Buying a Resale HDB Flat, Step by Step: The Process, the Money, the Grants and the Lease Check to Do First
From the option to the keys in about four months. Every step in order, what you pay and when, the grants, and why 38% of the flats resold last year would limit a 30-year-old's CPF and loan.
To buy a resale HDB flat you first get an HDB Flat Eligibility (HFE) letter, find a flat, and get an Option to Purchase from the seller (option fee up to $1,000). By the next working day you submit a Request for Value ($120); after the value is out, you exercise the option within 21 days (option fees totalling up to $5,000), and you and the seller submit the resale application ($80 each for a 3-room or bigger flat). HDB accepts it within 28 working days and completes about 8 weeks after that. With an HDB loan you pay 25% of the lower of price or value upfront, in cash or CPF. Grants for first-timers can reach $80,000, $120,000 and $30,000 from three schemes.
Buying a resale HDB flat is faster than waiting for a BTO flat and gives you far more choice, but the process runs on HDB's timetable and a handful of rules that catch first-time buyers out: the HFE letter you need before anything else, the 21-day option, HDB's valuation, and a lease test that quietly cuts what you can borrow.
This guide takes you through the steps in order, the money you need, the grants you can claim, what changes if you have owned a flat before, and how to check a flat before you commit. For the option itself, every payment and the exact timetable, see our guide to the HDB Option to Purchase. Rules are HDB's and CPF's, as at 25 September 2026.
How do you buy a resale HDB flat, step by step?
Start with an HFE letter and a check of the flat's lease against your age. Then take an Option to Purchase, ask HDB for the flat's value by the next working day, exercise the option within 21 days and submit the resale application with the seller; HDB accepts it within 28 working days and completes about 8 weeks later.
HDB runs every resale through its HDB Flat Portal, in this order (as of 2026, verify on HDB):
| Step | What you do | Time and cost |
|---|---|---|
| 1. HFE letter | Apply for an HDB Flat Eligibility letter: it confirms you can buy, your grants and your HDB loan. Ask banks for an In-Principle Approval at the same time if you want a bank loan | Free; up to about a month once HDB has your documents |
| 2. Find a flat | Choose a flat that fits your budget, your grants and the lease test (below); the seller must have registered an Intent to Sell for more than 7 days | Your own time |
| 3. Option to Purchase | Agree the price and take the OTP from the seller: a legally binding option on HDB's form | Option fee $1 to $1,000, in cash |
| 4. Request for Value | Ask HDB for the flat's value, which sets how much CPF and loan you can use. Not needed if you pay only in cash | By the next working day; $120; result typically within 10 working days |
| 5. Exercise the OTP | Once the value is out (and your bank's Letter of Offer, for a bank loan), sign and return the OTP | Within 21 calendar days of the option; option fees total at most $5,000 |
| 6. Resale application | You and the seller submit your portions, with documents | Within 7 days of each other; $40 each for a 1- or 2-room flat, $80 for 3-room and bigger |
| 7. Acceptance and approval | HDB checks both sides; you endorse the documents (including a health declaration for CPF's Home Protection Scheme if you use CPF or an HDB loan), pay the fees and the initial payment | Acceptance within 28 working days; documents about 3 weeks later |
| 8. Completion | Attend the appointment, pay the balance and collect the keys | About 8 weeks after HDB's acceptance, the earliest possible date |
Add it up and a resale takes about four months from the option if every step runs to HDB's stated limits. You can handle the purchase yourself or pay a property agency to help. The Option to Purchase guide sets out every payment on that timetable, and the HFE letter guide covers step 1.
Count from the HFE letter, not from the viewing: without a valid letter no seller can grant you an option.
How much money do you need to buy a resale HDB flat?
With an HDB loan, 25% of the lower of the price or HDB's value, from cash and/or CPF, plus stamp duty and fees; the option fees (up to $5,000) must be cash. With a bank loan at 75% you pay the same 25%, but at least 5% in cash. Any amount you agree above the value is not covered by the loan.
Four pieces of money, in the order you need them:
- Option fees, in cash. Up to $1,000 when the seller grants the option and the rest when you exercise it, capped at $5,000 in all. CPF says option fees cannot be paid from CPF. They count towards the price.
- The initial payment. With an HDB loan (up to 75% of the lower of price or value), you pay 25% of the lower of the two, from cash and/or your CPF Ordinary Account, including any grants. With a bank loan at 75%, it is also 25%, but at least 5% must be cash; at a 55% bank loan it is 45%, with at least 10% in cash.
- Stamp duty and fees. Buyer's stamp duty on the higher of price or value, stamp duty on the loan, HDB's legal fees and the Singapore Land Authority's registration fees; PR households buying their first resale flat also pay Additional Buyer's Stamp Duty at completion.
