Singapore HDB Resale Procedure Guide 2026: Step-by-Step for Buyers and Sellers
Quick Answer: HDB Resale in 2026 — Key Points at a Glance
- Who can buy: Singapore Citizens (SC) and Permanent Residents (SPR) who form an eligible family nucleus. At least one applicant must be SC for most schemes. No private property ownership within 30 months.
- 10-step process: From eligibility check through key collection, the full process typically spans 3–4 months after the Option to Purchase (OTP) is granted.
- OTP mechanics: Seller grants the OTP upon receiving a 1% option fee (cash). Buyer has 21 calendar days to exercise it by paying an additional 4%. Total deposit = 5% of purchase price.
- Stamp duty deadlines: Buyer’s Stamp Duty (BSD) and any Additional Buyer’s Stamp Duty (ABSD) must be paid within 14 days of exercising the OTP.
- Cash Over Valuation (COV): If the agreed price exceeds HDB’s assessed value, the difference is COV — payable entirely in cash. CPF and loans cannot cover COV.
- Application window: Both buyer and seller must submit their resale applications via the HDB Flat Portal within 7 days of OTP exercise. HDB approval takes approximately 8 weeks.
- HDB loan income ceiling: S$14,000/month for families. Above this, buyers must take a bank loan.
What is an HDB Resale Flat — and Who Oversees the Process?
An HDB resale flat is a public housing unit sold by an existing owner on the open market, as opposed to a Build-To-Order (BTO) flat purchased directly from the Housing and Development Board at a subsidised price. Resale flats offer immediate or near-term occupation (subject to the 3–4 month processing period), access to more established locations, and a wider choice of unit types — including larger flat sizes such as 5-room and executive flats that are rarely available in new BTO exercises.
The Housing and Development Board (HDB) administers buyer and seller eligibility, the Minimum Occupation Period (MOP), the resale application and approval process, and housing loan eligibility. The Inland Revenue Authority of Singapore (IRAS) collects Buyer’s Stamp Duty and Additional Buyer’s Stamp Duty. The Council for Estate Agencies (CEA) licenses and regulates property agents involved in the transaction. The Central Provident Fund (CPF) Board oversees the use of CPF Ordinary Account (OA) savings for the purchase price and, in some cases, for monthly loan repayments.
Understanding which body governs which step — and the strict deadlines attached to each — is the foundation of a smooth HDB resale transaction.
Eligibility Requirements for HDB Resale
Before proceeding, both buyers and sellers must confirm their eligibility under HDB’s framework. Sellers must have satisfied the five-year Minimum Occupation Period (MOP) before listing a flat that was purchased directly from HDB or under a resale grant. Buyers must meet citizenship, family nucleus, and (if using an HDB loan) income ceiling requirements.
Citizenship: At least one buyer must be a Singapore Citizen. SPR families may purchase resale flats but receive no priority in newer BTO exercises. Single Singapore Citizens aged 35 and above may purchase 2-room Flexi flats under the Single Singapore Citizen Scheme, or 5-room and smaller resale flats in non-mature estates in certain conditions.
Family nucleus: Acceptable family nuclei include married or engaged couples, parent-and-child families, children orphaned before 35, and the Joint Singles Scheme (two eligible SC singles aged 35+). The family nucleus requirement ensures public housing reaches genuine households.
Income ceiling for HDB housing loan: S$14,000/month combined gross income for families; S$7,000 for singles. If household income exceeds the applicable ceiling, you must finance your purchase with a bank loan. There is no income ceiling simply to buy a resale flat — the ceiling only triggers when applying for an HDB concessionary loan or certain CPF Housing Grants.
Property ownership restriction: Buyers must not own any private residential property (local or overseas) at the time of application, and must not have disposed of any private property within 30 months before the resale application date.
HFE Letter: If you intend to use an HDB housing loan or CPF Housing Grants, you must obtain a valid HDB Flat Eligibility (HFE) letter before the OTP stage. Apply via the HDB Flat Portal at hdb.gov.sg. The HFE letter confirms your eligibility, the loan quantum you qualify for, and any grants you are entitled to.
Step-by-Step: The 10-Stage HDB Resale Process
The HDB resale process unfolds across ten distinct stages, each with its own actors, documents, and deadlines. Buyers and sellers typically engage separate law firms and, optionally, CEA-registered property agents to navigate the process.
