing loans and the security is the financial portfolio, not the property. They are an option mainly for high-net-worth borrowers with substantial liquid investments.
Does SORA-pegged versus fixed-rate make a difference to LTV?
No. LTV is set by the housing-loan count and tenure, regardless of the rate type. Fixed and floating loans face the same LTV cap. Choice between fixed and SORA is a separate decision driven by rate outlook and personal risk preference.
This article provides general information about LTV and related housing-loan rules in Singapore as at May 2026. It is not financial, tax, or legal advice. LTV ceilings, cash-component rules, TDSR and MSR are set by the Monetary Authority of Singapore, the Inland Revenue Authority of Singapore, and the Housing & Development Board, and may be amended at any time.

Before signing an Option to Purchase, engage a licensed Singapore mortgage banker, conveyancing solicitor, and where relevant a financial planner to model your situation specifically.
Figure 1: The two numbers that decide every Singapore home loan — TDSR at 55% of income and MSR at 30% for HDB and EC purchases.
If you have ever wondered why the bank’s pre-approval letter gave you a smaller loan than you budgeted for — or why a friend on the same salary can borrow noticeably more than you — the answer almost always comes down to two acronyms: TDSR and MSR. These are the two borrowing limits the Monetary Authority of Singapore (MAS) bakes into every residential mortgage, and in 2026 they are the single biggest determinants of how much home you can actually finance.
This guide is the 2026 edition. It covers exactly how TDSR and MSR are calculated, how they interact with the loan-to-value (LTV) cap, where the 4.0% stress-test rate comes from, what counts as income, what doesn’t, and — crucially — how to game the numbers in your favour without breaking any rules. We walk through a fully-worked Singapore example end-to-end and finish with the policy trajectory so you know what to watch for next.
Quick Answer: The 10 Things Every Singapore Borrower Should Know
TDSR is 55%. Total monthly debt repayments — including the new mortgage — cannot exceed 55% of your gross monthly income. Applies to every residential property loan.
MSR is 30%. Mortgage repayments on an HDB flat or Executive Condominium (EC) bought from the developer cannot exceed 30% of gross monthly income. Private condos and landed property have no MSR.
Stress-test rate is 4.0%. TDSR and MSR are calculated at a medium-term interest rate of 4.0% for residential loans, regardless of the rate you actually pay today.
LTV caps layer on top. First housing loan: up to 75% of purchase price. Second housing loan: up to 45%. Third and beyond: up to 35%.
Age and tenure matter. If the loan tenure pushes past age 65, or exceeds 30 years (25 for HDB), the LTV cap drops by 20 percentage points.
Variable income is haircut by 30%. Commission, bonus, rental and freelance earnings are only counted at 70% of the proven figure.
Existing debts eat into headroom. Car loans, credit-card minimum payments, student loans, and other mortgages all hit your TDSR ceiling before the new home loan does.
Guarantors are counted too. If you guarantee a sibling’s loan, it may sit in your TDSR — not theirs.
Cash down-payment rules mirror LTV. The first 5% (25% at higher LTV tiers) must be paid in cash; the balance can be CPF Ordinary Account funds.
Refinancing carve-out. Borrowers refinancing an owner-occupied property with no cash-out may be exempted from TDSR — a narrow but useful escape hatch.
What Is TDSR — The Framework That Underpins Every Home Loan
The Total Debt Servicing Ratio was introduced in June 2013 as part of MAS’s cooling-measures programme (see our full cooling measures timeline for the wider context). Its purpose is simple: to stop households from levering up to a level where a modest rise in interest rates would push them into negative cash flow. The 2010s saw Singapore’s household debt-to-GDP ratio climb past 70%, and MAS wanted a circuit-breaker that worked the same way regardless of which bank a buyer walked into.
TDSR caps all monthly debt obligations at 55% of gross monthly income. “All debt” is deliberately broad: it includes the prospective home-loan instalment (calculated at the stress-test rate), existing mortgages, car loans, personal loans, renovation loans, student loans, credit-card minimum repayments and any loans you have personally guaranteed. Even a dormant credit card with a S$20,000 limit is counted if the bank uses the 3% minimum-payment convention.
