How to Sell an HDB Flat in Singapore: Step-by-Step Guide
Fendy Lee

You've decided to sell. Now what? Most owners think the hard part is finding a buyer. It isn't. The hard part is the dates, the paperwork, and knowing how much money will actually reach your hands.
This guide shows how to sell an HDB flat in Singapore, from your first login on My Flat Dashboard to the day you hand over the keys. You'll see what each step involves, what it costs, and where sellers slip up. Fendy Lee, a Singapore property agent at Huttons, helps owners plan the sale around their next home, so we'll also cover what to settle before you list.
How to Sell an HDB Flat in Singapore
You sell an HDB flat by registering your Intent to Sell, finding a buyer, granting an Option to Purchase, filing the resale application together, and completing the sale at HDB. The formal part runs on fixed dates. Once HDB accepts your application, completion takes about eight weeks. The buyer search is the part nobody can fix.
Think of the sale as two clocks. The first starts when you list and stops when you grant the OTP, and its length depends on your price, your flat, and the market. The second starts at the OTP and follows the dates that HDB sets. That's why the HDB selling timeline feels longer to sellers who expect a single deadline.
Keep these limits in front of you before you start.
| What | The rule |
|---|---|
| Wait after registering the Intent to Sell | 7 days before you can grant an OTP |
| Option fee | $1 to $1,000, agreed with the buyer |
| OTP validity | 21 calendar days, expiring at 4pm on the 21st day |
| Option fee plus exercise fee | Together, no more than $5,000 |
| Second party's application | Within 7 calendar days of the first |
| Completion | About 8 weeks after HDB accepts the application |
| CPF refund | HDB refunds within 7 to 14 working days after completion |
Can You Sell Yet? Check Your MOP First
Before planning your sale, check whether your HDB flat has met the minimum occupation period (MOP). In general, Standard flats have a five-year MOP, while Plus and Prime flats have a ten-year MOP. You must also meet HDB's eligibility requirements to sell your flat.
You can check your MOP status through My HDBPage using your Singpass. If you have not met your MOP yet, use this time to review your finances and plan your next move. Our guide to selling your HDB MOP Flat in 2026? What You Must Know explains the rules and what to consider before making plans.
HDB Selling Process: Step-by-Step Guide
Here's how to sell an HDB flat in Singapore one stage at a time. Each stage has its own deadline, and a missed one can push the whole sale back by weeks.
Register Your Intent to Sell
Log in to My Flat Dashboard with Singpass and register your HDB Intent to Sell. HDB checks your eligibility straight away. It also shows your EIP and SPR quota status and recent transaction prices near your flat.
Here's the catch. You can't grant an OTP until seven days after you register. Register early, so the wait runs while you prepare the flat for viewings.
Price Your Flat Properly
Start with recent transactions for the same flat type in your block and street. Then compare your number with what a bank or HDB would value the flat at. Buyers taking a loan face a valuation, and an HDB valuation close to your asking price keeps the deal smooth.
If a buyer offers more than the valuation, the extra is called cash over valuation (COV). The buyer pays that gap in cash. It can lift your take-home, but it can also scare off buyers who haven't saved enough.
List the Flat and Show It
List the flat on property portals or through an agent, then arrange viewings. Keep the flat tidy and the details ready: lease start date, floor level, renovation, and any known issues.
Before you take a serious offer, ask the buyer to show how they'll pay. An HFE letter for an HDB loan or a bank's approval in principle tells you the buyer can proceed. Buyers who bring a trusted HDB buying agent in Singapore often arrive with this sorted, which saves everyone a week of chasing.
Grant the Option to Purchase
Once you've agreed on a price, you grant the option to purchase (OTP). You must use the HDB-prescribed form. Print only one copy, because each form has a unique serial number that goes into your resale application.
Fill in the option dates, flat address, resale price, and option fee. All co-owners sign, and you hand the OTP to the buyer. The buyer then has 21 calendar days to exercise it. You can't grant another OTP until this one expires, so choose the buyer carefully.