Step 1 — Check eligibility. Use HDB’s eligibility checker and apply for your HFE letter if you plan to use an HDB loan or grants. This step should be completed well before you start viewing flats.
Step 2 — Arrange financing. Obtain an HFE letter (for HDB loan) or an In-Principle Approval (IPA) from a bank. The IPA indicates how much the bank is prepared to lend and at what indicative rate. Having pre-approved financing strengthens your negotiating position.
Step 3 — Register intent on HDB Flat Portal. Sellers register their intent to sell; buyers register their intent to buy. This activates the resale portal for your transaction and confirms that both parties are eligible to proceed.
Step 4 — Negotiate and agree on price. Buyer and seller negotiate the transaction price. Check recent resale transaction data via HDB’s Resale Statistics and URA’s REALIS portal (ura.gov.sg) to benchmark the price. Note that if the agreed price exceeds HDB’s valuation, the difference (COV) must be paid entirely in cash.
Step 5 — Seller grants the OTP. The seller issues the Option to Purchase and receives a 1% option fee from the buyer (minimum $1, maximum 1% of the agreed price). This fee is non-refundable if the buyer does not exercise the OTP.
Step 6 — Buyer exercises the OTP. Within 21 calendar days of the OTP date, the buyer pays an additional 4% of the agreed price to exercise the option. The total deposit (1% + 4% = 5%) is credited towards the purchase price at completion. If the buyer does not exercise, the 1% option fee is forfeited and the seller may proceed with other buyers.
Step 7 — Submit resale application. Within 7 days of exercising the OTP, both buyer and seller independently submit their portions of the resale application via the HDB Flat Portal. Required documents include identity documents, the OTP, HFE letter (buyer), and financial data.
Step 8 — Endorse resale documents. HDB issues the resale documents for endorsement, including the Certificate of Eligibility. Both parties (and their solicitors) review and sign the required documents.
Step 9 — HDB approval. HDB reviews the application and issues an approval notice, typically within approximately 8 weeks of submission. The approval notice contains the completion date.
Step 10 — Completion and key collection. On the scheduled completion date, the buyer pays the balance of the purchase price (using CPF OA and/or cash), legal fees are settled, and keys are handed over at HDB Hub or via a virtual appointment. The buyer becomes the registered owner upon completion.
Option to Purchase: Mechanics, Deadlines and Risks
The Option to Purchase is a legally binding contract that gives the buyer the exclusive right — but not the obligation — to purchase the flat at the agreed price within the option period. Understanding its mechanics is critical, as several major financial commitments are triggered by the OTP date.
1% option fee: Paid by the buyer to the seller upon grant of OTP. This sum is deducted from the purchase price at completion if the buyer proceeds. It is forfeited entirely if the buyer does not exercise.
21-day exercise window: The buyer has 21 calendar days from the OTP date to decide whether to proceed. This period allows time to finalise financing, conduct legal due diligence, and confirm CPF usage. Do not grant or exercise an OTP before securing your In-Principle Approval or HFE letter.
4% exercise fee: Paid when exercising the OTP. Combined with the 1% option fee, the buyer has now paid 5% of the purchase price as a deposit. This sum is credited towards the purchase price at completion.
7-day submission window: Within 7 days of OTP exercise, both buyer and seller must submit their portions of the resale application to HDB. Missing this deadline can delay the entire transaction and may require the parties to restart certain steps.
Stamp duty deadline: BSD (and ABSD, if applicable) must be paid to IRAS within 14 days of the OTP exercise date — not from completion. For a S$720,000 resale flat, BSD totals S$16,200. Penalties apply for late payment.
Stamp Duty, COV and Upfront Costs
Buyers of HDB resale flats are subject to Buyer’s Stamp Duty (BSD) on all properties and, depending on their citizenship status and number of properties owned, Additional Buyer’s Stamp Duty (ABSD).
| BSD Tier (as at 3 August 2026) | Rate | BSD on S$720,000 Flat |
|---|---|---|
| First S$180,000 | 1% | S$1,800 |
| Next S$180,000 | 2% | S$3,600 |
| Next S$640,000 | 3% | S$10,800 (on S$360k portion) |
| Total BSD (S$720,000 flat) | S$16,200 |
ABSD rates in 2026: Singapore Citizens pay 0% ABSD on their first residential property, 20% on their second, and 30% on their third and beyond. Singapore Permanent Residents pay 5% on their first and 30% on their second. Foreigners pay 60% on all purchases. ABSD is calculated on the higher of the purchase price or market value, and must be paid within the same 14-day window as BSD.
