How do you apply for an HDB BTO flat? In five steps: get an HFE letter, apply during a sales launch, wait for the ballot, book a flat, then sign the Agreement for Lease. Your HDB BTO application only goes through with a valid HFE letter in hand on the day you apply. HDB takes up to a month to issue one, so apply at least a month before the launch you're aiming for. Here's each step in order, with what you pay and when.
A BTO (Build-To-Order) flat is a new HDB flat you buy before it's built. HDB runs a few sales launches a year, and a computer ballot sets the queue. Applying on day one doesn't help: the June 2026 window ran for eight days, and when you apply within it doesn't change your odds.
Here's the order, start to finish:
Your flat's class, Standard, Plus or Prime, sets the rules you live with for the next 5 or 10 years, and the section on classes below covers them.
From 24 August 2026, the income ceiling for a BTO flat went up from S$14,000 to S$16,000 a month for families. For singles aged 35 and above, it went from S$7,000 to S$8,000, and both count for any HFE letter you apply for from that date onwards.
Extended or multi-generation families buying in a project with the S$16,000 ceiling can earn up to S$24,000. Some 3-room projects keep an S$8,000 ceiling, and the launch press release says which. Families buying a 99-year 2-room Flexi flat face an S$8,000 ceiling too. Income means everyone listed in your HFE letter application, added up.
One of you must be a Singapore Citizen, and the other a citizen or PR, both at least 21. A household of PRs only can't buy a new flat from HDB and is limited to resale.
A first-timer household with one citizen and one or more PRs pays a S$10,000 premium. You can apply for a S$10,000 Citizen Top-Up once a PR in the household becomes a citizen, or when you have a Singapore Citizen child.
Applying as fiances under the Fiance/Fiancee Scheme? You need to marry within 3 months of collecting your keys.
A first-timer single, a Singapore Citizen aged 35 and above who is unmarried, divorced or widowed, can buy a 2-room Flexi flat from HDB. The income ceiling is S$8,000.
You can't own any private home, in Singapore or overseas, when you apply for the HFE letter. If you sold one, the sale must have completed at least 30 months before your HFE application, counted from the legal completion date.
That 30-month wait applies to anyone buying a flat from HDB, not only to buyers taking an HDB loan. Own an HDB flat already? You'll need to sell it within 6 months of collecting your new keys.
The HDB Flat Eligibility (HFE) letter tells you upfront whether you can buy a new or resale flat. It also states your CPF housing grant and how big an HDB loan you can take. You must hold a valid one on the day you apply for a flat.
Apply on HDB's Flat Portal at least a month before the launch. HDB processes it within a month of getting all your documents, and it takes longer in the month of a launch. For November 2026, HDB asked buyers to send in every document by 25 September 2026.
The letter is valid for 9 months from the date it's issued. Our HFE letter guide lists the documents, and the HDB loan calculator gives you a feel for the monthly instalment.
HDB sets each project's class at launch, based on its location, and you can't change it. Plus and Prime flats come with extra subsidies, so they carry tighter rules.
The big one is subsidy recovery. When you sell a Plus or Prime flat, you pay HDB a share of the resale price or valuation, whichever is higher. HDB sets the rate per project, and in the February and June 2026 launches it was 6% or 8% for Plus and 10% to 14% for Prime.
| Rule | Standard | Plus | Prime |
|---|---|---|---|
| Minimum Occupation Period | 5 years | 10 years | 10 years |
| Subsidy recovery when you sell | None | Set per project (6% or 8% in 2026) | Set per project (10% to 14% in 2026) |
| Rent out the whole flat | After the MOP, with HDB approval | Never | Never |
| Rent out spare bedrooms | With HDB approval (3-room or bigger) | With HDB approval (3-room or bigger) | With HDB approval (3-room or bigger) |
| Resale buyer's income ceiling | None | Yes | Yes, as for a BTO |
| Buy private property | After the 5-year MOP | After the 10-year MOP | After the 10-year MOP |
The Minimum Occupation Period (MOP) is how long you must live in the flat. Until it ends, you can't sell, rent out the whole flat or buy private property. It starts from the legal completion of your purchase, which for a BTO is key collection. Any time you don't live there doesn't count.
Plus and Prime owners can never rent out the whole flat, even after the MOP, and their future buyers face an income ceiling too. Weigh it in our BTO vs resale comparison and the MOP explainer.
HDB ran three BTO launches in 2026. February offered 4,692 BTO flats in Bukit Merah, Sembawang, Tampines and Toa Payoh, plus 4,320 Sale of Balance flats. June offered 6,952 flats across 7 projects in Ang Mo Kio, Bishan, Bukit Merah, Sembawang and Woodlands.
The last one is November 2026, moved from October so buyers could get an HFE letter under the higher income ceilings. It has about 7,960 flats in Bedok, Geylang, Sembawang, Tengah, Toa Payoh and Yishun. Sembawang Anchor's 1,310 flats come with a waiting time of 2 years and 10 months.
