Selling your HDB flat is one of the most significant financial decisions you will make as a Singapore homeowner. For many families, the HDB flat is not just a home — it is the foundation of their wealth and the launchpad for their next chapter.
But the process of selling an HDB in Singapore is more layered than most people expect. Miss a step, get the sequence wrong, or sell without a clear plan for what comes next, and you risk financial penalties, a compressed timeline, or an upgrade that simply does not work out the way you hoped.
This guide walks you through exactly how to sell your HDB flat in Singapore — step by step — so you move with confidence, not guesswork.
Step 1: Confirm Your Minimum Occupation Period (MOP)
Before anything else, check whether you have fulfilled your Minimum Occupation Period (MOP). For most HDB flats purchased directly from HDB, the MOP is 5 years from the date you collect your keys — not from the date of purchase. For Plus and Prime flats, the MOP is 10 years.
You cannot sell your flat on the open resale market until MOP is met. Log into the HDB Resale Portal with your Singpass to check your eligibility date. If you are approaching MOP, use this window to plan — not to rush.
Step 2: Plan Your Next Move Before You List
This is the step most DIY sellers skip — and the one that matters most.
Before you put your flat on the market, you need a clear answer to: what am I buying next, and can I actually afford it? This means checking your CPF balances, understanding your loan eligibility post-sale, factoring in Additional Buyer's Stamp Duty (ABSD) if applicable, and knowing how long you can realistically bridge between selling and moving.
Selling without a forward plan is the single biggest mistake HDB upgraders make. Get this locked in first.
Step 3: Register Your Intent to Sell
To officially kickstart your selling journey, you must register your Intent to Sell on the HDB Resale Portal. This step is mandatory and valid for 12 months.
Registering your Intent to Sell provides you with an instant assessment of your eligibility to sell, the Ethnic Integration Policy (EIP) and Singapore Permanent Resident (SPR) quota for your block, and recent transacted prices of nearby flats.
Crucially, there is a mandatory 7-day cooling-off period after registering your Intent to Sell before you can grant an Option to Purchase (OTP) to a buyer. Do not wait until you find a buyer to register, or you might lose them to this administrative delay.
Step 4: Research Comparable Transactions (Comps)
Before you set an asking price or engage anyone, spend 30 minutes doing your own homework. HDB publishes every resale transaction on their website — free, public, and updated regularly. This data is your most reliable pricing reference.
Go to HDB Resale Flat Prices (accessible at www.hdb.gov.sg or via the HDB Map Services portal). Search for transactions within your block first, then widen to your street, then your estate. Filter by flat type and look at transactions from the last 3–6 months — anything older starts losing relevance in an active market.
When comparing, pay attention to floor level, facing, and lease commencement date. A unit on the 15th floor with an unblocked view will transact meaningfully higher than a 3rd floor unit in the same block, even with identical square footage. These nuances matter when you are deciding whether to price at, above, or slightly below recent transactions.
What you are building here is a realistic price range — not a fixed number, but a defensible bracket you can anchor your asking price within. Sellers who skip this step either overprice and stagnate, or underprice and leave tens of thousands on the table.
A good rule of thumb: if the last 3 comparable transactions in your block fall between $550,000 and $580,000, your realistic asking range is $570,000 to $595,000 depending on your unit's attributes. Price with evidence, not emotion.
Step 5: List Your Flat and Set Your Asking Price
You can list your flat yourself via the HDB Flat Portal or engage a licensed agent. If going DIY, ensure your listing includes quality photographs, accurate floor area, and a competitive asking price benchmarked against the comparable transactions you researched in Step 4.
Pricing strategy matters. Overpricing extends your time on market and signals desperation when you eventually reduce. Underpricing leaves money on the table. Aim to price within 2–3% of recent comparable transactions and be prepared to negotiate.
Step 6: Grant an Option to Purchase (OTP)
When a buyer is ready to commit, you grant them an Option to Purchase (OTP). The buyer pays a 1% option fee (capped at $1,000 for HDB) and has 21 calendar days to decide whether to exercise the option by paying a further 4% deposit.
During this window, you cannot accept offers from other buyers. Once the OTP is exercised, both parties are legally committed to the transaction. Review the OTP carefully — ensure the agreed price, completion timeline, and any inclusions are clearly stated.
Step 7: Complete the HDB Resale Process
Once the OTP is exercised, both buyer and seller submit their portions of the resale application through the HDB Flat Portal within 7 days of each other.
HDB will assess the application and, once accepted, both parties must endorse the resale documents online. During this step, you will confirm details such as CPF usage, housing loan arrangements, and the legal documents required for the transaction. This online endorsement replaces the previous First Appointment.
HDB will then schedule a Resale Completion Appointment, typically about 8 weeks after the resale application is accepted. During this appointment, legal ownership of the flat is transferred, the keys are handed over to the buyer, sale proceeds are disbursed to the seller, and the seller's CPF principal plus accrued interest is refunded to the CPF Ordinary Account.
Prepare your NRIC and any supporting documents requested by HDB before the completion appointment. If there is an outstanding HDB loan on the flat, HDB will automatically redeem it from the sale proceeds.
Step 8: Plan Your Proceeds and Execute Your Next Purchase
After completion, you will receive your net cash proceeds — that is your sale price minus outstanding mortgage, CPF refund (principal plus accrued interest), legal fees, and agent commission if applicable.
This is the moment your upgrade plan must be ready to execute. Whether you are moving into a new launch condo, a resale private property, or an executive condominium, your timeline, budget, and loan eligibility should already be mapped out before you reach this step — not after.
Many sellers reach this point cash-rich but plan-poor. That gap is expensive.
Common Mistakes HDB Sellers Make
Even well-prepared homeowners trip up at these points:
Selling without confirming upgrade eligibility first. ABSD rules, CPF usage limits, and loan-to-value ratios all affect what you can buy next. Discovering you cannot afford your target property after you have already sold is a painful and avoidable situation.
Relying on portal estimates instead of actual transaction data. Online estimates are averages — they do not account for your specific unit's floor level, facing, or lease remaining. Use HDB's own resale transaction database for an accurate read on your flat's market value.
Not planning for the gap period. Between handing over your HDB and moving into your next home, you may need temporary housing. This costs money and creates pressure. Plan for it early, not at the last minute.