Cash Over Valuation (COV): HDB conducts a valuation of the flat during the resale process. If the agreed transaction price exceeds this valuation, the difference is considered COV. COV cannot be financed by an HDB or bank loan, nor can it be paid using CPF OA savings. It must be paid entirely in cash. Buyers should factor COV risk into their cash-available calculation before entering into an OTP.
Financing Your HDB Resale Purchase
Buyers may finance an HDB resale flat using an HDB concessionary loan, a bank loan, or a combination of CPF savings and cash. The Mortgage Servicing Ratio (MSR) cap of 30% of gross monthly income applies to both HDB and bank loans for HDB flat purchases, limiting the maximum loan quantum. The Total Debt Servicing Ratio (TDSR) cap of 55% of gross monthly income also applies, covering all debt obligations.
HDB loan: Fixed interest rate of 2.6% per annum (0.1% above CPF Ordinary Account rate as at 2026). Maximum LTV is 80% of the lower of the purchase price or valuation. Requires an HFE letter. Allows flexible early repayment. Available only to SC and SPR buyers meeting income ceiling requirements.
Bank loan: Rates are typically SORA-based, currently ranging from approximately 3.0–4.0% per annum for typical packages in 2026. Maximum LTV is 75% for the first housing loan (50% for second, 35% for third and beyond). Requires an IPA from the bank. May offer more competitive rates in a low-rate environment but carries repricing risk.
Worked Example: The Lim Family Buying S$720,000 Queenstown Resale Flat
Profile: Mr & Mrs Lim, both Singapore Citizens, combined gross monthly income S$9,000. First residential property. Mr Lim aged 38, Mrs Lim aged 36.
Property: 5-room HDB resale flat, Queenstown. Agreed price: S$720,000. HDB valuation: S$710,000. COV = S$10,000.
BSD: 1% × S$180k = S$1,800 + 2% × S$180k = S$3,600 + 3% × S$360k = S$10,800 = S$16,200
ABSD: S$0 (first property, both SC)
HDB loan: 80% LTV = S$576,000 @ 2.6% p.a., 25-year tenure. Monthly repayment ≈ S$2,617. MSR check: S$2,617 ÷ S$9,000 = 29.1% < 30% ✓. TDSR check: S$2,617 ÷ S$9,000 = 29.1% < 55% ✓ (no other debts assumed).
Down payment: 20% × S$720k = S$144,000 (from CPF OA, assumed sufficient).
- Day 0 (OTP grant): Cash option fee = S$7,200 (1%)
- Day 21 (OTP exercise): Cash exercise fee = S$28,800 (4%)
- Within 14 days of exercise: BSD S$16,200 + COV S$10,000 = S$26,200 (cash)
- At completion: Remaining CPF OA used: S$144,000 − S$7,200 − S$28,800 = S$108,000. Legal fees: ~S$3,800 (cash). HDB loan S$576,000 disbursed directly to seller.
Total upfront cash required: approximately S$66,200 (S$7,200 + S$28,800 + S$26,200 + S$3,800 + S$300 for HDB admin). CPF OA covers the remaining S$108,000 of the down payment at completion.
Why the HDB Resale Market Matters in 2026
HDB resale prices have risen consistently since 2021, driven by supply constraints during the COVID-19 construction pause, strong upgrader demand from the large cohort of BTO buyers who completed their MOP, and a preference among buyers for larger, immediately available flats in established locations. The resale market serves a critical function: it provides housing for Singaporeans who need a home faster than BTO timelines allow, particularly newlyweds, growing families, and those with elderly parents nearby.
Industry figures show that resale median prices for 5-room flats in central areas now regularly breach the S$700,000 mark, with prime Queenstown and Bishan transactions exceeding S$800,000 for desirable units. For prospective buyers, this underscores the importance of understanding COV risk, having sufficient cash reserves, and calibrating loan quantum carefully against the MSR ceiling.