HDB shares each project's class when the launch opens, and it updates every project's application rate several times a day. A project with a rate of about one or lower gives you better odds.
After the full Enhanced CPF Housing Grant of S$120,000, a 3-room Standard flat started from S$156,000 in February 2026. In June it started from S$145,000. A 4-room Standard flat started from S$224,000 in February and S$222,000 in June.
Those are HDB's starting prices for first-timer families who get the full grant, which only the lowest incomes do, so most buyers pay more. Your own price depends on the project, the floor and the unit, and HDB lists every unit's price on the Flat Portal during the launch. Our BTO price guide goes town by town.
Every application goes into a computer ballot, which sets the order you're invited to book. First-timer families get 2 ballot chances, and second-timer families get 1.
Families in the First-Timer (Parents & Married Couples) category get 3 chances. They also get first priority for 4-room or smaller flats in Standard projects. Missed out twice or more on Standard flats? You get one more chance for each new Standard application, up to 5 in total (4 for other first-timer families).
From the February 2027 launch, first-timer families with or expecting children get one more ballot chance for each Singapore Citizen child aged 18 and below.
Priority schemes give some groups a share of the flats:
You can apply under the Family and Parenthood Priority Scheme plus one other scheme. Turning down a booking slot when flats are left costs you, though. A first-timer family is then treated as a second-timer for a year, and any extra ballot chances drop back to 0. Second-timer families and first-timer singles can't apply at all for a year. HDB waives this if 10 or fewer BTO flats were left. Our guide to BTO ballot chances goes deeper.
When your number is called, you pick a unit at your booking appointment and pay the option fee. It's S$500 for a 2-room Flexi, S$1,000 for a 3-room and S$2,000 for a 4-room or bigger, and it counts towards your downpayment.
HDB then invites you to sign the Agreement for Lease within 9 months of booking. That's when the first part of the downpayment is due, with stamp duty and legal fees. With an HDB loan you can pay it all from your CPF Ordinary Account and grant if you have enough. A bank loan needs at least 5% of the price in cash.
Say you sign for a 4-room flat at S$345,000 with an HDB loan, and HDB acts for you. That's HDB's own example:
The Staggered Downpayment Scheme splits it further for eligible couples: with an HDB loan, 5% at signing and 20% at keys. You qualify as first-timers, or one first-timer and one second-timer, who booked an uncompleted flat of 5 rooms or smaller. You must also have applied for the HFE letter by the younger one's 30th birthday.
Couples on Deferred Income Assessment pay 2.5% at signing. That's for couples where one of you is still studying or in National Service, or finished within the past year. HDB tells you at booking if you qualify, and you don't need to apply.
| Stage | HDB loan or no loan | Bank loan | HDB loan, Staggered Downpayment Scheme |
|---|---|---|---|
| At lease signing | 10% of the price | 20% of the price, at least 5% in cash | 5% of the price |
| At key collection | 15% of the price | 5% of the price | 20% of the price |
An HDB loan covers up to 75% of the flat price, the same cap as a bank loan. That applies to flats from the October 2024 launch on. Its rate sits 0.1 percentage point above the CPF Ordinary Account rate. That's 2.5% from 1 October to 31 December 2026, so the HDB rate is 2.6%.
HDB sizes your loan at the higher of that rate and a 3.0% floor. So your eligible loan is a little smaller than a 2.6% sum suggests. With an HDB loan you may keep up to S$20,000 in your CPF Ordinary Account, and the rest goes into the flat.
Your monthly instalment can't exceed 30% of your gross monthly income, the Mortgage Servicing Ratio. A bank loan adds the Total Debt Servicing Ratio: all your debt repayments must stay at or below 55% of gross monthly income.
An HDB loan runs at most 25 years. It's shorter if 65 minus your average age, or the flat's remaining lease minus 20 years, gives fewer. A bank loan can run up to 30 years, but a lower loan limit may apply past 25. Test the instalment in the HDB loan calculator or the mortgage calculator, and compare both loans in HDB loan vs bank loan.
At key collection you pay the rest of the downpayment, plus a few small fees. With an HDB loan that's 15% of the price, or 20% under the Staggered Downpayment Scheme. Most of it can come from your CPF Ordinary Account.
| Item | How much |
|---|---|
| Rest of the downpayment | 15% of the price with an HDB loan, 5% with a bank loan |
| Survey fee | S$231.60 (3-room), S$299.75 (4-room), S$354.25 (5-room) |
| Registration fees, if HDB acts for you | S$38.30 for the lease, S$38.30 for the HDB mortgage |
| Stamp duty on the Deed of Assignment | 0.4% of the loan, up to S$500 |
| HDB fire insurance, 5 years | S$3.27 (3-room) to S$6.68 (Executive) |
| Home Protection Scheme | Yearly premium, from CPF or cash |
HDB fire insurance is compulsory while you have an HDB loan, and you renew it every 5 years. It covers the flat's internal structure, fixtures and what HDB built, not your renovation, furniture or belongings.
