Selling your HDB flat in Singapore is a four-stage process — Intent to Sell, marketing and negotiation, OTP, and completion. Each stage has its own legal document, its own timing constraints, and its own price-breaking pitfalls. This 2026 guide walks through the full sequence from the seller’s side.
See HDB’s official selling page for the regulatory details. This guide explains the practical mechanics.
Quick Answer — Selling an HDB Flat
Check your MOP — 5 years from key collection for most flats.
Register Intent to Sell on the HDB Resale Portal.
List, view, negotiate — typically 4–10 weeks.
Grant the Option to Purchase (OTP) — S$1,000 option fee, 21-day validity.
Both parties submit the resale application — ~8 weeks HDB processing.
Completion appointment at HDB Hub — hand over keys.
Total: 3–4 months from listing to completion.
Four milestones between listing decision and handing over keys.
Step 1: Check Your MOP
You cannot sell an HDB flat until the Minimum Occupation Period (MOP) has been fulfilled. For most modern flats this is 5 years from key collection; for Plus and Prime flats it is 10 years. See our MOP guide for the exceptions and consequences of breach.
Time spent overseas for more than 6 months at a stretch does not count. If you have been posted abroad, verify with HDB that your effective MOP is what you think it is.
Step 2: Register Intent to Sell
Log into the HDB Resale Portal with Singpass and submit Intent to Sell. This is valid for 12 months. It:
Confirms your eligibility to sell (MOP, ethnic quota impact)
Allows you to appoint a licensed property agent
Triggers HDB’s valuation pipeline when an OTP is later granted
Gives buyers assurance that the flat is legitimately for sale
Step 3: Price, List and Negotiate
HDB resale is now in a tight market with COV back on the table. Price correctly:
Pricing benchmarks
Recent transacted prices on the HDB Resale Portal for the same block, type, and floor
Recent COV spread — has the estate been transacting above or below valuation?
Remaining lease — a shorter lease narrows the buyer pool considerably
Block-level ethnic quota — a block that is “closed” to major ethnic groups has a reduced buyer pool and attracts weaker offers
Agent vs no-agent
The HDB Resale Portal is designed to let sellers transact without an agent. However, a good agent will:
Run marketing on PropertyGuru, 99.co, and Facebook/IG for 2–4 weeks
Coordinate viewings (typically evenings and weekends)
Shepherd both parties through resale application submission
Typical seller-side commission in 2026 is 2% of the transacted price. See our agent commission guide.
Step 4: Grant the OTP
Once you and the buyer agree on a price, you grant the OTP. The option fee is fixed at S$1,000. The buyer then has 21 calendar days to exercise by paying the exercise fee (up to S$4,000 more, so total S$5,000 maximum). Key points:
If the buyer fails to exercise, you retain the S$1,000 option fee.
If the buyer does exercise, the sale becomes unconditional. You cannot then grant an OTP to another buyer.
Valuation is requested at this point — if it comes in below the agreed price, the buyer must pay the shortfall in cash (COV).
Step 5: Resale Application
Within 7 days of OTP exercise, both seller and buyer log into the HDB Resale Portal and jointly submit the resale application. You will:
Confirm the agreed price and terms
Select your conveyancing solicitor (HDB Legal or private)
Complete the Resale Checklist — a set of confirmations from both parties
Pay the administrative fee (S$80 for 1-2 room, S$120 for 3-room and above)
HDB then processes the application, targeted at 8 weeks. During this time, HDB will audit your ownership, verify the buyer’s eligibility, compute CPF refunds, and arrange the completion appointment.
Step 6: Completion Appointment
Typically 8–12 weeks after the resale application, you attend the completion appointment at HDB Hub. Both parties sign the transfer documents, CPF refund is credited to your Ordinary Account, the buyer’s loan is disbursed, and you hand over the keys.
What Happens to Your CPF and Sale Proceeds
The sale proceeds flow in this sequence:
Outstanding HDB or bank loan is repaid in full from the proceeds.
CPF refund — the principal you used from CPF, plus accrued interest, is refunded back into your CPF Ordinary Account. This can be substantial on a flat you have lived in for 10+ years.
Balance — what remains is your cash-in-hand from the sale.
If the flat has appreciated slowly or you used a large CPF component, the CPF refund may consume most of the proceeds, leaving little cash. This is the “negative sale” scenario and a real risk for short-lease resale.
Worked Example: Selling a S$680k 4-Room Flat
You bought the flat 9 years ago for S$420k, paid using S$100k CPF (principal) and a S$300k HDB loan, and have S$150k outstanding on the loan:
Item
Amount
Sale price
S$680,000
Less: outstanding HDB loan
(S$150,000)
Less: CPF refund (principal + 9yr accrued @ 2.5%)
(S$125,000)
Less: agent commission (2%)
(S$13,600)
Less: legal fees
(S$500)
Net cash in hand
S$390,900
CPF Ordinary Account now holds
S$125,000 more
Common Pitfalls
Accepting an offer before verifying buyer HFE status — if the buyer cannot get HFE, the deal collapses.
