Selling Your HDB Flat in 2026: The Whole Process, With Real Numbers
Valuation, timeline, CPF refund, costs and commission, dated for 2026 rules. By the end you'll know what your sale should look like, and you can get a free valuation with the comparables shown.
Most sellers I meet have the same three worries, usually in this order.
The first is the price. You've checked your flat's value online a few times and got a different number each time. A neighbour's flat sold for a figure that sounds too good, and another one down the road has been sitting on the portals for four months. Somewhere between those two is your number, and pricing wrong in either direction costs you. Too high and the listing goes stale; buyers skip stale listings without ever viewing. Too low and you've handed the next owner a discount for no reason.
The second is timing. If you're selling to buy again, everything connects: the ABSD remission clock, the CPF refund, where you live in between. Sell first or buy first is a real decision with real money on both sides, and it deserves more than a coin flip.
The third is trust. Some agents quote a high valuation to win the listing, then spend the next three months calling you with reasons to drop the price. You have no way to tell who's doing that until it's happening.
The number first
How I Price Your Flat
I start with one number, and I show you where it comes from.
Your valuation is built from recent transactions in your block and your town, adjusted for floor, facing, renovation and remaining lease. Not asking prices. Not a tool estimate. Transacted prices, the same ones buyers' banks will use when they value your flat. You get the comparables in writing, so if you think my number is wrong you can see exactly which sales I used and argue with me. Sellers sometimes do, and sometimes they're right about their own renovation. The number gets better for it.
Then we agree on a plan in writing: the listing price, the floor we'll accept, the timeline, and what happens if the first two weeks are quiet. After that I run the marketing, the viewings and the negotiation, and you get a written update every week whether there's news or not.

Step by step
The Selling Process, Step by Step
From decision to completion, a typical HDB resale in 2026 runs three to five months. Here's the shape of it.
Step 1 — Valuation and pricing (Week 0–1)
I visit, look at what the photos will see, and pull the last six months of transactions for your block and town. We settle three figures in writing: the asking price, the expected selling range, and the walk-away floor. You approve all three before anything is advertised. If you're a second-timer, this is also when we check your resale levy position, because it changes your net proceeds.
Step 2 — Paperwork and preparation (Week 1–2)
You register your Intent to Sell on the HDB portal. There's a 7-day cooling period before you can grant an Option to Purchase, and we use that week properly: professional photography, floor plan, and listing copy that you approve before it goes live. Declutter advice is free and blunt. The flats that photograph well get the viewings; that's most of the game.
Step 3 — Marketing (Week 2 onwards)
Your flat goes on PropertyGuru, 99.co and the PropNex network, which reaches buyers the portals alone don't: co-broke agents with clients already looking in your town. In 2026, about 13,480 flats reach MOP this year, with big waves in Punggol and Tampines. If that's your competition, your listing needs to be sharper than theirs, and the pricing has to respect the extra supply. That conversation happens in Week 0, not Week 8.
Step 4 — Viewings (usually Weeks 2–6)
I run viewings around your family's routine, weekends and evenings, and I'm there for every one. Well-priced flats in good locations typically see steady viewing traffic in the first fortnight. If traffic is thin, you'll hear it from me in the weekly update with the data behind it and options, not excuses.
Step 5 — Offers, negotiation and the OTP
When an offer comes in, you hear the full picture: the price, the buyer's HFE status, their timeline, and any conditions. No offer is accepted without your explicit say.
Once you accept, you grant the buyer an Option to Purchase. The option fee is up to $1,000, the buyer has 21 calendar days to exercise, and the option plus exercise deposit together cannot exceed $5,000. After exercise, the deal is binding on both sides.
Step 6 — Resale application and completion (about 8–12 weeks from OTP)
Both parties submit the resale application through the HDB portal. HDB's processing and the completion appointment follow, and the whole stretch from OTP to completion typically runs 8 to 12 weeks. I track every deadline with your lawyer or HDB's process so nothing lapses. You hand over the keys with vacant possession, and the proceeds land after the CPF refund is settled.
Net proceeds
The Money Nobody Warns You About
The sale price is not what lands in your bank account. Three things come out of it, and you should know all three before you list.
CPF refund with accrued interest. Every dollar of CPF you used on the flat, plus the interest it would have earned, goes back into your CPF accounts first. On a typical upgrade this is the biggest surprise in the whole process, and the reason "sold for $700,000" doesn't mean "$700,000 in cash." Full worked example here: CPF refund and accrued interest, explained.
Resale levy, if you're a second-timer. If you've bought a subsidised flat before and are buying another, the levy runs from $15,000 to $50,000 depending on flat type. Check it before you price, not after you sell. Details: HDB resale levy guide.
Commission. The market norm for selling an HDB flat is 1–2% of the sale price. I publish exactly how commission works, what it covers, and what different agents charge in this guide: property agent commission in Singapore. My own rate is 1–2%, agreed in writing before we start, and it doesn't change mid-sale.
Upgrading
Selling to Upgrade? Read This Before You Sequence Anything
It depends on your cash buffer and your nerve. Sell first and you know your exact budget, but you may need interim housing. Buy first and you keep one move, but if you're married and buying your second property, the ABSD remission clock gives you six months to sell your flat or the remission is gone. That clock has burned more upgraders than any other rule in Singapore property.
Cash needed upfront
Risk
Most upgrader families should sell first unless they can carry two properties comfortably for 6 months.
I've mapped both routes with the real timelines, the CPF refund maths and a worked example here: selling your HDB to upgrade to a condo, and the underlying rules here: the ABSD remission rules. Tell me your situation and I'll tell you which side the risk sits on for you.
The DIY question
Can You Do It Without an Agent?
Yes, and some sellers do it well. If you have time for viewings, comfort with negotiation, and patience for HDB paperwork, DIY is a legitimate route. Where DIY sellers most often lose money isn't the commission maths; it's pricing off asking prices and negotiating against themselves.
I've written an honest comparison, including the cases where doing it yourself genuinely makes sense: selling your HDB without an agent. If you read it and still want to do it yourself, the valuation here is free either way.