The Home Protection Scheme pays off the housing loan if the insured owner dies, becomes terminally ill or is permanently incapacitated. You must take it if you pay your monthly instalments with CPF.
Second-timers also pay a resale levy before key collection, in cash only.
First-timer families can get the Enhanced CPF Housing Grant of up to S$120,000. To qualify, the household's average gross monthly income over the 12 months before the HFE application must be S$9,000 or less. You also need to have worked for at least 12 months in a row and still be working when you apply. A first-timer and second-timer couple can get up to S$60,000.
First-timer singles can get up to S$60,000, with an income ceiling of S$4,500 when buying alone. The grant is highest at the lowest incomes and steps down to zero at the ceiling.
The grant goes into your CPF Ordinary Account and can pay your downpayment. The Proximity Housing Grant is for resale flats only. Some second-timer families can get the Step-Up CPF Housing Grant instead. Our HDB housing grants guide has the full table.
The money is spread across the wait rather than due at once. Here's the order with an HDB loan:
| Stage | When | What you pay |
|---|---|---|
| Application | During the launch window | S$10 fee |
| Booking | When your queue number is called | Option fee: S$500, S$1,000 or S$2,000 by flat type |
| Agreement for Lease | Within 9 months of booking | 10% downpayment (5% under the Staggered Downpayment Scheme), stamp duty and legal fees, less the option fee |
| Construction | Until the flat is built | Nothing |
| Key collection | When the flat is ready | The other 15% (or 20%), fees and fire insurance; monthly instalments start |
Each of these can cost you a launch or a flat, and most only show up after the ballot.
We'd start with the HFE letter, because nothing moves without it and it lasts 9 months.
Then we'd price the class: a Plus or Prime flat trades a 10-year MOP and a subsidy recovery for its location.
Last, we'd count the cash at lease signing. A bank loan needs at least 5% of the price in cash, while an HDB loan can run on CPF.
The one fact that settles most of this is your household income. It sets your grant, your loan and the flats you can apply for.
Yes. You must hold a valid HDB Flat Eligibility (HFE) letter on the day you submit your BTO application. Apply on HDB's Flat Portal at least a month ahead. HDB takes up to a month once it has all your documents, and longer in a launch month. The letter is valid for 9 months.
S$16,000 a month for families and S$8,000 for singles aged 35 and above, for HFE letters applied for from 24 August 2026. Before that it was S$14,000 and S$7,000. Extended or multi-generation families can earn up to S$24,000 in projects with the S$16,000 ceiling, and some 3-room projects keep an S$8,000 ceiling.
Standard flats have a 5-year MOP and no subsidy recovery, and you can rent out the whole flat after the MOP with HDB's approval. Plus and Prime flats have a 10-year MOP and can never be rented out whole. When you sell, you pay HDB a share of the price: 6% or 8% for Plus and 10% to 14% for Prime in the February and June 2026 launches.
With an HDB loan, you pay 10% of the price when you sign the Agreement for Lease and 15% at key collection. You can pay both from your CPF Ordinary Account. With a bank loan, 20% at signing, at least 5% of the price in cash, and 5% at keys. Eligible couples under the Staggered Downpayment Scheme pay 5% at signing with an HDB loan.
The Enhanced CPF Housing Grant. First-timer families with an average household income of S$9,000 or less get up to S$120,000, if they've worked for 12 months in a row. First-timer singles buying alone with S$4,500 or less get up to S$60,000. The Proximity Housing Grant is for resale flats only.
It depends on the project. HDB's shorter-waiting-time projects take under three years: Sembawang Anchor in the November 2026 launch quotes 2 years and 10 months. Sale of Balance flats are already built or further along, so their wait is shorter.
Not the whole flat during the MOP, and never the whole flat if it's Plus or Prime. A Standard flat can be rented out whole after its 5-year MOP with HDB's approval. In a 3-room or bigger flat, you can rent out spare bedrooms with HDB's approval.
Not on their own. You must be a Singapore Citizen applying with at least one other citizen or PR. A household of PRs only is limited to resale flats. A first-timer household of one citizen and one or more PRs pays a S$10,000 premium. It comes back as a Citizen Top-Up once a PR becomes a citizen.
No. You can't own any private home, in Singapore or overseas, when you apply for the HFE letter. Any you sold must have completed at least 30 months before that application. The wait applies to every buyer of a flat from HDB, whether or not you take an HDB loan.
You lose only the S$10 fee, and your first-timer status stays. First-timer families who miss out twice or more on Standard flats get an extra ballot chance next time. Turning down a booking slot when flats are left is different: a first-timer family is treated as a second-timer for a year.
Up to 75% of the price. The rate is 0.1 percentage point above the CPF Ordinary Account rate, so 2.6% for October to December 2026. HDB sizes your loan at a 3.0% floor. Your instalment can't exceed 30% of gross monthly income, and the loan runs at most 25 years. Your HFE letter states the exact amount.
