Quick answer
Selling an HDB flat has nine steps: check you are allowed to sell, work out your proceeds, register an Intent to Sell on the HDB Resale Portal and wait 7 days, price it, market it, grant an Option to Purchase, let the buyer exercise it within 21 days, submit the resale application, and complete about 8 weeks after HDB accepts. From the day a buyer signs the option to the day you hand over keys is roughly three months. Finding that buyer is the part that varies: across my 77 HDB sales, 3 in 10 took under a month and 4 in 10 took three months or more.
The paperwork is the same for every flat. What differs is what goes wrong at each step, and that is what this guide is about.
I have sold 77 HDB flats across 22 towns, and the process below has not changed much in that time. What has changed is how easy it is to get a step slightly wrong and lose three weeks. So under each step I have put the thing I most often see go wrong, because that is the part HDB's own guide will not tell you.
1Check that you can sell
Three things decide whether you can sell at all, and a fourth decides whether you should.
- Minimum Occupation Period. Five years for a standard flat, counted from key collection, not from the booking date. Flats bought under the Plus and Prime classification (launches from October 2024) carry a 10-year MOP, and Prime Location flats before that also carry 10 years. Time spent renting out the whole flat or living overseas does not count.
- Ethnic Integration Policy and SPR quota. Your block and neighbourhood have quotas by ethnic group, and a separate quota for non-Malaysian Singapore PR households. If your buyer's profile would breach the quota, HDB will not approve the sale. You can check this on the Resale Portal before you list; it changes who can buy your flat and therefore your price.
- Outstanding loan and CPF. Whether your sale price covers the loan balance plus the CPF you used, with accrued interest. If it does not, you have a negative sale and need cash to top up. Step 2 covers this.
- Seller's Stamp Duty. If you bought after 4 July 2025 and sell within four years (three years for earlier purchases), you pay SSD on a sliding scale. Most HDB sellers are past this because of the MOP, but upgraders who bought a second flat quickly get caught.
2Work out what you will walk away with
Do this before you talk to any agent, because it changes what price you need and whether you can buy your next home before selling this one. The sale price is not your money. From it, HDB and CPF deduct, in this order: the outstanding loan, the CPF principal you used plus accrued interest at 2.5%, any SSD, and the agent's fee. What is left is cash. If the CPF refund is larger than the price minus the loan, the shortfall comes from your pocket.
The sale proceeds calculator does this arithmetic with the agent's fee at 2% plus GST and at my fixed fee side by side. Have your latest CPF housing statement and loan statement open when you use it.
3Register your Intent to Sell, then wait 7 days
Log in to the HDB Resale Portal with Singpass and register an Intent to Sell. HDB checks your eligibility, shows you the ethnic quota position for your block, and tells you whether you must sell under any conditions. The Intent is valid for 12 months. From the day you register, there is a 7-day cooling period during which you cannot grant an Option to Purchase to anyone. HDB introduced this so sellers have a week to read the rules before they commit; in practice it means the Intent should be registered before you list, not after you find a buyer.
4Price the flat
This is where the money is won or lost, and it is the step agents spend the least time on. The method is the same every time: pull the last twelve months of resale transactions for your block and the blocks around it, same flat type, on the HDB portal. Adjust for floor, facing, renovation and remaining lease. Then look at what is currently listed near you at a similar price, because those are your competition this month, not last year's transactions.
Two numbers matter. The valuation HDB will assign after the option is granted, which is usually close to recent transactions, and the price above it that a buyer must pay in cash, the so-called cash over valuation. Buyers with limited cash cannot go far above valuation, however much they like the flat. So a price $30,000 above the likely valuation shrinks your buyer pool to those with $30,000 spare, and that is why overpriced flats sit.
5Market it and run viewings
Photos, a floor plan, and a listing on the portals are the minimum. What actually moves a flat in 2026 is video: a home tour that a buyer watches on their phone before they decide whether to visit. My listings get a walkthrough on TikTok and YouTube because that is where the buyers are looking, and a buyer who has already watched the video arrives at the viewing half-decided.
Before a viewing, screen the buyer. Every buyer needs a valid HDB Flat Eligibility (HFE) letter before you can grant them an option, so ask whether they have one, what loan it approves, and how much cash they have above that. A buyer without an HFE letter is a viewing, not a buyer.