Agree on a Temporary Extension of Stay
Need more time to move into your next home? You may be able to arrange a temporary extension of stay with the buyer. Discuss this during negotiations and agree on the terms before proceeding. You must include the request in your HDB resale application, and the arrangement requires the buyer's agreement.
Submit the Resale Application
Once the buyer exercises the OTP, the resale application follows. Either of you can submit first. The other must follow within seven calendar days, and the application must carry the true resale price. Endorse the documents and pay the fees online. You can track the progress on the HDB resale portal or by SMS.
A quick word on the HDB resale application: it's the step where an honest price matters most. HDB checks the price you declare against the OTP, so keep them identical.
Get Ready for Handover
When HDB approves the application, it sets your completion date. Use the weeks before it to tidy up loose ends:
- Pay service and conservancy charges up to the completion date and get the Town Council's signed confirmation letter.
- Pay property tax up to the end of the year.
- Cancel GIRO arrangements for flat-related payments such as utilities and town council charges.
- Rectify any unauthorised renovation.
- Vacate the flat so the buyer can inspect it.
Attend the Completion Appointment
HDB sends the date and time by SMS and posts it on My Flat Dashboard. The HDB resale completion appointment is the only one that both you and the buyer must attend. You sign the transfer, hand over the keys, and settle the property tax with the buyer.
The date is the earliest HDB will complete, and HDB won't bring it forward. Bring your NRIC, the original OTP, the Town Council letter, and every key, including the spares. Your completion letter lists anything else.
You'll need a conveyancing lawyer for the paperwork. Compare HDB's own service with a private firm, and ask any HDB conveyancing lawyer you consider for a written fee quote first.
How Much Will You Take Home?
Knowing how to sell an HDB flat in Singapore is one thing. Knowing how much money you will actually keep is just as important. Your sale price is not the same as your cash proceeds. First, your outstanding housing loan must be settled. The CPF savings you used to buy and pay for the flat, including accrued interest, must also be refunded to your CPF account. Other outstanding payments and selling costs can reduce the amount you keep.
Your cash proceeds are the money left after the applicable deductions. If HDB handles your sale, the cash proceeds are released upon completion. For sellers who submit their resale application on or after 7 September 2026, HDB pays these proceeds electronically, generally by the next working day after completion. Different arrangements apply to earlier applications and sellers who appoint their own solicitors.
The CPF refund when selling an HDB flat is not a selling fee. The money goes back into your CPF account and can be used for eligible future housing payments or retained for retirement, subject to CPF rules. HDB states that the refund is generally credited between 7 and 14 days after completion.
Calculating Your Cash Proceeds
The following example uses illustrative figures for a 4-room HDB flat. Your actual proceeds will depend on your sale price, outstanding loan, CPF refund, and other expenses.
| Item | 4-room example |
|---|---|
| Sale price | $630,000 |
| Less: Outstanding HDB loan | $160,000 |
| Less: CPF refund, including accrued interest | $270,000 |
| Less: Agent fee (assumed 1.5% plus GST) | About $10,300 |
| Less: Legal and other costs (assumed) | $3,000 |
| Estimated cash remaining | About $186,700 |
These figures are for illustration only, and the costs are assumptions rather than fixed charges. The main takeaway is to calculate your expected proceeds before committing to your next property purchase. That way, you can plan your budget using a realistic estimate of the cash available to you.
The Cost of Selling an HDB Flat
Selling costs far less than buying, but it isn't free. Plan for these:
- Agent commission. It isn't set by law, and it's negotiable. A figure of around 1% to 2% plus GST is commonly quoted, so always agree to it in writing.
- Legal fees. They vary by firm, so get a quote before you appoint anyone.
- Resale application fees. HDB charges these online, and they're small compared with the rest.
- Service and conservancy charges and property tax. You pay these up to the completion date.
HDB's own guide suggests allowing roughly $3,000 for costs like legal fees and property tax, not counting any agent fee. That's a starting point, not a quote.
