How to Apply for a HDB Flat Under the Build-To-Order (BTO) Scheme

The Build-To-Order (BTO) scheme is HDB’s main avenue for selling new public housing. Flats are constructed only after enough buyers book them, cutting the risk of empty blocks. In 2026, HDB released around 16,200 BTO units across 12 projects, with an average application rate of 3.1 for first-timer families.

1. Eligibility Check

You must be at least 21 years old and a Singapore citizen. Your household must have at least one other Singapore citizen or permanent resident. Income ceiling is $14,000 for families and $7,000 for singles buying a 2-room Flexi flat. You cannot own other property locally or overseas, and you must not have taken more than two HDB housing loans previously. Check the HDB website’s eligibility letter service to get a pre‑assessment before a launch.

2. Choose a BTO Launch

HDB announces BTO exercises in February, May, August, and November. Each launch lists specific estates, unit types, and indicative prices. Recent 2026 launches in Tengah and Kallang/Whampoa offered 3‑room flats from $230,000 and 4‑room flats from $380,000. Study the site plans and priority schemes like the Married Child Priority Scheme (MCPS) that give extra ballot chances. Use HDB’s e‑brochure for detailed floor plans and the projected completion date, which in 2026 averages 3.2 years.

3. Submit Your Application

Apply online during the one‑week window, usually the last 7 days of the launch month. Pay a $10 application fee by credit card or PayNow. You can only submit one application per launch. On the form, indicate your preferred flat type and estate. HDB counts only the first submission if you apply multiple times. In a typical 2026 exercise, about 80% of applications come on the first and last day.

4. The Ballot Process

HDB runs a computerised ballot. Each valid application gets a random queue number. If your number falls within the supply of available flats (e.g., number 200 for 200 units), you are guaranteed a selection appointment. Otherwise, you are placed on a waiting list. Queue numbers are announced about 3 weeks after the application closes. Priority schemes increase your chances: the MCPS quota reserves 30% of flats, and the Parenthood Priority Scheme sets aside another 30%.

5. Flat Selection Appointment

If you get a queue number, HDB sends an invitation packet with an appointment date, typically 4–8 weeks after the ballot results. Attend the session at HDB Hub with your co‑applicants. Bring your NRIC, recent payslips, and CPF statements. At the counter, you pick an available unit and sign the Option to Purchase. Pay the option fee — $500, $1,000, or $2,000 depending on flat type — by NETS or cashier’s order. If you reject all offered units, your application is void and you lose your chance for that launch.

6. Signing the Lease and Payment

Within 9 weeks of the option date, you must exercise the option by signing the Agreement for Lease. At this stage, you pay the downpayment: 10% if you take an HDB loan, or 20% if using a bank loan. You can use CPF Ordinary Account savings for the downpayment. HDB finance officers will work out your loan eligibility and monthly instalments on the spot. In 2026, the average HDB loan rate remained at 2.6%, fixed for 5 years.

7. Waiting for Your Keys

Construction starts after the project reaches the required take‑up rate, usually 70% of units booked. HDB updates the progress quarterly via the My HDBPage portal. The typical waiting time for a 2026 BTO project is 2.5 to 3.5 years. Once built, HDB schedules a key collection appointment, where you pay the balance of the purchase price, stamp duties, and home protection insurance. You’ll go through a unit inspection with the building contractor before getting the keys.

FAQ

Q: Can I apply for a BTO flat with a friend? Only under the Joint Singles Scheme, where both are single, 35 or above, and meet the income ceiling. They are limited to 2‑room Flexi flats in non‑mature estates.

Q: What happens if I fail to book a flat twice? If you are a first‑timer and reject two chances to select a flat, your first‑timer priority status is downgraded to second‑timer for one year.

Q: Can I change my queue number? No. Queue numbers are computer‑generated and final. Asking HDB to re‑ballot is not possible.

Q: How do I know the exact completion date? HDB provides an indicative Probable Completion Date (PCD) at launch. It gets confirmed about 1 year before key collection, based on actual construction progress.