- Your CPF goes in first with an HDB loan. Each buyer may keep up to $20,000 in their CPF Ordinary Account; the rest "must be used to pay for the flat purchase ... before the HDB housing loan can be granted".
- The balance at completion, from the loan.
The value matters more than the price: HDB's value is "the basis for your CPF usage" and for the loan, so a price agreed above it has to be paid in cash. Our Option to Purchase guide works every payment and fee through for a median 4-room flat; PR buyers should also read can PRs buy a resale HDB flat. Run your own numbers in the Property Financial Planner.
Why should you check a resale flat's remaining lease against your age?
Because CPF, the HDB loan and the Enhanced CPF Housing Grant are all cut back when the lease will not last the youngest buyer (for the grant, the youngest core member) to age 95. On HDB's resale records, only 62% of flats resold from 2025-09 to 2026-08 had enough lease for a 30-year-old; 85% did for a 40-year-old.
Three rules run the same age-95 test on slightly different people: the youngest buyer using CPF (CPF), the youngest applicant (HDB loan) and the youngest core member, who can be an occupier such as a child (EHG).
- CPF: if it lasts the youngest buyer using CPF to 95, you can use your Ordinary Account savings up to the lower of price or value. If not, CPF use is capped at "a percentage" of that, and once you reach it you cannot use more "regardless of whether you have set aside your Basic Retirement Sum" (CPF).
- HDB loan: if the lease does not cover the youngest applicant to 95, "the LTV limit will be pro-rated from 75%" (HDB). The loan also runs no longer than the remaining lease minus 20 years, which bites on older flats.
- Enhanced CPF Housing Grant: the full amount needs a lease covering the youngest core member to 95; "Otherwise, the EHG amount will be pro-rated" (HDB).
How many resale flats pass, by the youngest buyer's age, on PropKaki's analysis of HDB's resale records:
| Youngest buyer's age | Remaining lease needed | Resales that pass | Share of all resales |
|---|---|---|---|
| 25 | 70 years or more | 13,265 | 54% |
| 30 | 65 years or more | 15,354 | 62% |
| 35 | 60 years or more | 17,472 | 71% |
| 40 | 55 years or more | 20,955 | 85% |
| 45 | 50 years or more | 22,932 | 93% |
PropKaki analysis of 24,592 HDB resales registered 2025-09 to 2026-08; remaining lease is HDB's figure at the time of sale. A flat that fails can still be bought, with pro-rated CPF, loan and grant. The shares describe the flats, not the people who bought them: an older buyer passes on a shorter lease.
It depends heavily on the flat type:
| Flat type | Resales | Median lease left | Pass for a 30-year-old | Pass for a 35-year-old |
|---|---|---|---|---|
| 2 Room | 750 | 91 years | 81% | 81% |
| 3 Room | 5,790 | 57 years | 28% | 35% |
| 4 Room | 10,817 | 75 years | 71% | 80% |
| 5 Room | 5,752 | 74 years | 78% | 85% |
| Executive | 1,470 | 67 years | 67% | 85% |
Three-room flats are the trap: they are mostly older, with a median 57 years left, so only 28% pass for a 30-year-old. A couple in their early thirties shopping for their first 3-room flat is looking at a market where most flats cut their CPF and loan. Check any flat's lease on HDB Map before you view it, and use CPF's housing usage calculator for the exact figure.
The lease you buy is measured against the youngest buyer, not the flat's age: check it before you fall for the flat.
Which grants can you get for a resale HDB flat?
First-timer families can combine three: the CPF Housing Grant (up to $80,000 for a 2- to 4-room flat, $50,000 for 5-room or bigger), the Enhanced CPF Housing Grant ($120,000 at household incomes of $1,500 or less, tapering to $5,000 at $8,501 to $9,000) and the Proximity Housing Grant ($30,000 to live with parents or a child, $20,000 within 4km). Income for the CPF Housing Grant must be up to $16,000.
