Step-by-step guide to selling your HDB flat in Singapore — from checking your eligibility to completing the resale transaction, including CPF refund rules and costs involved.
Can You Sell Your HDB Flat? Checking Eligibility
Before you list your flat for sale, you need to confirm you're eligible to sell. The most important requirement is the Minimum Occupation Period (MOP).
Minimum Occupation Period (MOP)
The MOP is the minimum period you must physically occupy your flat before you can sell it on the open market:
Standard BTO/DBSS/EC flats: 5 years from key collectionResale flats bought with CPF Housing Grant: 5 years from date of resale completionResale flats bought without grants: No MOP (you can sell anytime)SERS replacement flats: 5 years or 7 years depending on the schemeImportant: The MOP is calculated from the date of key collection, not the date you signed the Agreement for Lease or moved in. All owners listed on the flat must have occupied the flat during the entire MOP period.
Other Eligibility Conditions
Ethnic Integration Policy (EIP): Your buyer must meet the ethnic quota for your blockSingapore Permanent Resident (SPR) Quota: If selling to PRs, the block quota must not be exceededOutstanding loans: All HDB loans must be repayable from the sale proceedsOwnership of other property: If you bought a private property during MOP, you must sell the HDB within 6 months of the private property purchaseStep 1: Engage a Property Agent (Optional but Recommended)
While you can sell your HDB flat on your own, engaging a professional property agent offers significant advantages:
Why Use an Agent
Market expertise — agents know the current market value and comparable transactions in your areaMarketing reach — agents have access to property portals (PropertyGuru, 99.co, EdgeProp) and buyer networksNegotiation skills — experienced agents can negotiate the best price for your flatPaperwork handling — the resale process involves multiple forms, submissions, and deadlinesViewing management — agents handle scheduling, conducting viewings, and following up with interested buyersAgent Commission
The standard agent commission for selling an HDB flat is 2% of the sale price (plus GST). This is negotiable, but 2% is the market norm.
For a flat sold at $500,000, the commission would be approximately $10,000 + GST = $10,900.
Tip: Always engage a CEA-registered agent. You can verify an agent's registration on the [CEA Public Register](https://www.cea.gov.sg/aceas/public-register).
Step 2: Determine Your Flat's Market Value
Getting the right price is crucial — price too high and your flat sits on the market; price too low and you leave money on the table.
Methods to Assess Value
1. HDB Resale Flat Prices (data.gov.sg)
Free access to all past HDB resale transactionsFilter by town, flat type, storey range, and dateThe most reliable source of comparable data2. Recent Comparable Transactions
Look at sales in your block or nearby blocks within the last 3–6 monthsAdjust for floor level, facing, condition, and remaining lease3. Professional Valuation
A bank-appointed valuer will provide a formal valuationThis is required when the buyer applies for a bank loanThe valuation affects the buyer's loan quantumPricing Strategy
Set a realistic asking price based on recent comparablesFactor in your flat's unique selling points (renovations, high floor, unblocked view)Be prepared to negotiate — most HDB sales involve some price negotiationMonitor market feedback — if you're not getting viewings, your price may be too highStep 3: Prepare Your Flat for Sale
First impressions matter. A well-presented flat sells faster and at a better price.
Essential Preparation
Declutter every room — less is more during viewingsDeep clean the entire flat, including windows and common areasFix minor defects — leaking taps, chipped tiles, faulty lightsRepaint if walls are scuffed or have strong colours (neutral tones sell best)Stage the flat — arrange furniture to maximise the sense of spaceWhat NOT to Do
Don't spend $30,000 on renovations just before selling — you likely won't recoup the costDon't hide defects — buyers will discover them during the inspectionDon't leave personal items (photos, religious items) prominently displayed during viewingsStep 4: Market Your Flat and Conduct Viewings
Marketing Channels
Your agent will typically list your flat on:
PropertyGuru — Singapore's largest property portal99.co — popular alternative portalEdgeProp — growing platform with strong data featuresSocial media — Facebook groups, InstagramAgent's personal network — often the fastest route to a buyerDuring Viewings
Ensure the flat is clean, well-lit, and ventilatedLet your agent handle the viewing — they know what buyers look forBe flexible with timing — weekend and evening viewings attract the most buyersKeep pets secured and minimise noise distractionsStep 5: Negotiate and Grant the Option to Purchase (OTP)
When a buyer makes an offer you're willing to accept:
The OTP Process
Agree on the sale price — negotiate via your agentsRegister your Intent to Sell on the HDB Resale Portal (if not done earlier)Grant the OTP to the buyer — this is the formal offer documentBuyer pays you an Option Fee — typically $1,000 (up to $1,000 as per HDB guidelines)The OTP is valid for 21 calendar days — during this period, the buyer decides whether to exercise the OTPIf the buyer exercises the OTP, they pay you an additional Option Exercise Fee — typically 4% of the sale price minus the $1,000 already paidImportant OTP Notes
You cannot grant OTPs to multiple buyers simultaneouslyOnce the buyer exercises the OTP, both parties are legally committed to the transactionIf the buyer does not exercise the OTP within 21 days, it lapses and you keep the $1,000 Option FeeStep 6: Submit the Resale Application
After the buyer exercises the OTP:
Timeline and Process
Both parties submit the resale application on the HDB Resale PortalBuyer's portion must be submitted within 7 days of OTP exerciseHDB processes the application — typically takes 8 weeksHDB schedules a completion appointment — you'll receive the date approximately 2 weeks before completionCompletion appointment at HDB Hub — keys are handed over and sale is finalisedDocuments Required
NRIC of all ownersOTP (signed and exercised)Proof of address for correspondenceLatest CPF statement (to confirm refund amounts)Existing loan redemption letter (if applicable)Step 7: CPF Refund Rules — What You Need to Know
This is the part that catches many sellers off guard. When you sell your HDB flat, you must refund to your CPF Ordinary Account (OA):
What Gets Refunded
Principal amount — every dollar of CPF you used for the flat purchase (downpayment, stamp duty, and monthly mortgage payments from CPF)Accrued interest — interest that your CPF money would have earned if it had stayed in your OA (currently 2.5% per annum, compounded)Example Calculation
| Item | Amount |
|------|--------|
| CPF used for downpayment | $50,000 |
| CPF used for monthly mortgage (over 15 years) | $180,000 |
| CPF used for stamp duties | $5,000 |
| Total CPF principal | $235,000 |
| Accrued interest (2.5% p.a. over 15 years) | ~$65,000 |
| Total CPF refund required | ~$300,000 |
Important Points
The CPF refund is mandatory — it happens automatically from the sale proceedsIf your sale price doesn't cover the CPF refund, you don't have to top up the shortfall from cashThe refunded amount goes back to your CPF OA and can be used for your next property purchaseAny cash proceeds (sale price minus CPF refund minus outstanding loan minus costs) are yours to keepCosts of Selling Your HDB Flat
