Applying for a BTO flat in 2026 starts before any flat goes on sale: you need a valid HDB Flat Eligibility (HFE) letter in hand on the day you submit your application. The other big change is the flat classification. Since the October 2024 sales launch, every new HDB project is sold as Standard, Plus or Prime, and the class decides your Minimum Occupation Period, whether you can ever rent out the whole flat, and how much you pay back to HDB when you sell. This guide walks the full journey in order: checking eligibility, getting the HFE letter, reading the classes, balloting, booking, the payment timeline, grants, and the MOP.
A BTO (Build-To-Order) flat is a new HDB flat built after enough buyers apply for a project. HDB runs sales exercises a few times a year, you ballot for the project you want, and a computer draws queue numbers. There is no first-come-first-served advantage, so applying on day one does not help your odds.
The 2026 sequence is: confirm you meet the eligibility rules, apply for an HFE letter and wait about a month for it, submit your flat application during a sales exercise while the HFE letter is still valid, get a ballot queue number, attend a booking appointment if your number is called, pay the option fee, sign the Agreement for Lease and pay the first part of the downpayment, then collect your keys two to four years later and pay the rest.
Throughout, the flat's class (Standard, Plus or Prime) sets the rules you live with for the next decade. Standard flats keep the familiar 5-year MOP. Plus and Prime flats carry a 10-year MOP, a permanent ban on renting out the whole flat, and a subsidy clawback when you sell.
Before anything else, work out which schemes you qualify under. Most buyers apply as a couple under the Public Scheme, but the rules differ by household type, and they decide both your flat options and your grants.
The income ceilings for new flats in 2026 are unchanged: a household monthly income of $14,000 or less for families buying up to a 5-room flat, $7,000 or less for singles buying a 2-room Flexi, and $21,000 or less for extended or multi-generation families. Income is assessed on your average gross monthly household income over the 12 months before your application.
If you are getting married, you apply under the Fiance/Fiancee Scheme and must register the marriage before collecting keys. For a new BTO flat, at least one applicant must be a Singapore Citizen; a household made up only of Singapore Permanent Residents cannot buy a new flat and is limited to the resale market. To count as a first-timer household and get the most grants, none of the applicants should have taken a housing subsidy or owned property before. Check the citizenship and household rules on HDB's eligibility page before you apply.
A single Singapore Citizen who is unmarried, divorced or widowed can buy a 2-room Flexi flat from HDB from age 35 (or from 21 if widowed or an orphan). Since the October 2024 launch, singles can apply for 2-room Flexi flats islandwide rather than only in non-mature estates, and up to 30% of the non-senior 2-room Flexi supply in each project is set aside for first-timer singles. The income ceiling for singles is $7,000.
Two ownership rules catch out applicants who assume they are clear. First, you cannot own any other property, local or overseas, when you apply, and if you previously owned private property you must have disposed of it before you apply. If you intend to take an HDB housing loan, the last private property must have been sold at least 30 months before your HFE application, measured from the legal completion date of the sale. Apply too soon after selling and HDB will turn down the loan.
Second, if you already own an HDB flat or another property and still want the new flat, you have to dispose of the existing one within 6 months of collecting the keys to your BTO. A household can also buy a new or subsidised flat from HDB at most twice; a third subsidised purchase is not allowed. Sort these out before you spend a month waiting on the HFE letter.
The HDB Flat Eligibility (HFE) letter replaced the old HDB Loan Eligibility letter and the various eligibility checks. You must hold a valid HFE letter on the day you submit your BTO application. Without it, your application will not go through.
Apply for the HFE letter through the HDB Flat Portal. It tells you upfront whether you can buy a new or resale flat, how much in CPF housing grants you qualify for, and how large an HDB housing loan you can take. HDB takes about a month to process it after you submit the full set of documents, and the queue is longer in the weeks around a sales exercise.
The HFE letter is valid for 9 months from issue. Plan backwards from the sales exercise you want. For the June 2026 exercise, HDB asked applicants to submit their HFE documents by 15 May 2026 to have the letter ready in time. Our HDB loan calculator gives you a feel for the monthly repayment before the letter confirms your loan amount.