The ratio was originally set at 60% in 2013 and tightened to 55% in December 2021, where it remains in 2026. That three-percentage-point shave looks small on paper but at a typical Singapore household income removes roughly S$150,000–S$200,000 of borrowing capacity.
What Is MSR — The Second Ratio You Cannot Ignore for HDB and EC Buyers
The Mortgage Servicing Ratio is narrower but stricter. Introduced for HDB loans in 2011 and extended to bank loans on HDB flats in 2013, MSR caps the mortgage portion alone at 30% of gross monthly income for purchases of HDB flats and Executive Condominiums bought directly from the developer.
MSR is a subset of TDSR, not a substitute. HDB and new-EC buyers must clear both ratios — the tighter of the two binds. In practice MSR is almost always the binding constraint for HDB buyers because existing debt rarely adds up to the 25-percentage-point gap between MSR (30%) and TDSR (55%). For EC buyers the numbers narrow as the project moves through its 10-year maturation period — after the five-year minimum occupation period and the ten-year privatisation, a resale EC is treated like a private condo for borrowing-limit purposes, so TDSR alone applies.
For a side-by-side look at which ratios hit which property type, the matrix below summarises 2026 rules.
Figure 2: 2026 borrowing limits by property type. HDB flats and ECs face both MSR and TDSR; private condos, landed property and commercial assets only face TDSR.
How the 4.0% Stress-Test Rate Works — And Why It Matters More Than Your Actual Rate
Here is the trap that catches most first-time buyers: banks must calculate your monthly instalment using an assumed rate of 4.0% for residential mortgages, even if your actual rate is 2.5% or 3.0%. This is the medium-term interest rate, set by MAS and reviewed from time to time. It was revised upward from 3.5% to 4.0% in September 2022 and has not moved since.
Why 4.0%? The rate is designed to approximate the long-run average that Singapore floating-rate loans have oscillated around over a 30-year horizon. It is deliberately punitive — regulators would rather have borrowers told “you qualify for less” at origination than have the same borrowers go into arrears when rates spike. Anyone who lived through the 2022–2023 rate cycle, when three-month SORA went from 0.2% to 3.8% in 18 months, will appreciate the logic.
The mechanic: the bank plugs a 4.0% rate into the standard amortisation formula using your chosen loan tenure, derives an assumed monthly instalment, and tests that figure against your TDSR (55%) and, if applicable, MSR (30%). Your actual repayment — calculated at whatever rate the bank is offering — will be lower in most cases, leaving you with a margin of safety that MAS consciously engineered.
What Counts as Income — And Why Variable Pay Is Penalised
Income for TDSR/MSR purposes is not what you see on your IRAS tax statement. MAS prescribes a structured treatment:
Fixed salary. Counted at 100%. Evidenced by payslips (usually three to six months) and the latest CPF contribution history.
Variable income. Commission, bonus, overtime, and freelance earnings are haircut by 30%, so only 70% of the verified average is recognised. The haircut applies to the entire variable component, even if you can show multiple years of steady track record.
Rental income. Counted at 70% of the gross rent receivable, net of void periods. A two-year tenancy agreement is strong evidence; month-to-month leases are viewed more sceptically.
Self-employed / business income. Two years of Notice of Assessment (NOA) are the default evidentiary bar, with the 30% haircut applied.
Allowances and AWS. Typically 100% if contractual and evidenced; otherwise haircut.
This is where the seemingly simple 55% number becomes surprisingly individual. A banker earning S$12,000 monthly but with 40% of that as variable gets assessed on S$7,200 fixed + S$3,360 post-haircut variable = S$10,560 — so the TDSR ceiling drops to S$5,808 per month rather than the nominal S$6,600.
What Counts as Debt — The Items Borrowers Miss
The other half of the equation is debt. The headline items — the new home loan instalment, existing mortgages, and car loans — are obvious. Less obvious items often catch borrowers out:
Credit-card minimum payments. Banks use a 3% minimum convention on the outstanding balance (or sometimes on the total credit limit). If you carry S$30,000 revolving credit across cards, that is a S$900 monthly hit on your TDSR — shaving S$192,000 off your loan ceiling at a 4.0% stress rate over 30 years.
