Selling your HDB flat is one of the biggest financial decisions you'll make. Whether you're upgrading to a condo, rightsizing for retirement, or simply ready for a change — this guide walks you through the entire process step by step, so you know exactly what to expect at every stage.
1. Check Your Eligibility to Sell
Before anything else, confirm you're allowed to sell. HDB has a Minimum Occupation Period (MOP) — typically 5 years from the date you collected your keys. You cannot sell before MOP is fulfilled.
- Standard MOP: 5 years from key collection date
- SERS flats: Different MOP rules may apply — check with HDB
- Subsidised flats: Must fulfil MOP before selling on open market
- Non-citizen spouse: Additional conditions may apply for SPR/foreigner households

2. Determine Your Selling Price
Getting the price right is critical. Price too high and your flat sits unsold for months. Price too low and you leave money on the table. Here are three methods to determine a fair selling price:
Method 1: Recent Transaction Data
Check recent HDB resale transactions in your block or estate using the HDB Resale Price Checker tool. Look at sales from the past 6 months for the same flat type and similar floor level. This gives you a market-reality baseline.
Method 2: HDB's e-Valuation Report
Buyers' banks will order a valuation report to determine the flat's market value. While you can't order one yourself as a seller, understanding that your asking price needs to be defensible against the bank's valuation helps you avoid overpricing.
Method 3: Comparative Market Analysis (CMA)
This is what a good property agent does — analyse recent transactions, current listings, and market conditions to recommend a realistic price range. A CMA considers your specific floor, facing, condition, and remaining lease.
3. Prepare Your Flat for Sale
First impressions matter. Buyers often decide within the first 30 seconds of walking in. You don't need to renovate — but you do need to make your flat presentable.
- Declutter — remove excess furniture and personal items. Less is more.
- Deep clean — especially kitchen, bathrooms, and windows.
- Fix minor issues — leaky taps, chipped paint, broken handles. Small things that signal "well-maintained".
- Lighting — replace dim bulbs. Bright homes feel bigger and more welcoming.
- Photographs — invest in professional photography. Most buyers search online first.
4. Register Your Intent to Sell
You must register your Intent to Sell on the HDB Resale Portal before listing. This is free and valid for 12 months. You'll need your SingPass to log in.
Registration is mandatory — you cannot grant an Option to Purchase (OTP) without it. The portal guides you through step by step.
5. Should You Engage a Property Agent?
You can sell your HDB flat without an agent — HDB's process is designed to allow DIY transactions. However, most sellers engage an agent for good reason:
- Pricing accuracy — agents have access to transaction data and market knowledge that helps avoid under- or over-pricing
- Marketing reach — professional photos, portal listings, social media exposure
- Negotiation — handling offers, counteroffers, and buyer agents
- Paperwork — OTP preparation, HDB appointment coordination, and timeline management
- Time savings — managing viewings, fielding enquiries, and filtering serious buyers
Agent commission for HDB resale is typically 1-2% of the selling price. Make sure you understand what's included before signing the exclusive agreement.
6. The Option to Purchase (OTP)
When a buyer agrees to your price, you grant them an Option to Purchase. Here's how it works:
- Buyer pays you an option fee (typically $1,000 to $5,000)
- You grant the OTP — this gives the buyer 21 calendar days to decide
- If the buyer exercises the OTP, the sale proceeds. If they don't, you keep the option fee.
- Once exercised, both parties submit the resale application to HDB
7. Costs of Selling Your HDB
Selling isn't free. Here's what to budget for:
| Cost Item | Typical Amount | Notes |
|---|---|---|
| Agent commission | 1-2% of sale price | Negotiable — clarify inclusions |
| Conveyancing (legal) fees | $2,000 - $3,500 | Lawyer handles the legal transfer |
| HDB resale levy | Varies | Only if you bought subsidised flat before |
| Outstanding HDB loan | Full repayment | Settled from sale proceeds |
| CPF refund (with accrued interest) | Mandatory | Returns CPF used + accrued interest |
| Mortgage early repayment penalty | 0-1.5% | Check with bank if on bank loan |
The CPF refund is often the biggest surprise for sellers. All CPF used (including accrued interest at 2.5% p.a.) must be returned to your CPF OA. This reduces your cash proceeds.
8. The Timeline — How Long Does It Take?
From listing to completion, a typical HDB resale transaction takes 3-4 months:
| Stage | Duration |
|---|---|
| Marketing & viewings | 2-8 weeks (varies) |
| OTP negotiation & exercise | Up to 21 days |
| HDB resale application | ~8 weeks for approval |
| Completion & handover | Within agreed date |
9. Common Mistakes to Avoid
- Overpricing based on your renovation cost — buyers pay for location, size, and condition — not your IKEA kitchen
- Ignoring remaining lease — flats with shorter leases (below 60 years) face CPF and loan restrictions for buyers
- Not checking CPF refund impact — sellers are often shocked by how much goes back to CPF
- Rushing to sell before having a plan — if you're upgrading, know your next move before committing
- Skipping the Intent to Sell registration — you can't proceed without it
10. Ready to Sell? Here's What to Do Next
If you're thinking about selling your HDB flat, the first step is understanding your numbers — what your flat is actually worth, what you'll owe in CPF refunds, and what you'll walk away with in cash. I can help you work through all of this.
Frequently Asked Questions
How long does it take to sell an HDB resale flat?
Typically 3-4 months from listing to completion. The marketing phase varies (2-8 weeks), followed by the OTP exercise period (21 days), and HDB's approval process (~8 weeks).
Can I sell my HDB flat before MOP?
No. You must fulfil the 5-year Minimum Occupation Period (MOP) before selling on the open market. Early termination is only possible in exceptional circumstances (e.g., divorce, financial hardship) and requires HDB approval.
How much does it cost to sell an HDB flat?
Key costs include agent commission (1-2%), conveyancing fees ($2,000-$3,500), and CPF refund (all CPF used plus 2.5% accrued interest). Some sellers also face a resale levy if they previously bought a subsidised flat.
Do I need a property agent to sell my HDB flat?
No, you can sell without an agent through HDB's Resale Portal. However, most sellers engage an agent for pricing accuracy, marketing, negotiation, and paperwork management. Commission is typically 1-2% of the sale price.
What is the CPF refund when selling HDB?
When you sell your HDB flat, all CPF funds used for the purchase (including monthly loan repayments) plus accrued interest at 2.5% p.a. must be refunded to your CPF Ordinary Account. This is mandatory and reduces your cash proceeds.
Should I sell my HDB flat before or after buying a new property?
This depends on your financial situation and risk tolerance. Selling first gives certainty on your budget but means temporary housing. Buying first avoids the rush but requires bridging finance. Work through the numbers with a trusted agent before deciding.