The class is the single biggest decision in 2026. It is fixed by HDB based on the project's location, and you cannot change it. The flat is the same quality across classes; what differs is the subsidy, the restrictions, and how much of the gain you keep when you sell.
Plus and Prime flats sit in choicer or central locations and come with extra subsidies, so HDB attaches tighter conditions to keep them affordable and owner-occupied. The subsidy recovery is a percentage of the resale or valuation price (whichever is higher) that you return to HDB when you sell, after serving the 10-year MOP. Recent exercises have set it around 6 to 8 percent for Plus projects and about 9 percent for Prime, and the exact figure is stated in each project's launch documents.
| Feature | Standard | Plus | Prime |
|---|---|---|---|
| Minimum Occupation Period | 5 years | 10 years | 10 years |
| Subsidy recovery on resale | None | Yes (around 6-8%) | Yes (around 9%) |
| Rent out whole flat after MOP | Allowed | Never allowed | Never allowed |
| Rent out spare bedrooms | Allowed after MOP | Allowed after MOP | Allowed after MOP |
| Resale buyer: citizenship | Open to eligible buyers | At least 1 Singapore Citizen | At least 1 Singapore Citizen |
| Resale buyer: income ceiling | None | $14,000 family / $7,000 single | $14,000 family / $7,000 single |
| Buy private property after MOP | Allowed once MOP met | Only after full 10-year MOP | Only after full 10-year MOP |
A Plus or Prime flat can be in a location you could never afford on the open market, which is the draw. The trade-off is real: you are locked in for 10 years, you can never rent out the whole unit, your pool of future buyers is smaller because they must meet an income ceiling, and HDB takes a slice of the sale price. Run the numbers against a Standard flat or a resale unit before you decide. Our BTO vs resale comparison and MOP explainer cover the trade-offs in detail.
HDB launched 6,952 flats across 7 projects in the June 2026 exercise, in Ang Mo Kio, Bishan, Bukit Merah, Sembawang and Woodlands, with a mix of Standard, Plus and Prime units. Applications closed on 24 June 2026 at 11.59pm. HDB plans to launch about 19,600 BTO flats across the whole of 2026, so missing one exercise is not the end of the road.
Each sales exercise follows the same shape. HDB publishes the projects, prices and flat supply, you have roughly a week to apply online, and a computer ballot then assigns queue numbers. Your chance of getting a flat depends on your queue number relative to the number of units and the priority schemes ahead of you.
Submit one application per sales exercise through the HDB Flat Portal. The application fee is $10. After the exercise closes, the ballot draws your queue number, and HDB invites buyers in queue order to book a flat until the units run out.
Several priority schemes give you a better ballot position, and you should check which apply to you before choosing a project:
HDB usually publishes ballot results within about two months of the application window closing, and you get your queue number by email and post. The queue number is the whole game. HDB invites buyers in queue order to pick a unit, so a number larger than the supply for your flat type and town means you are unlikely to be called before the units run out. You can track how many people applied while the window is open: HDB refreshes the application count several times a day, which lets you switch to a less-balloted project before you commit.
Not getting a flat costs you nothing beyond the $10 fee, and it does not count against your first-timer status. You simply apply again at the next exercise. Our guide to BTO ballot chances breaks down how the priority schemes and first-timer weight change your odds.
If your queue number is called, you book a flat at an appointment and choose your unit from what is left. You pay an option fee on the spot, which later counts toward your downpayment. The option fee is based on flat type: $500 for a 2-room Flexi, $1,000 for a 3-room, and $2,000 for a 4-room or larger flat.
Within about four months you sign the Agreement for Lease and pay the first part of your downpayment. The downpayment size depends on your loan. With an HDB housing loan, the loan covers up to 75% of the price, so the downpayment is 25%, and you can pay all of it from your CPF Ordinary Account if you have enough, leaving zero cash outlay. With a bank loan, the 75% loan-to-value limit also applies, but at least 5% of the price must be in cash and the rest can come from CPF.