For sellers, the strong market represents an opportunity to realise significant appreciation — but proper understanding of CPF accrued interest (which must be returned to your CPF account upon sale) and outstanding loan balances is essential to accurately calculate net proceeds.
What Might Come Next for HDB Resale
Industry observers anticipate that HDB may introduce targeted policy refinements if resale flat prices for standard flat types in mature estates continue to trend above S$700,000 at the median. Potential measures discussed include extending the MOP for certain flat types, adjusting the CPF usage limits for older flats, or introducing enhanced grant frameworks to moderate demand in specific segments. The government has consistently stated that maintaining housing affordability is a key policy objective, and the full resale market cycle — including cooling measures — should be considered in long-term financial planning. These remain speculative; buyers should rely on current official policies at HDB and IRAS when transacting.
Frequently Asked Questions: HDB Resale Procedure 2026
Can Singapore Permanent Residents buy HDB resale flats?
Yes, Singapore Permanent Residents (SPRs) may purchase HDB resale flats, subject to forming an eligible family nucleus. A family comprising two SPRs (without an SC) may purchase a resale flat, though they are not eligible for the most favourable CPF Housing Grants, which are reserved for SC households. SPRs pay a higher ABSD rate (5% on first, 30% on second property) compared to SCs. Note that SPRs cannot buy BTO flats directly from HDB — only resale flats on the open market.
What happens if I miss the 7-day window to submit the resale application after exercising the OTP?
The 7-day submission window after OTP exercise is strictly enforced. If both parties fail to submit on time, the resale application cannot proceed under that OTP, and the transaction may need to restart with a new OTP. This effectively means the buyer forfeits the 5% deposit (1% + 4%) unless both parties agree to an extension and can justify the delay to HDB. Property agents and solicitors routinely track these deadlines; ensure your legal advisers are appointed before the OTP stage.
Can I use CPF Ordinary Account savings to pay the option fee and exercise fee?
No. The option fee (1%) and exercise fee (4%) paid at the OTP stage must be paid in cash. CPF OA savings can only be used at the completion stage — specifically to pay the down payment (above the loan quantum), partial BSD in some cases, and subsequent monthly loan repayments (subject to HDB or bank approval). This means you need at least 5% of the purchase price in cash available before entering into an OTP. For a S$720,000 flat, that is S$36,000 in cash, plus BSD and legal fees.
How is HDB’s valuation of a resale flat determined, and what if the market price is higher?
HDB engages a Certified Appraiser (registered with the Singapore Institute of Surveyors and Valuers) to conduct a market valuation of the flat, typically shortly after the resale application is submitted. The valuation is based on comparable transactions, flat condition, storey, and location. If the agreed price exceeds the valuation, the difference is Cash Over Valuation (COV) — the buyer must pay this entirely in cash (no CPF, no loan). Sellers typically price above valuation in a strong market; buyers who cannot accommodate COV may need to negotiate the price down to valuation or seek a flat where the transaction price matches or falls below the assessed value.
What is the difference between an HDB resale flat and a Design, Build and Sell Scheme (DBSS) flat?
Design, Build and Sell Scheme (DBSS) flats were a now-discontinued category of public housing developed by private developers but sold under HDB rules. They are indistinguishable from standard HDB resale flats in terms of the resale procedure — DBSS flats go through the same HDB resale process, are subject to the same MOP, and can be purchased using CPF OA and HDB loans. The DBSS scheme produced 13 projects between 2006 and 2012; no new DBSS projects have been launched since. Buyers will encounter DBSS flats on the resale market like any other HDB unit.
How long does HDB approval take, and can the completion date be accelerated?
HDB approval for a resale application currently takes approximately 8 weeks from the submission date, provided all documents are in order and there are no eligibility issues. The completion date is set by HDB in the approval notice — typically 6–8 weeks after approval, giving a total end-to-end timeline of approximately 3–4 months from OTP exercise. Completion dates generally cannot be significantly accelerated, as HDB coordinates across multiple parties (buyer, seller, solicitors, CPF Board). Sellers who need to synchronise with a new home purchase should factor this timeline carefully into their planning.