Renovation and personal loans. Unsecured loan instalments count in full.
Student loans. Included in TDSR from the date repayments begin.
Guarantor obligations. If you have co-signed a relative’s loan and there is no formal debt-transfer, some banks will count the full instalment against you. Others use 50%. Ask the relationship manager explicitly.
Outstanding ABSD remission obligations. If you are on a remission schedule (e.g. from selling a prior property to claim remission on a new purchase), the existing loan remains in TDSR until the sale completes.
A Fully-Worked Example: A S$10,000-a-Month Household Buying a Private Condo
Figure 3: How different existing-debt profiles crater the monthly headroom available for a new mortgage, given a household earning S$10,000 gross.
Consider a dual-income couple: combined gross monthly salary S$10,000, both on fixed pay, no variable component. They are looking at a S$1.8 million resale private condo in District 15.
Step 1 — TDSR cap. 55% × S$10,000 = S$5,500. No MSR applies because this is a private condo.
Step 2 — Existing debts. One car loan at S$800/month and revolving credit balances generating a S$300/month minimum payment. Total existing obligations: S$1,100.
Step 3 — Headroom for the new mortgage. S$5,500 − S$1,100 = S$4,400 per month available for the new home loan instalment.
Step 4 — Maximum loan principal. At the 4.0% stress rate over a 30-year tenure, S$4,400 monthly funds approximately S$922,000 of loan principal (standard amortisation formula: P = M × [(1 − (1 + r)^(−n)) / r]).
Step 5 — LTV cap. At 75% LTV on an S$1.8m purchase, the bank could lend up to S$1,350,000 — but TDSR limits them to S$922,000 here, so TDSR binds, not LTV. The couple needs S$878,000 of combined cash and CPF equity.
Flip the same household to an HDB flat at S$700,000: now MSR binds first. 30% × S$10,000 = S$3,000 maximum mortgage instalment. That fundamentally funds roughly S$628,000 — well below the 75% LTV ceiling of S$525,000… wait. In this case the 75% LTV actually binds below MSR, because S$525,000 of loan needs only about S$2,500/month at 4.0% over 25 years, comfortably inside MSR. So the couple’s CPF-plus-cash needs to fill the remaining S$175,000.
These two scenarios show the recurring pattern: for HDB/EC buyers, MSR or LTV usually binds; for private/landed buyers, TDSR usually binds. The flow of the calculation matters, and every added dollar of existing debt has a disproportionate impact through the 30-year amortisation lever.
How to Legitimately Maximise Your Borrowing Ceiling
Nothing below involves gaming the system — each lever is recognised by banks and MAS. Together they can add S$200,000–S$400,000 to a buyer’s loan ceiling.
Close dormant credit facilities. A S$50,000 unused overdraft or a clutch of credit cards still hits TDSR via the 3% minimum rule. A week of admin before you apply for pre-approval can move the needle.
Pay down the car loan. High-instalment vehicle finance is the single most common TDSR killer. A S$1,000 monthly car note costs you roughly S$210,000 of home-loan capacity at 4.0%/30yr.
Lengthen the tenure (cautiously). A 30-year tenure beats a 25-year one on headline TDSR because the stress-rate instalment is lower — but watch the age-65 and 30-year triggers that knock the LTV down 20 points.
Co-apply with a higher earner. Joint applications aggregate income and debt. If spouses have different debt loads, consider which combination maximises the pooled headroom.
Formalise variable income. A commissioned sales professional with one year of written contracts may be haircut more heavily than one with two years of NOAs. Waiting one tax cycle can unlock meaningful capacity.
Use a Loan Assessment before committing. Banks in Singapore offer in-principle approval (IPA) at no cost. Three IPAs from different banks let you benchmark the figure.
How Singapore’s Framework Compares Globally
Singapore is not alone in prescribing debt-service ratios, but its combination is unusually strict. Hong Kong applies a 50% debt-service ratio with a 70% LTV cap for first-time owner-occupiers — broadly comparable but no separate MSR for public housing. The United Kingdom uses a 4.5× income loan-to-income ratio at most lenders (soft cap), with affordability stress-tested at 3 percentage points over the reversion rate. Australia’s prudential regulator APRA applies a serviceability buffer of 3 percentage points over the contracted rate — a rule-of-thumb approach rather than a hard ratio.