Eligible first-timer couples can use the Staggered Downpayment Scheme, which lowers the amount due at lease signing to 2.5% of the price, with the balance due when you collect keys. Weigh the loan choice carefully, since the HDB rate moves with CPF while a bank rate can be fixed or floating. The HDB loan vs bank loan comparison and our stamp duty calculator help you size the upfront cash.
The HFE letter gives you the exact loan figure, but the rules behind it are worth knowing before you fall for a flat you cannot finance. The HDB concessionary loan rate is 2.6% a year for the January to March 2026 period, pegged at 0.1 percentage point above the CPF Ordinary Account rate, so it shifts only when the OA rate does. Since the 20 August 2024 cooling measures, an HDB loan covers at most 75% of the price, the same loan-to-value cap as a bank loan, which is why the downpayment is 25%.
Your repayment is capped two ways. The Mortgage Servicing Ratio limits your monthly housing instalment to 30% of gross monthly income for any HDB flat. A bank loan adds the Total Debt Servicing Ratio on top, holding all your debt repayments to 60% of gross monthly income. The maximum HDB loan tenure is 25 years if you want the full 75% loan; stretching beyond that pulls the LTV down. The HDB loan calculator and mortgage calculator let you test the instalment against these caps before the letter lands.
The downpayment is not the last bill. At key collection you settle the remaining downpayment plus a cluster of smaller costs that surprise first-time buyers. Buyer's Stamp Duty is charged on the higher of price or valuation; for a typical 4-room BTO it runs to a few thousand dollars and can be paid from CPF. Conveyancing fees if HDB acts as your solicitor are modest and scale with the flat price, and there is a small survey fee.
Two insurance items kick in here. HDB Fire Insurance is compulsory while you have an outstanding HDB loan; it covers HDB's building structure and fittings, not your renovation or contents, is bought from the appointed insurer Etiqa for a five-year term, and must be paid in cash. The Home Protection Scheme is a mortgage-reducing insurance that clears the outstanding loan if the insured owner dies, is terminally ill, or is permanently disabled; it is required if you use CPF to pay the monthly instalment, the premium is deducted yearly from your Ordinary Account, and cover runs to age 65 or until the loan is repaid.
| Item | Roughly how much | Can you use CPF? |
|---|---|---|
| Buyer's Stamp Duty | On higher of price or valuation; a few thousand dollars for a 4-room | Yes, from CPF OA |
| Conveyancing / legal fees (HDB as solicitor) | Low hundreds, scales with flat price | Yes, from CPF OA |
| Survey fee | Small fixed fee by flat type | Yes, from CPF OA |
| HDB Fire Insurance (Etiqa, 5-year term) | Low, renewed every 5 years while loan is outstanding | No, cash only |
| Home Protection Scheme premium | Based on age, loan and cover; required if paying instalments by CPF | Yes, deducted yearly from CPF OA |
Grants are paid into your CPF Ordinary Account and reduce the cash and CPF you draw down, not your loan. For new BTO flats, the main grant is the Enhanced CPF Housing Grant (EHG), and the amount scales down as your income rises.
First-timer families can get up to $120,000 in EHG with a household income ceiling of $9,000. First-timer singles buying a 2-room Flexi alone can get up to $60,000 with an income ceiling of $4,500. The grant is highest at the lowest incomes and tapers in steps to zero at the ceiling. Use the HDB loan calculator to see how the grant changes your repayment, and read our HDB housing grants guide for the full breakdown.
Note that the Proximity Housing Grant and the Family Grant apply to resale flats, not new BTO flats, so a BTO buyer's grant is the EHG. If your eligibility is borderline, the figure in your HFE letter is the one that counts.