Sell With an Agent or On Your Own?
Selling your HDB flat yourself can save you the agent's commission, but you will need to handle the entire process. This includes setting the asking price, marketing your flat, arranging viewings, checking the buyer's progress, and meeting HDB deadlines. Missing an important deadline or making a mistake with the Option to Purchase (OTP) can delay the transaction.
Working with a property agent means paying a commission, but you can get help with pricing, marketing, buyer enquiries, and paperwork. An agent can also help you plan the sale around your next property purchase.
This is especially important if you plan to sell your HDB flat and buy another home. The timing of both transactions can affect when you need to move, how you manage your finances, and whether you have enough time to complete each step.
If you are planning to downsize or move to a different type of property, a rightsizing property agent in Singapore can help you consider your selling timeline alongside your next housing decision. Fendy Lee helps sellers plan their next move by looking at both the sale and purchase timelines before they list their flat.
Selling Your HDB Flat to Upgrade to a Condo?
If you plan to sell your HDB flat and move into a condo, the order of both transactions matters. Selling first helps you understand how much cash you will have available, while buying first may affect your loan eligibility and stamp duty obligations. You should also consider your moving timeline and whether you can manage both transactions comfortably.

Common Mistakes When You Sell an HDB Flat
Most mistakes in selling an HDB flat in Singapore come from missing a date, not from a bad price. These five are common.
- Registering late. The seven-day wait can hold up your OTP if you start too late.
- Taking a buyer without checking their financing. Ask for the HFE letter or a bank's approval in principle first.
- Granting an OTP too quickly. You can't grant another for 21 days, so a weak buyer can block better offers.
- Leaving handover tasks to the last week. Town Council letters, GIRO cancellations, and renovation fixes take time.
- Planning with the sale price. Your loan, CPF refund, and fees come out first.
Not sure how your sale lines up with your next move? Fendy Lee works as a rightsizing property agent in Singapore and can review your dates, your costs, and your cash before you list. Bring your HDB loan statement and your CPF refund figure, and the sale plan can be tested against your real numbers.
Conclusion: Know Your Dates Before You List
Selling your HDB flat becomes easier when you understand the process and plan ahead. Check your MOP, register your Intent to Sell at the right time, prepare your documents, and plan your move before completion.
Knowing how to sell an HDB flat in Singapore also means understanding how your sale affects your next property purchase. If you plan to upgrade to a condo, Fendy Lee can help you review your timeline and understand the key steps before you list your flat.

FAQs
How to Sell an HDB Flat in Singapore Without an Agent?
Register your Intent to Sell, list the flat yourself, grant the OTP, and submit the resale application with your buyer. Everything else follows the same steps and deadlines as an agent-led sale. The main extra work is vetting the buyer's financing and tracking every date yourself.
Can I sell before my MOP ends?
Generally, no. You must finish the MOP and own only one HDB flat to be eligible. If special circumstances apply, such as a family or financial emergency, speak to HDB directly instead of relying on a general guide.
Can I accept a better offer while my OTP is running?
No. You can't grant another OTP until the first one expires, which happens at 4pm on the 21st calendar day. If the buyer doesn't exercise the OTP by then, it lapses, and you're free to grant a new one.
Can I stay in the flat after I sell it?
Sometimes. You can arrange to stay on for a short period with the buyer's agreement and request it in the resale application. Without that, you must vacate before the completion appointment.
What if I made renovations without approval?
Fix them before completion. HDB expects unauthorised renovation to be rectified, so build that time into your plan rather than leaving it for the final week.
Who pays the property tax and service charges?
You do, up to the completion date for service and conservancy charges, and up to the end of the year for property tax. At the completion appointment, you and the buyer apportion the property tax for the part of the year each of you owned the flat.
Can I sell my flat and buy a condo at the same time?
Yes, once your MOP is over, the order of the two deals changes your stamp duty and loan limits. Work out your timing before you list, and use the planner and condo guide above to compare both routes.