The common thread in all four jurisdictions is a stress-test mechanism designed to withstand a rate spike. Singapore’s 4.0% medium-term rate is higher (more conservative) than the contracted-rate buffers used in the UK and Australia, which is one reason Singaporean household debt has been more resilient through recent cycles than peers. MAS has been explicit that this is by design: household leverage is viewed as a systemic risk, not purely a consumer-protection issue.
What Might Come Next — The Forward View
The 4.0% stress rate has held since September 2022. Three scenarios could prompt a revision in the next 12–18 months:
Sustained higher long-term rates. If three-month SORA settles above 3.5% on a durable basis, MAS may nudge the medium-term rate to 4.25% or 4.5% to preserve the buffer it represents.
Renewed leverage in the private condo segment. If luxury-segment TDSR headroom is being used aggressively to bid up prime-district prices, expect tighter LTV on second/third loans rather than a TDSR change.
Public housing affordability stress. If HDB resale prices outrun wage growth materially, MSR could tighten from 30% to 25%. This would be the single most consequential move for first-time buyers.
None of the above is signalled by MAS at the time of writing (April 2026) — but the Financial Stability Review due in November 2026 is the data release to watch. Historically MAS has adjusted TDSR and MSR in the December statement that accompanies the cooling-measures package.
Frequently Asked Questions
1. Does TDSR apply to refinancing my existing mortgage?
For owner-occupied properties, a clean refinance without any cash-out and without extending the principal is generally exempted from TDSR under a carve-out MAS introduced to avoid penalising existing borrowers. If you take a cash-out top-up or increase the principal, the full TDSR test applies. For investment-property refinancing, TDSR applies in full regardless of cash-out status, so build in a review of your current debt profile before signing any refinance Letter of Offer.
2. How is TDSR calculated if I am self-employed with irregular income?
Banks use two years of Notice of Assessment (NOA) as the primary evidentiary source, take the simple average, apply the 30% haircut, and treat the resulting figure as your recognised gross monthly income. A particularly strong year — say a bumper bonus — will be smoothed. If you have less than two years of NOAs the bank will often decline or require a significantly larger down-payment. Incorporating yourself through a Pte Ltd does not change this; director’s remuneration drawn as salary is still subject to the haircut.
3. Can I borrow more by stretching the loan tenure?
Up to a point, yes. A 30-year tenure reduces the stress-rate instalment versus a 25-year tenure, increasing how much loan principal S$4,400 (in our worked example) can support. But two triggers cap the benefit: if your loan extends past age 65 or exceeds 30 years (25 for HDB), the LTV cap drops by 20 percentage points — from 75% to 55% on a first loan. The net effect is usually worse, not better. Most brokers recommend landing the tenure such that the loan concludes at or just before age 65.
4. Are joint-borrower applications better than going solo?
Usually, because they aggregate income while both parties still share the TDSR ceiling. The nuance is “income-weighted average age” for tenure calculations — if a 55-year-old and a 35-year-old co-apply, the bank blends their ages by income share to determine the maximum allowable tenure. Adding a much older co-applicant to a younger borrower can shorten the tenure and reduce the headroom on paper. Structured correctly, joint applications reliably produce higher approvals than solo for dual-income households.
5. What happens to TDSR if interest rates fall sharply?
Nothing, in the short run. The 4.0% stress rate is a regulatory input, not a market rate. Falling SORA means your actual monthly instalment shrinks and your actual debt-service ratio improves, but the ceiling at which MAS sets the TDSR bar is unchanged. Over a multi-year horizon, if rates settle well below 4.0% on a sustained basis, MAS may consider lowering the stress rate — but the precedent is that adjustments are infrequent (the last move was September 2022).
6. Does CPF Ordinary Account balance count as income for TDSR?
No. CPF OA is treated as equity (part of the down-payment and subsequent instalments), not as income. The monthly CPF contribution inflow also does not count as additional income — your CPF contributions are already a reduction from your gross pay, and gross pay is what banks use. The only way CPF affects borrowing capacity indirectly is through the Home Protection Scheme (for HDB loans) and through the cash-CPF split in the down-payment.