From application to keys, a BTO typically takes three to five years, most of it construction time. The cash and CPF you need is spread across the journey rather than due at once.
| Stage | When | What you pay |
|---|---|---|
| Application | Sales exercise week | $10 application fee |
| Booking appointment | Weeks after ballot | Option fee: $500 / $1,000 / $2,000 by flat type |
| Sign Agreement for Lease | Around 4 months after booking | Downpayment (25% with HDB loan, or 2.5% under Staggered scheme), less the option fee |
| During construction | 2-4 years | Nothing further until completion |
| Key collection | On completion | Remaining downpayment, stamp duty, legal fees, then monthly loan repayment begins |
The MOP is the period you must physically live in the flat before you can sell it or buy private property. It starts from the date you collect your keys and excludes any stretch where you do not occupy the flat, such as renting it out in full where that is allowed. For Standard flats the MOP is 5 years; for Plus and Prime flats it is 10 years.
During the MOP you cannot sell the flat, rent out the whole unit (renting spare bedrooms is allowed once you live there), or buy local or overseas private residential property. Breaking the conditions can mean HDB compulsorily acquires the flat. After the MOP, Standard owners can sell on the open market, rent the whole flat, and buy private property. Plus and Prime owners can sell after the 10 years but still cannot ever rent out the whole flat, and they pay the subsidy recovery on sale.
Most failed applications are not bad luck. They are avoidable slips in timing or eligibility that surface only after the ballot, when it is too late to fix.
Yes. You must hold a valid HDB Flat Eligibility (HFE) letter on the day you submit your BTO application. Apply for it through the HDB Flat Portal at least about a month ahead, since processing takes roughly a month and longer around a sales exercise. The letter is valid for 9 months.
The household monthly income ceiling is $14,000 for families buying up to a 5-room flat, $7,000 for singles buying a 2-room Flexi, and $21,000 for extended or multi-generation families. Income is averaged over the 12 months before you apply.
Standard flats have a 5-year MOP, no subsidy clawback, and you can rent out the whole flat after the MOP. Plus and Prime flats sit in better locations with more subsidies, carry a 10-year MOP, can never have the whole flat rented out, and require you to pay back a percentage of the sale price to HDB when you sell.
With an HDB loan, the downpayment is 25% of the price and can be paid entirely from your CPF Ordinary Account, so cash outlay can be zero. With a bank loan, at least 5% must be in cash. Eligible first-timer couples can pay just 2.5% at lease signing under the Staggered Downpayment Scheme and the rest at key collection.
The main grant for a new BTO is the Enhanced CPF Housing Grant: up to $120,000 for first-timer families (income ceiling $9,000) and up to $60,000 for first-timer singles (income ceiling $4,500). The Proximity Housing Grant and Family Grant apply to resale flats, not BTOs.
From application to key collection is usually three to five years, with most of that being construction time after you book. You can move in faster by applying for a Sale of Balance Flat or shorter-wait project, which are flats already built or further along.
Not during the MOP, and not the whole flat at all if it is a Plus or Prime flat. Standard owners can rent out the entire flat only after serving the 5-year MOP. Renting out spare bedrooms is allowed once you live in the flat, subject to HDB's occupancy rules.
Not on their own. To buy a new BTO flat, at least one applicant must be a Singapore Citizen. A household made up only of Permanent Residents cannot buy a new flat and is limited to the resale market. A PR can be the co-applicant alongside a Singapore Citizen.
Not at the point of application. You cannot own any other property, local or overseas, when you apply, and any private property you previously held must already be sold. If you plan to take an HDB loan, the last private property must have been disposed of at least 30 months before your HFE application, based on the legal completion date. If you still own a property when you collect the BTO keys, you must sell it within 6 months.
Nothing beyond losing the $10 fee. Your first-timer status is untouched and you can apply again at the next sales exercise. With about 19,600 BTO flats planned across 2026, a missed exercise is not the end of the road. Applying early in the window does not help, since the ballot is random.
An HDB loan covers up to 75% of the price, so you fund the remaining 25%. The concessionary rate is 2.6% a year for the January to March 2026 period. Your monthly instalment is capped at 30% of gross monthly income under the Mortgage Servicing Ratio, and the maximum tenure for the full loan is 25 years. The exact amount is set out in your HFE letter.