6Negotiate and grant the Option to Purchase
When a buyer makes an offer you accept, you grant them an Option to Purchase on HDB's prescribed form, through the portal. The rules are fixed:
- The buyer pays an option fee of up to $1,000. In return you cannot grant an option to anyone else for 21 calendar days.
- The buyer must submit a Request for Value to HDB by the next working day after the option date, paying $120. HDB's valuation decides how much loan and CPF the buyer can use.
- If the buyer proceeds, they exercise the option within the 21 days and pay the exercise fee. The option fee and exercise fee together cannot exceed $5,000. If they walk away, you keep the option fee and start again.
Negotiation happens before the option is granted, not after. Once it is signed, the price is fixed, and the only question is whether the buyer exercises.
7The buyer exercises, both sides apply to HDB
After the buyer exercises, both of you submit your portions of the resale application on the portal. The first party to submit starts a clock: the other side must submit within 7 calendar days or the application is cancelled. Each side pays an administrative fee of $80 for a 3-room or larger flat ($40 for 1- and 2-room). You will choose who handles the conveyancing; most sellers use HDB's own solicitors, which is the cheaper route, and the fee is deducted at completion.
HDB then checks everything: eligibility, the quota, the buyer's financing, the valuation. When it is satisfied it issues an acceptance, and that acceptance date sets the completion date.
8HDB acceptance to completion
Completion is scheduled about 8 weeks after HDB's acceptance. In those weeks, HDB's solicitors prepare the documents, you clear the outstanding loan and CPF refund from the proceeds, and you move out. If you need to stay on after completion because your next home is not ready, you can ask the buyer for a temporary extension of stay of up to 3 months; it has to be agreed and included in the resale application, with a small HDB admin fee, and the buyer can say no.
9Completion day and after
On the completion appointment, both parties (or their solicitors) sign, the buyer's funds are released, and HDB disburses in the order from step 2: loan, CPF refund with interest, then the balance to you. You hand over the keys, the flat has to be vacant and in the condition the buyer saw it, and the sale is done. The CPF refund lands in your Ordinary Account and can be used again for your next purchase.
How long does the whole thing take?
| Stage | Typical time | Who controls it |
|---|---|---|
| Intent to Sell → first day you can grant an option | 7 days | HDB rule |
| Listing → a buyer signs the option | 1 to 3+ months | Price and the market |
| Option granted → exercised | up to 21 days | Buyer |
| Exercised → resale application → HDB acceptance | 2 to 4 weeks | Both sides, then HDB |
| HDB acceptance → completion | about 8 weeks | HDB |
Across my 77 HDB sales, 30% found a buyer within 30 days, 58% within 3 months, 42% took 3 months or more. The breakdown is in the fixed fee vs 2% guide.
So from option to keys is about three months if nothing slips. From listing to keys, four to six months is a fair planning assumption for a well-priced flat.
What I would do if I were selling my own flat
1. Run the proceeds calculator with real CPF and loan statements before anything else. If the number is bad, better to know in week zero.
2. Register the Intent to Sell the same day. The 7 days are free while you take photos.
3. Price off transactions, not off hope. Then decide the lowest price you would accept before the first viewing, so an offer on day three does not catch you unprepared.
4. Screen every buyer for an HFE letter and cash above valuation before they view. It halves the viewings and doubles the offers.
Frequently asked questions
Can I sell my HDB flat without an agent?
Yes. The Resale Portal is built for owners to transact directly, and HDB's fees are small. You then do the pricing, marketing, screening and negotiation yourself. My guides page will have a separate guide on when that makes sense.
Do I need the buyer to have an HFE letter?
Yes. Since 2023 a buyer must hold a valid HDB Flat Eligibility letter before you can grant them an Option to Purchase. Ask to see it before the viewing.
What is cash over valuation?
The difference between the agreed price and HDB's valuation. Loans and CPF are capped at the valuation, so the buyer pays the difference in cash. It is why an overpriced flat attracts viewings but not offers.
Can I sell before my MOP ends?
Only in exceptional circumstances with HDB's approval, such as divorce or financial hardship, and usually with conditions. For a standard flat it is 5 years from key collection; 10 years for Plus and Prime flats.
How much are the HDB fees to sell?
$80 resale application fee for a 3-room or larger flat, plus conveyancing if HDB's solicitors act for you, deducted at completion. The buyer pays the $120 valuation fee. The agent's fee is the large item; see the commission guide.
Can I stay in the flat after completion?
Up to 3 months, if the buyer agrees and it is included in the resale application before HDB accepts it. It cannot be added afterwards.
