Singapore Property Valuation Guide 2026: COV, Bank Valuation, LTV and How to Appeal
🔍 Quick Answer — Singapore Property Valuation & COV (2026)
- Property valuation is a formal assessment of a property’s open-market worth, conducted by an IRAS-approved valuer. Banks and HDB use it to set the maximum loan amount.
- Three main types: desktop/automated (bank screening), in-house bank panel valuation (most home loans), and full independent valuation (HDB resale, disputes, appeals).
- Cash Over Valuation (COV) is the gap between what you agree to pay and what the official valuation says the property is worth. COV must be paid 100% in cash — it cannot be funded by your CPF or bank loan.
- LTV impact: your bank loan is capped at 75% of the lower of purchase price or valuation. If you pay above valuation, your loan shrinks and your cash requirement rises.
- In 2025–26, roughly 55–63% of HDB resale transactions involve some COV, with median COV ranging from S$18,000 to S$31,000 depending on flat type.
- HDB resale valuations are commissioned through HDB’s Resale Portal; private property valuations are arranged by your bank or yourself for dispute purposes.
- You can appeal a valuation by engaging a second IRAS-approved valuer; if results differ by more than 10%, a third valuer may be appointed as arbitrator.
- Stamp duties (BSD, ABSD) are calculated on the higher of purchase price or valuation — so even if valuation is lower, you pay stamp duty on what you actually agreed to pay.
Understanding property valuation in Singapore is essential for every buyer — whether you are purchasing an HDB resale flat in Ang Mo Kio or a condominium in the River Valley. The valuation determines how much your bank will lend you, how much CPF you can use, and, crucially, whether you need to top up extra cash in the form of Cash Over Valuation (COV).
Valuation in Singapore is governed by the Inland Revenue Authority of Singapore (IRAS), which maintains a register of approved valuers. The Urban Redevelopment Authority (URA) and HDB use valuation data to track market trends and publish the official Property Price Index (PPI) and Resale Price Index (RPI). For buyers and sellers, getting the valuation right — and knowing how to respond when a valuation comes in lower than expected — can mean the difference between a smooth transaction and a costly one.
Types of Property Valuation in Singapore
Not all valuations are the same. Depending on the purpose — an initial loan enquiry, an HDB resale purchase, or a legal dispute — different valuation methodologies apply, commissioned by different parties at different costs.

Desktop / Automated Valuation Model (AVM)
Banks use AVMs for initial screening and mortgage top-up requests. The model draws on recent transacted prices from URA’s REALIS database and HDB resale records. AVMs are fast (often instant) and free to the borrower, but they are indicative only — they carry no weight in a formal sales transaction and cannot be appealed.
In-House Bank Panel Valuation
When you apply for a home loan, your bank appoints a valuer from its approved panel — typically a firm such as Edmund Tie, JLL, or Savills Research. The cost ranges from free to S$200, and results come in one to three working days. This is the valuation used to determine your maximum loan quantum and LTV ratio. You can request the bank review its panel valuation, though success depends on documentary justification (comparable transactions, unique features of the property).
Full Independent Valuation
For HDB resale transactions, buyers must obtain a valuation through the HDB Resale Portal after the Option to Purchase (OTP) is granted. HDB appoints an IRAS-approved valuer from a rotating panel. The cost (typically S$200 – S$400, borne by the buyer) is built into the resale procedure. For private property disputes or legal purposes, buyers engage independent valuers directly; fees range from S$300 to S$600 for a standard residential unit.
Cash Over Valuation (COV): What It Is and Why It Matters
Cash Over Valuation — universally abbreviated as COV — is the premium you agree to pay above a property’s official valuation. COV became a significant market phenomenon in Singapore’s HDB resale market after the 2009–2013 bull run, when COV of S$40,000–S$80,000 became common. The government introduced resale price disclosure requirements in 2014, which dampened COV; however, the 2021–2022 post-pandemic demand surge saw COV re-emerge as a negotiating norm.