7. I was denied because of TDSR — what are my options?
First, get the denial reasoning in writing and compare it with a second IPA at a different bank — underwriting interpretations vary on edge cases, particularly around variable income and guarantor obligations. Second, tackle the debt side: clear a car loan, consolidate or close credit cards, discharge a guarantor role. Third, stretch the timeline: a fresh NOA next April may unlock the variable-income shortfall. Fourth, reduce the target property price — a 10% lower purchase price typically requires a proportionally smaller loan and therefore a smaller headroom. Finally, consider a joint application with a fixed-income parent (though this binds their future TDSR too).
This article is an editorial guide for general information only and does not constitute financial, legal or mortgage advice. The figures quoted reflect rules in force on the date of publication (April 2026) and may change. Confirm the authoritative position with the Monetary Authority of Singapore (MAS), the Housing & Development Board (HDB), your bank’s credit officer and a licensed mortgage broker before committing to any loan or property purchase. Interest-rate scenarios and worked examples are illustrative; your actual borrowing ceiling depends on the full underwriting review at application.
TDSR and MSR are the two regulatory ratios the Monetary Authority of Singapore (MAS) uses to decide how much home loan any Singapore buyer can take. Get these wrong in your budgeting, and the pre-approval letter from the bank will come back smaller than the deposit you have already put down on a flat. This guide breaks down what each ratio means, how they stack, and exactly how to calculate your own limit for 2026.
TDSR 55%: All your monthly debts (home loan, car loan, credit card minimums, student loans, personal loans) must stay at or below 55% of your gross monthly income.
MSR 30%: For HDB flats and new Executive Condos only — your monthly home loan alone must stay at or below 30% of gross monthly income. MSR sits on top of TDSR.
Stress rate: Both ratios are calculated using a 4.0% stress interest rate, not the actual package rate you are quoted.
Variable income: Bonuses, commission and rental income count at only 70% of their face value.
MSR is usually binding for HDB and EC buyers; TDSR is usually binding for private condo buyers.
What is TDSR and Why Does It Matter?
TDSR — Total Debt Servicing Ratio — was introduced in June 2013 as the backbone of Singapore’s sustainable-lending framework. It forces banks to look beyond your home loan and consider every monthly debt commitment you carry. If the sum of all those instalments exceeds 55% of your gross monthly income, the bank cannot extend you any further credit.
In practice, TDSR means that two borrowers on identical salaries can qualify for very different loan sizes if one of them also carries a car loan, a renovation loan, or a large outstanding credit-card balance. Because the ratio is regulatory rather than bank-specific, shopping around will not get you past it.
What counts in the 55% ceiling?
Housing loans (existing and the new one being applied for)
Car loans, motorcycle loans, and hire-purchase instalments
Renovation loans, education loans, personal loans
Minimum monthly payments on credit cards and overdraft facilities
Guarantor obligations on another party’s loan — even if you are not the primary borrower
What is MSR and When Does It Apply?
MSR — Mortgage Servicing Ratio — is a narrower, tougher cap that applies only when you are buying:
An HDB flat (BTO, Sale of Balance Flat, Open Booking, or resale), or
A new Executive Condominium (EC) directly from a developer, still within its minimum occupation period scheme.
MSR says that your monthly housing loan instalment alone must not exceed 30% of gross monthly income. Unlike TDSR, MSR does not let you compensate by showing you have no other debt — the housing instalment itself cannot breach the 30% line.
Private condos, landed property, and resale ECs after their 10-year privatisation milestone are not subject to MSR. Only TDSR applies. This is one of several reasons why private-property buyers on the same income can often borrow more than HDB buyers.
Figure 1: TDSR applies to every Singapore buyer; MSR adds a second, tighter cap for HDB flats and new ECs from developers.
How Banks Actually Calculate Your Limit
Here is the sequence every MAS-regulated bank follows when you submit a loan application:
Gross monthly income is totalled. Salary contributes 100%; variable income (bonus, commission, rent, freelance earnings) is haircut to 70%. For rental income, the bank also deducts a vacancy allowance.