Ethnic quota surprise — HDB rejects the application because the sale would push the block over its EIP cap for the buyer’s ethnic group.
Valuation shortfall — the buyer walks away if the valuation is too low and they cannot fund the cash COV.
Underestimating CPF accrued interest — many sellers find far less cash in hand than expected.
Overestimating the flat — overpricing leads to extended listing periods and ultimately a lower final transacted price.
FAQ — Selling an HDB Flat 2026
Can I sell my flat before MOP is fulfilled?
Only under exceptional circumstances (divorce, death, financial hardship) and with HDB’s explicit approval. Otherwise, sale before MOP is not permitted.
How much cash will I actually get from the sale?
Sale price minus outstanding loan minus CPF refund minus agent commission minus legal fees. For most owners 5–10 years in, cash in hand is 40–60% of sale price.
Do I pay Seller Stamp Duty on an HDB resale?
Only if you have owned the flat for less than 3 years (very rare because of MOP). See our SSD guide.
Can I reject a buyer after accepting their OTP offer?
No. Once the OTP is granted and the buyer has paid the option fee, you are legally bound to sell to them if they exercise within 21 days.
What if the buyer’s HDB loan gets denied?
The buyer can walk away from the OTP, forfeiting the option fee (and exercise fee if already paid). You are then free to re-list and sell to another buyer.
Disclaimer: HDB processes, fees and scheme rules change over time. Verify the current rules with HDB before committing to sale. Consult your conveyancing lawyer for advice on your specific situation.
Buying an HDB resale flat in Singapore in 2026 is a process with clear, legally-defined stages. Miss one, and the deal either stalls or collapses entirely. This guide walks you through every step in the exact order you will actually encounter it — from securing your HDB Flat Eligibility (HFE) letter to collecting the keys.
For the official rules, refer to the HDB Resale Buying page. This article explains what those rules mean in practice and how the numbers add up for a typical 2026 buyer.
Quick Answer — The HDB Resale Buying Process
Apply for HFE letter on the HDB Flat Portal (~2 weeks processing).
Shortlist and view flats (typically 2–6 weeks).
Negotiate, then receive the OTP from the seller (S$1,000 option fee).
Exercise the OTP within 21 days with the exercise fee (up to S$4,000 more).
Submit the resale application on the HDB Resale Portal.
Complete the purchase at the HDB Hub appointment and collect keys.
Total elapsed time: typically 12–16 weeks from OTP to keys.
The five stages of buying an HDB resale flat, from HFE letter to keys.
Step 1: Apply for Your HFE Letter
The HDB Flat Eligibility (HFE) letter is the gating document for any HDB purchase. It confirms three things in a single statement: whether you are eligible to buy, how much CPF housing grant you qualify for, and the maximum HDB loan you can take.
You apply through the HDB Flat Portal using Singpass. The portal will check your household income, ages, citizenship, and existing property holdings. Processing usually takes around two weeks — but longer if HDB needs clarification on income or existing flat ownership.
The HFE letter is valid for six months, and you cannot exercise any OTP without one. Budget for your HFE to be ready before you start serious viewings — you will see sellers, and agents expect you to have it lined up.
What the HFE letter tells you
Whether your household meets the eligibility conditions (at least one SC, under the S$14,000 monthly household income ceiling, no overlapping private-property ownership).
The exact CPF Housing Grants you qualify for (CPF Housing Grant, Enhanced CPF Housing Grant, Proximity Housing Grant).
The maximum HDB Concessionary Loan you can take, based on TDSR and MSR.
The minimum cash required at OTP and exercise stages.
Step 2: Shortlist Flats and Conduct Viewings
Once you have your HFE letter in hand, you can begin serious viewings. The HDB Resale Portal and third-party sites (PropertyGuru, 99.co, ourselves at LovelyHomes) let you filter by town, flat type, remaining lease and recent transacted price.
What to actually evaluate at a viewing
Remaining lease: Directly affects your maximum loan tenure and CPF usage. Anything under 60 years of remaining lease starts restricting grants and CPF usage significantly.
Condition of the flat: Look past the paint. Check ceilings for water marks (upstairs leaks), windows for water ingress, and door frames for termite damage.
Ethnic quota status: Your ethnic group must be under the block-level EIP cap. Ask the agent if the block is “open” for your group.
Noise and dust: Traffic, MRT, and construction noise. Visit twice — once at peak hour, once in the evening.
Ownership history: The agent should be able to confirm the number of previous owners and whether any structural alterations were made without HDB approval.
Step 3: Negotiate the Price and Receive the OTP
Once you and the seller agree on a price, the seller grants you the Option to Purchase (OTP). The option fee is fixed by HDB at S$1,000, paid on the spot. This buys you the exclusive right to purchase that flat at the agreed price for 21 calendar days.