COV is critical for buyers to understand for three reasons: it is paid entirely in cash (no CPF, no bank loan), it does not reduce your stamp duty liability (BSD and ABSD are charged on purchase price, not valuation), and it increases your total upfront cash outlay beyond what most first-time buyers anticipate.

Industry data for 2025–26 shows that 4-room resale flats in mature estates consistently attract the highest COV in absolute dollar terms — median around S$31,000 — because they offer the largest usable space within HDB’s most popular segment. Executive flats attract lower COV (around S$18,000) partly because fewer buyers qualify for the larger loan sizes required. These figures are estate-specific averages; popular blocks in Bishan, Queenstown, Bukit Timah, and Clementi frequently command COV of S$50,000–S$80,000 in 2025–26.
How Bank Valuation Affects Your Loan and LTV
The LTV (Loan-To-Value) ratio determines the maximum bank loan you can obtain. For a first residential property purchased with a bank loan (not HDB loan), the maximum LTV is 75% of the lower of purchase price or bank valuation. This means if the bank values the property at less than you agreed to pay, your loan quantum shrinks — and the shortfall must be covered by a combination of CPF (up to the Valuation Limit) and cash (for COV).
CPF usage for private property is further constrained by two limits set by the CPF Board: the Valuation Limit (VL) and the Withdrawal Limit (WL). The VL equals the bank valuation at the time of purchase; CPF cannot be used beyond the VL without a top-up. The WL is 120% of the VL for properties with remaining lease of at least 60 years.

Worked Example: The Wongs Buy a 4-Room Resale in Toa Payoh
Scenario: Mr & Mrs Wong, SC + SC couple, buying a 4-room HDB resale flat in Toa Payoh
Agreed purchase price: S$730,000
HDB Resale Portal valuation (full independent): S$700,000
COV: S$30,000 (cash only)
Loan type: HDB Concessionary Loan @ 2.60% p.a., 25-year tenure
Max HDB loan (80% of valuation): 80% × S$700,000 = S$560,000
BSD payable: S$730,000 — BSD tiers: 1% × S$180K + 2% × S$180K + 3% × S$370K = S$1,800 + S$3,600 + S$11,100 = S$16,500
Monthly instalment (S$560K @ 2.60%, 25yr): approx. S$2,535/month — MSR = S$2,535 / (combined income assume S$10,000) = 25.4% ✓ (below 30% MSR limit)
CPF usage: From combined CPF OA, the Wongs use CPF up to the valuation limit (S$700,000 – S$560,000 = S$140,000 in own funds needed; CPF OA available S$100,000 used for downpayment)
Cash required breakdown:
- COV (cash only): S$30,000
- 5% downpay on purchase price (cash, cannot be CPF): S$36,500
- Remaining 15% downpay (CPF OA): S$109,500 (but capped by CPF available)
- BSD: S$16,500 (CPF or cash)
- Legal fees: ~S$3,000
Total minimum cash outlay: S$30,000 (COV) + S$36,500 (5% cash) = S$66,500 cash minimum, plus CPF for balance downpayment and BSD.
Key takeaway: the S$30,000 COV is the most painful item — it is pure cash, not eligible for CPF or loan financing, and it must be paid before the completion of the sale.
How to Appeal a Property Valuation in Singapore
If a valuation comes in lower than expected, buyers and sellers have recourse — but the process differs for HDB resale and private property.
HDB resale: After HDB’s appointed valuer issues a valuation, either party can request a review through HDB’s customer service within the prescribed period. HDB may appoint a second valuer. The process typically takes an additional three to five working days and costs an additional S$200 – S$400. If the revised valuation is higher, the transaction proceeds on the new figure; if not, the original stands and the buyer must fund the COV in cash.
Private property: The buyer engages a second IRAS-approved valuer independently. If the two valuations differ by more than 10%, a third valuer — agreed upon by both parties or appointed by the Singapore Institute of Surveyors and Valuers (SISV) — acts as arbitrator. The arbitrator’s valuation is binding. This process can take two to three weeks and cost S$600 – S$1,500 in total valuation fees.