Other monthly debts are added up. This includes a 3% notional minimum on your total credit-card outstandings if you do not pay in full.
Housing loan instalment is calculated at 4.0% stress rate, over your requested tenure (capped at 30 years for HDB, 35 for private). This is the rate used for ratio maths — not the 2.6% or 2.8% your package may quote.
Apply TDSR: (All debts + new housing loan at 4.0%) ÷ gross income must be ≤ 55%.
If HDB/new EC, apply MSR: New housing loan at 4.0% ÷ gross income must be ≤ 30%.
The loan is sized to the tighter of the two ceilings.
Worked example: couple earning S$16,000 a month
Consider a married couple with combined gross income of S$16,000, a car loan costing S$1,000 a month, and credit-card minimums of S$500 a month. They want to buy a 4-room resale HDB flat.
At 4.0% stress rate over 25 years, S$4,800/month supports a loan of approximately S$910,000. At the actual package rate of 2.6%, the real payment on that loan would be around S$4,127/month — giving the couple a S$673 monthly buffer once they move in.
Take away the car loan and the maths does not change — MSR still binds at S$4,800. Take away MSR (i.e. if they were buying a private condo instead), and the binding number becomes S$7,300 of TDSR headroom, translating to roughly a S$1,380,000 loan. Same couple, same income, different rule set, S$470k of extra purchasing power.
Stress Rate: The 4.0% That Quietly Decides Everything
MAS introduced the 4.0% medium-term interest rate floor (officially the “medium-term rate benchmark” or MTRB) in 2022, raising it from 3.5%. The stress rate is higher than virtually any home loan package in the market, which is the point — it builds in resilience against future rate rises.
Because the maths compounds, every 1% of stress-rate uplift cuts affordability by roughly 10%. That is why a package teaser rate of 2.5% does not actually buy you more house than a teaser of 3.0% — both are calculated at 4.0% for TDSR/MSR. What the lower package rate does buy you is cash-flow during the package term.
Variable Income: The 70% Haircut
If you earn a significant bonus, commission or rental income, the 30% haircut matters. Take a relationship manager earning S$10,000 base plus an average S$4,000 a month in commission. Gross looks like S$14,000. TDSR-countable gross is S$10,000 + (0.70 × S$4,000) = S$12,800.
To “grossed-up” income, banks typically require 24 months of commission history (12 for the more flexible ones). First-year hires with fat bonuses but short tenure often cannot count that income at all.
Three Levers to Increase Your Loan Ceiling
Extend the loan tenure (within the 30/35-year cap) — a longer tenure reduces the monthly instalment under the 4.0% stress calculation, freeing headroom under both ratios.
Retire consumer debt. Every S$1,000 of car-loan instalment taken off releases exactly S$1,000 of TDSR headroom. For HDB buyers, note this only helps if TDSR (not MSR) is the binding constraint.
Add a younger co-borrower. Tenure is capped at the weighted average age of all borrowers — bringing in a younger, income-earning co-borrower lifts the tenure ceiling and, by extension, your qualifying loan amount. Be deliberate about the legal and ownership implications before doing this.
Frequently Asked Questions
Does TDSR apply to refinancing?
For owner-occupied residential property, TDSR does not apply to refinancing of an existing loan (this is the “owner-occupier refinancing exemption”). For investment property, TDSR does apply on refinancing, with a debt-reduction plan over three years if you exceed the 55% cap.
Is rental income counted towards TDSR?
Yes. Rental income is haircut to 70% of face value, and banks further deduct a vacancy allowance. A 12-month tenancy agreement is usually required as evidence.
Does my existing home loan count if the property is rented out?
Yes, always. Every housing loan you are servicing — owner-occupied or rented — enters the TDSR calculation on the debt side, regardless of whether the rental income covers it.
Can I get a higher loan if I pay down my credit card before applying?
Yes, provided the payment clears before your bank pulls the credit bureau report. Banks calculate TDSR based on bureau-reported outstandings — pay down early enough for the next monthly report cycle.
What happens if my income drops after I take the loan?
TDSR is tested only at origination and on refinancing of investment property. A mid-loan income drop does not trigger a call on your loan — you simply need to keep paying the contracted instalment.
What to Do Next
