Quick answer
Selling an HDB flat takes roughly two to four months: register an Intent to Sell, market the flat, grant an Option to Purchase to your buyer, submit the resale application, then complete about eight weeks after HDB accepts it. Your proceeds repay the loan and refund CPF with accrued interest first — the rest is cash.
Key takeaways
- You can only sell after your Minimum Occupation Period (5 years for most flats; 10 for PLH flats).
- The Intent to Sell on the HDB Flat Portal is mandatory and must sit for 7 days before you can grant an OTP.
- Completion happens about 8 weeks after HDB accepts the resale application.
- Proceeds go: outstanding loan → CPF refund with accrued interest → cash to you.
- The first 2–3 weeks of marketing attract the most buyer attention — price right from day one.
The process, step by step
1. Check eligibility and register your Intent to Sell
Confirm your MOP has passed, then register an Intent to Sell on the HDB Flat Portal. It's valid for 12 months, and HDB requires it to be at least 7 days old before you grant any Option to Purchase. The portal also shows your buyers' eligibility requirements and any Ethnic Integration Policy quota limits for your block — check these early, because they shape your realistic buyer pool.
2. Get the numbers straight
Pull your outstanding loan balance and your CPF usage plus accrued interest. Then look at transacted prices — not asking prices — for your flat type in your block and immediate neighbours over the past six months. HDB publishes resale transaction data; this is the evidence a serious pricing decision rests on.
3. Prepare and market the flat
Declutter, brighten, and fix small visible defects. Then photograph properly and list. Expect the heaviest enquiry volume in the first two to three weeks — this is your flat's moment of maximum leverage.
4. Viewings, negotiation, OTP
When you accept an offer, you grant the buyer an Option to Purchase for an option fee (up to $1,000 combined with the deposit rules). The buyer has 21 days to exercise it. Once exercised, both sides submit the resale application to HDB.
5. Resale application to completion
HDB verifies both parties' eligibility and accepts the application; the completion appointment follows around eight weeks later. At completion, ownership transfers, keys are handed over, the loan is discharged, CPF is refunded, and the balance is paid to you.
What selling costs
| Item | Typical range | Note |
|---|---|---|
| Agent commission | Agreed in writing | Typically a percentage of price; always confirmed before listing |
| HDB resale application fee | Modest fixed fee | Per HDB's current schedule |
| Legal/conveyancing fees | Varies by provider | Lower if using HDB's lawyers where eligible |
| CPF refund with accrued interest | Depends on usage | Not a cost — but reduces cash proceeds |
| Upgrading levy / resale levy | Situational | Applies in specific second-subsidised-flat scenarios — verify yours with HDB |

A worked scenario
A couple in Bukit Batok (composite case, details changed) listed their 4-room flat at $655,000 against my evidence-based estimate of $625,000, reasoning "we can always come down". Six quiet weeks later, the listing had gone stale — agents and buyers had mentally filed it as overpriced. We relaunched at $618,000 with new photos, drew three competing viewings in ten days, and closed at $628,000. The lesson: the market told us the price was wrong within three weeks; listening earlier would have saved six.
Common mistakes
- Pricing on hope, not transactions. The first weeks are irreplaceable; a stale listing costs more than an honest price.
- Granting an OTP before the Intent to Sell is 7 days old. The OTP would be invalid — a genuine procedural trap.
- Forgetting the CPF refund. Plan around cash proceeds, not the headline price.
- Not agreeing an extension of stay when upgrading. Up to three months of breathing room, wasted because no one raised it.
- Empty-flat viewings with the lights off. A ten-dollar problem creating five-figure damage.
Frequently asked questions
No — proceeds first clear your outstanding loan, then refund your CPF with accrued interest to your Ordinary Account. The remainder is cash. If you're upgrading, the refunded CPF is usable again for the next home once credited.
Yes — HDB's process supports DIY sellers, and for some people it's the right call. What you're buying with an agent is pricing judgement, buyer screening and negotiation. If you want an honest view on whether your situation needs one, ask me; "you can DIY this" is an answer I do give.
Then the sale is half of a bigger plan — sequencing, ABSD and CPF timing all interact. Read the HDB-to-condo upgrading guide next, or go straight to an upgrading review.