Working standards
What You Can Hold Me To
These are my working standards on every sale. They're in writing, and if I miss one, I expect you to say so.
- Your valuation comes with comparables. Every number I quote is backed by transacted sales you can check. If I can't defend a price, I won't propose it.
- Nothing is advertised without your approval. Photos, copy and asking price go live only after you've signed them off.
- A written update every week. Viewings held, feedback heard, offers received, portal numbers. Even when the honest update is "nothing happened this week."
- No quiet price-chipping. If I believe a price adjustment is right, you get the reasons and the data in writing, and the decision stays yours. I don't win listings with a high number and spend months walking it back.
- Every offer reaches you. Full details, promptly, with my read of the buyer's position. You decide, always.
- I reply within the hour, 9am–9pm. Selling a home is stressful enough without chasing your agent.
- If I'm not the right fit, I'll say so. If your flat needs something I don't do well, you'll hear that before you sign anything, along with my honest suggestion.

Questions
The Questions Every Seller Asks
Three to five months is typical. Marketing and viewings usually run 2 to 6 weeks for a well-priced flat, then the OTP exercise window is 21 days, and completion follows about 8 to 12 weeks after the OTP is granted. The full breakdown is on the timeline page.
Budget for agent commission (market norm is 1–2% of the sale price; my rate is 1–2%), legal or HDB processing fees, and any resale levy if you're a second-timer ($15,000–$50,000). Your CPF refund with accrued interest also comes out of the proceeds before cash reaches you.
All CPF principal used for the flat, plus accrued interest, is refunded to your CPF Ordinary Account from the sale proceeds. If the sale price doesn't cover the refund, you generally don't need to top up the shortfall in cash, provided the flat sold at or above market value. Full worked example: CPF refund guide.
Generally no. The Minimum Occupation Period is five years for most flats (ten for Prime Location Housing), counted from key collection. There are narrow exceptions, but for almost all sellers the MOP date is a hard gate. Current rules: HDB MOP rules 2026.
Sell first if you want certainty on budget and no ABSD exposure; buy first only if you can comfortably manage the ABSD remission clock, which requires selling your flat within six months of buying the next property (for married couples buying their second home). The decision depends on your cash buffer and risk tolerance, and I map both routes in the upgrade guide.
No. Price is one term among several. A buyer with HFE approval in hand, a clean timeline and no conditions at $5,000 less often beats a higher, shakier offer. You decide on the full picture, and no offer is ever accepted without your explicit approval.