HDB's resale grants for families, as of 2026 (verify on HDB):
| Grant | Amount | Key conditions |
|---|---|---|
| CPF Housing Grant (Family Grant) | 2- to 4-room: $80,000 (two citizens) or $70,000 (citizen and PR). 5-room or bigger: $50,000 or $40,000. A first-timer with a second-timer spouse: $40,000 (2- to 4-room) or $25,000 (5-room or bigger) | At least one first-timer core member; household income up to $16,000 ($24,000 for extended families); lease more than 20 years |
| Enhanced CPF Housing Grant (EHG) | For first-timer families, $120,000 at household incomes of $1,500 or less, falling by income band to $30,000 at $6,501 to $7,000 and $5,000 at $8,501 to $9,000; up to $60,000 for a first-timer and second-timer couple | Must first qualify for the Family Grant; household income up to $9,000; worked continuously for at least 12 months up to 2 months before the HFE letter application, and working when you apply; full amount only if the lease covers the youngest core member to 95 |
| Proximity Housing Grant (PHG) | $30,000 to live with parents or a child; $20,000 to live within 4km | Can be combined with the grants above |
Together that is up to $230,000 for a first-timer family earning no more than $1,500 a month (the only EHG tier that pays $120,000) buying a 2- to 4-room flat to live with their parents (PropKaki's sum of HDB's maximums; $220,000 if they live within 4km instead). Most families qualify for less. The Family Grant and EHG also require that no one owns private residential property or has sold one in the 30 months before the HFE letter application. The grant goes into your CPF Ordinary Account and reduces the price or the loan. Singles have their own grants, set out in our CPF housing grant guide.
There is no income ceiling for buying a resale Standard or unclassified flat without a grant: the $16,000 applies only if you claim the CPF Housing Grant, take an HDB loan, or buy a resale Plus or Prime flat.
Do you pay resale levy when you buy a resale HDB flat?
No. Resale levy is charged only when you buy a second subsidised flat, such as a new flat from HDB or an EC from a developer. HDB says that if you are buying a resale flat or private property, you need not pay it.
HDB's words: "If you do not intend to buy a second subsidised flat from HDB, i.e., you are buying a resale flat or private residential property, you need not pay the resale levy."
The levy exists to reduce the subsidy on a second subsidised flat. It applies when a second-timer buys a new flat from HDB or a new EC from a developer, and is a fixed amount based on the first subsidised flat sold (for a first flat sold on or after 3 March 2006; for a family, $15,000 for a 2-room up to $50,000 for an Executive flat, and $55,000 for an EC).
One thing to know when you buy resale with the CPF Housing Grant: HDB counts "A resale flat with CPF Housing Grant" as taking a housing subsidy. So buying resale with that grant today makes you a second-timer, with a levy to pay, if you later buy a new flat from HDB. Our resale levy guide covers the rest.
Can you buy another resale HDB flat after owning one?
Yes. Once you have lived in your current flat for its minimum occupation period (5 years for a Standard flat, 10 for Plus and Prime), you can apply for a new HFE letter, sell it and buy another resale flat, and HDB's Enhanced Contra Facility lets you use the sale proceeds for the purchase at the same time. No resale levy applies.
What changes the second time round:
- The MOP comes first. Everyone listed in a Standard or unclassified flat must live in it for 5 years (10 for Plus and Prime) before applying for an HFE letter, selling on the open market, renting out the whole flat or buying private property. The MOP counts from the legal completion of your purchase.
- Buy and sell together. HDB's Enhanced Contra Facility lets you use the cash proceeds and CPF refunded from the sale of your current flat to buy the next resale flat. Your sale must complete first, which can be on the same day, and the proceeds cannot pay stamp duty or legal fees. HDB approves it case by case and can refuse it where either flat carries a bank mortgage or a CPF charge, or private solicitors act.
- Or sell after. If you buy first, you must dispose of your existing flat within 6 months of the resale completion.
- Grants shrink. The Family Grant and EHG need at least one first-timer in the household. A second-timer couple gets neither, though the Proximity Housing Grant is open to any household that has not had it before; a first-timer married to a second-timer gets the smaller couple amounts.
- No resale levy on a resale purchase, even the second time.
Can you buy a resale flat while waiting for your BTO flat?
Only by cancelling the BTO booking, which costs you. After booking and before the Agreement for Lease you forfeit the option fee and cannot buy a resale flat with grants for a year; after the Agreement for Lease you forfeit 5% of the purchase price. Cancelling also cancels your HFE letter.
HDB's cancellation rules for a booked new flat:
- After booking, before the Agreement for Lease: you forfeit the option fee, and wait a year before applying for, or being an essential occupier of, a new flat, a resale flat with CPF housing grants, an EC from a developer and several other subsidised homes.
- After the Agreement for Lease, before the keys: you forfeit 5% of the purchase price. Legal fees are not refunded.
- Either way: the application cannot be reinstated, and the HFE letter you used is cancelled, so you apply for a fresh one before buying resale.
Cancel after booking but before the Agreement for Lease, and for a year after cancelling any resale flat you buy comes without CPF housing grants. Our guide to HDB public rental and interim housing sets out the full table and where to live while you wait for a BTO instead.
Is buying a resale HDB flat worth it compared with waiting for a BTO?