The OTP is a legally binding document for the seller during those 21 days — they cannot sell to anyone else. But you, the buyer, can walk away by simply not exercising the option. You forfeit the S$1,000 but have no further obligation.
Cash-Over-Valuation (COV) in 2026
If the agreed price exceeds HDB’s official valuation, the gap must be paid in cash — never from CPF or loan. This is Cash-Over-Valuation, and it is firmly back on the table in 2026’s tight resale market. Budget for it if you are bidding on a popular estate or a high-floor unit. See our full COV guide for negotiation tactics.
Step 4: Exercise the OTP
Within the 21-day window, you exercise the OTP by paying the exercise fee. The option fee plus exercise fee cannot exceed S$5,000 combined — typically structured as S$1,000 option + S$4,000 exercise. At this point the sale becomes unconditional.
In the same 21 days, you should:
Engage a conveyancing lawyer (HDB’s in-house Legal & Claims Registry is a low-cost option for straightforward cases).
If taking a bank loan, finalise your loan offer and submit it for valuation.
Prepare the Buyer’s Stamp Duty (BSD) — due within 14 days of OTP exercise.
Step 5: Submit the Resale Application
Once the OTP is exercised, both parties log into the HDB Resale Portal and submit the resale application jointly. The portal walks you through the Resale Checklist, financial plan, and any declarations.
You will pay stamp duty, agree on the completion timeline, and nominate your solicitor. Your CPF refund to the seller, the loan disbursement and the final cash shortfall are all calculated at this point. HDB aims to process the resale application within eight weeks.
Typical fees at application stage
Resale application fee: S$80 (1-room / 2-room flats) or S$120 (3-room and above).
Buyer Stamp Duty (BSD): Graduated — 1% on first S$180k, 2% on next S$180k, 3% on next S$640k, 4% thereafter. On a S$600k resale, BSD comes to S$12,600. See our BSD guide for the full maths.
Legal fees: S$350–S$600 via HDB Legal, S$1,800–S$3,000 via a private conveyancing firm.
Step 6: Completion and Key Collection
About twelve to sixteen weeks after you first exercised the OTP, you will attend the completion appointment at HDB Hub. Both parties sign the legal transfer documents, CPF disbursements are triggered, your bank or HDB loan is drawn down, and you receive the keys.
From this moment, the flat is legally yours. Your MOP clock starts ticking from this date — see our MOP guide for what that means going forward.
Worked Example: Buying a S$620,000 4-Room Resale Flat
Let’s walk through a realistic 2026 purchase. A young couple, both Singapore Citizens and first-time buyers, buy a 4-room resale flat in Sengkang at S$620,000 — S$30,000 above HDB’s valuation of S$590,000.
Component
Amount
Purchase price
S$620,000
HDB valuation
S$590,000
COV (cash)
S$30,000
HDB loan @ 75% of valuation
S$442,500
Cash + CPF downpayment (25% of valuation)
S$147,500
Buyer Stamp Duty
S$13,200
Legal fees (HDB route)
~S$500
Minimum cash needed upfront
~S$60,000
The couple might qualify for an Enhanced CPF Housing Grant of up to S$80,000 depending on their combined income, which offsets a large chunk of the downpayment. See our CPF for property guide for how the grants flow into the purchase.
Common Mistakes That Delay or Kill the Deal
No HFE letter in hand: You cannot exercise an OTP without one. Plan at least three weeks of buffer before you start offering.
Underestimating COV: It has to come from cash savings, not CPF. Many deals collapse at OTP because buyers find their cash short.
Ignoring the ethnic quota: Your offer can be accepted, only to have HDB reject the resale application because the block is full for your group.
Not checking structural alterations: Unauthorised renovations (load-bearing wall removal, unpermitted window grilles) are the buyer’s problem after completion.
Valuation shock: If the valuation comes in below the purchase price, the cash shortfall must be covered by you — not CPF.
FAQ — HDB Resale Buying 2026
How long does the entire HDB resale process take?
Typically 12–16 weeks from OTP exercise to keys. Add another 2–6 weeks for your flat search, and 2 weeks for the HFE letter.
Can I use CPF to pay the option fee?
No. The S$1,000 option fee and the up-to-S$4,000 exercise fee both come from cash. CPF Ordinary Account funds only flow in at the resale-application stage.
What happens if I cannot exercise the OTP in time?
You forfeit the S$1,000 option fee. The seller is then free to grant the OTP to someone else.
Do I need a property agent to buy HDB resale?
No. HDB’s Resale Portal is designed to let buyers and sellers complete the process without an agent, though you are welcome to use one. Total agent commission on the buyer side is typically 1% of the purchase price.
Can I back out after I exercise the OTP?
Only with the seller’s agreement, and you would likely forfeit both the option and exercise fees (up to S$5,000). HDB does not have a “cooling-off” period for resale buyers once OTP is exercised.
Disclaimer: This is general guidance, not legal advice. Rules, fees and grant amounts change periodically — always verify with HDB directly before committing. Consult a qualified conveyancing lawyer for your specific purchase.