Practical tip: Before exercising an OTP at a price that you suspect may exceed valuation, request an indicative valuation from an independent valuer (S$200 – S$300). This gives you negotiating leverage with the seller, and may save you a far larger COV payment later.
What Might Come Next: Valuation Trends in 2H 2026
Singapore’s HDB resale market has seen elevated COV levels since 2021. In 2H 2026, a few forces may moderate COV pressure: a record GLS supply pipeline of approximately 9,320 units on the 2026 Confirmed List (the highest since 2013), three consecutive years of cooling measures maintaining ABSD rates, and modestly declining SORA rates (the three-month compounded SORA was approximately 3.05% as at mid-2026, down from a 2024 peak of 3.75%). If new private supply dampens upgrader demand for resale HDB, COV may ease in non-mature estates. Mature estate and prime location HDB resale flats in Bishan, Queenstown, and Kallang/Whampoa — where supply of comparable units is structurally limited — are likely to maintain higher COV premiums through 2026. Watch the Q3 2026 HDB Resale Statistics (expected October 2026) for signals.
Frequently Asked Questions
Can I use CPF to pay COV?
No. Cash Over Valuation must be paid entirely in cash. The CPF Ordinary Account can only be used up to the bank’s valuation (the Valuation Limit). The gap between your purchase price and the valuation — the COV — is not recognised by either CPF Board or your bank, and must come from your own liquid funds. This is one of the most common surprises for first-time HDB resale buyers.
Does COV affect the stamp duty I pay?
Yes — but not in the direction buyers might hope. Buyer’s Stamp Duty (BSD) and Additional Buyer’s Stamp Duty (ABSD) are calculated on the higher of purchase price or valuation. If you pay S$730,000 for a flat valued at S$700,000, your stamp duty is calculated on S$730,000, not S$700,000. This means paying COV also slightly increases your stamp duty bill.
Who appoints the valuer for an HDB resale flat — the buyer or the seller?
For HDB resale transactions, the valuer is appointed by HDB through its Resale Portal — neither the buyer nor the seller chooses the specific firm. After the Option to Purchase is granted and the buyer submits the resale application online, HDB triggers the valuation process automatically. The cost (typically S$200 – S$400) is borne by the buyer. The valuation is delivered to both parties within approximately two to three working days.
What happens if the bank valuation for a private property comes in lower than my agreed purchase price?
Your maximum loan quantum drops to 75% of the bank’s valuation — not 75% of your purchase price. The shortfall between what you agreed to pay and the loan you can obtain must be funded by a combination of CPF (up to the Valuation Limit) and cash. If the difference is large, you may need to renegotiate with the seller, appeal the valuation, or walk away — subject to the terms of your OTP and any Option Fee already paid.
Is there a way to find out the valuation before exercising the OTP?
Yes. You can engage an independent IRAS-approved valuer for an indicative desktop or full valuation before you exercise the OTP (typically within the 14-day OTP period). The cost is S$200 – S$400. This is especially prudent for older resale flats or those with unique features (high floor, renovated extensively, or conversely flood-damaged or structurally altered) where the automated valuation models may be unreliable. A pre-OTP valuation gives you a firm basis for negotiating the purchase price with the seller.
Are stamp duties calculated on the purchase price or the valuation?
IRAS charges BSD and ABSD on the higher of: (a) the agreed purchase price as stated in the Sale and Purchase Agreement, or (b) the market value as assessed by an IRAS-approved valuer. In most resale transactions the purchase price is higher (because COV applies), so stamp duty is based on the purchase price. In distressed sale situations where a property sells below valuation, stamp duty is charged on the valuation — the floor protects revenue.
Can I appeal an HDB resale valuation if I think it is too low?
Yes. You can request a review through HDB’s Resale Portal or customer service hotline. HDB will appoint a second IRAS-approved valuer from its panel. The review typically takes an additional three to five working days and costs an additional fee (approximately S$200 – S$400, borne by the requesting party). If the revised valuation is higher, the transaction proceeds on the higher figure. If the revised valuation is unchanged or lower, the original valuation stands. Note that in a strong seller’s market, both valuations often come in at or near the agreed price — the COV simply has to be funded in cash.