It is a trade of money for time and choice. HDB's own October 2025 comparison priced new 4-room flats at Fernvale Plains at $344,000 to $472,000 against $583,800 to $630,888 for nearby resale flats, but those new flats were about 32 months away; a resale completes in months, and 24,592 flats changed hands in the past year.
PropKaki does not tell you which to buy; the trade-offs are measurable:
| Resale flat | BTO flat | |
|---|---|---|
| Price | Market price, set by you and the seller | Priced by HDB below comparable resale flats (Fernvale Plains 4-room, Oct 2025: $344,000 to $472,000 new against $583,800 to $630,888 resale nearby) |
| Time to the keys | About four months from the option, if every step runs to HDB's limits | 31 to 48 months' estimated wait for the Standard projects in October 2025 |
| Choice | 24,592 resales in 26 towns over 2025-09 to 2026-08 | The projects in each launch, by ballot |
| Lease | What is left: a median 71 years on the flats resold | A fresh 99-year lease |
| Grants | Family Grant, EHG and PHG | EHG, plus the market discount HDB builds into the price |
| Resale levy for second-timers | None | Payable |
Prices and waiting times: HDB, Annex A of the October 2025 BTO exercise; HDB warns that resale comparables differ in attributes. Resale figures: PropKaki analysis of HDB resale records.
If you need a home within the year, or want a particular town and block, resale is usually the only way. If you can wait three to four years and live somewhere cheaply meanwhile, a BTO flat costs less. Map both in the property timeline planner.
A BTO discount is paid for in years; a resale premium buys them back.
What should you check before you sign the Option to Purchase?
Your HFE letter is valid, the flat's lease passes the age-95 test for your youngest buyer, the block has room under the ethnic and PR quotas, you can fund any price above the value in cash, and you know who pays any upgrading bill.
- ✓Your HFE letter is valid, and the people in it are the ones who will buy; any change means a fresh letter.
- ✓The flat's remaining lease covers your youngest buyer (and, for the EHG, your youngest core member) to 95, or you have worked out the pro-rated CPF, loan and grant.
- ✓The block and neighbourhood still have room for your household under the Ethnic Integration Policy and SPR quotas (our [EIP and SPR quota guide](/singapore-property-research/hdb-eip-spr-quota-check)).
- ✓The seller has registered an Intent to Sell for more than 7 days.
- ✓You have cash for the option fees (up to $5,000) and for any gap between the price and HDB's value.
- ✓For a bank loan, your Letter of Offer will be in hand before the 21-day option ends.
- ✓Whether the block is due an upgrading bill: the owner on the billing date pays, so a bill issued after completion is yours.
- ✓If the flat is a Plus or Prime flat: a 10-year MOP and no renting out the whole flat, ever.
- ✓Your completion date works with your move: HDB cannot bring it forward, and the seller may stay up to 3 months after completion only if you agree.
What happens at completion, and what can't you do afterwards?
At the completion appointment you sign the mortgage (for an HDB loan), take the keys, pay the seller the apportioned property tax and arrange your service and conservancy charges. From then, you must live in the flat for its minimum occupation period before selling, renting it out whole or buying private property.
At completion (about 8 weeks after HDB accepts the application):
- Inspect the flat with the seller beforehand, so vacant possession can be delivered on the day.
- You pay the balance of the price not covered by CPF or the loan, by cashier's order, or by NETS for payments under $9,999.
- With an HDB loan you must show HDB fire insurance from its appointed insurer, and sign the mortgage.
- You acknowledge the keys, pay the seller the apportioned property tax, and say how you will pay the first month's service and conservancy charges.
After completion:
- MOP: 5 years for a Standard or unclassified flat, 10 for Plus and Prime, counted from legal completion and only while you live there. Until then you cannot sell on the open market, rent out the whole flat, apply for another HFE letter or buy private property.
- Your old home: any HDB flat you own must be disposed of within 6 months of completion; if you rent from HDB, the rental flat goes back within 4 months.
- Bedrooms: in a 3-room or bigger flat you may rent out spare bedrooms with HDB's approval, even during the MOP (except in a 3Gen flat); see our guide to renting out an HDB flat or room.
What is the biggest mistake people make when buying a resale HDB flat?
Falling for a flat before checking its lease against the youngest buyer's age. If the lease won't last that buyer to 95, CPF, the HDB loan and the EHG are all pro-rated, and if you only run the numbers after taking the option, the option fee is already at stake.
It is easy to view a flat, fall for it and only then run the numbers. On an older flat that order is expensive: the lease test cuts your CPF, your loan and your grant at once, and the lease is on HDB Map before any viewing, so there is no reason to find out after the option fee is at stake. With 38% of recent resale flats failing the test for a 30-year-old, and most 3-room flats failing it, this is not a corner case.
