New HDB flats sold via balloted exercises, priced below resale market and taking ~3–4 years to complete. Subject to Minimum Occupation Period of 5 years after collection of keys.
Build-To-Order is HDB's flagship new-flat sales programme. HDB only starts building a project once enough applicants commit to buying. This 'build only when there's demand' approach replaced the earlier ready-to-occupy sales model in 2002.
BTO flats are sold below market value and are subject to ownership and resale restrictions designed to keep them on the public housing track.
Application: a balloting exercise opens roughly 4 times a year (Feb, May, Aug, Nov). You apply via HDB's website during a ~7-day window.
Ballot result: ~1 month later. Successful applicants get a queue number and pick a unit at the booking appointment.
Construction: ~3 to 5 years from application to key collection. Shorter (~2.5 years) for Shorter Waiting Time projects launched 2023.
Total timeline: budget for ~4 years between applying and moving in.
BTO prices are typically 20% – 40% below comparable resale flats in mature estates. The discount narrows in non-mature estates.
First-timer couples qualify for: Enhanced CPF Housing Grant (up to S$120,000, income-based), Family Grant (S$80,000 for ≤4-room), Proximity Housing Grant (S$30,000 if buying near parents).
All grants are applied to reduce the purchase price, with any unused portion going into CPF OA.
Minimum Occupation Period: 5 years from the date of key collection. During MOP you cannot sell or rent out the whole flat.
Income ceiling at point of application: S$14,000 for families buying a flat with subsidy, S$7,000 for singles buying a 2-room flexi.
Citizenship: at least one applicant must be Singaporean. Mixed-nationality households use the Non-Citizen Spouse Scheme.
Two-bites rule: you can only own two subsidised flats in your lifetime, and there's a resale levy on subsequent purchases.
Build-To-Order is HDB's flagship new-flat sales programme. HDB only starts building once enough applicants commit to buying, then sells the flats at subsidised prices (typically 20% – 40% below comparable resale).
Typically 3 – 5 years from ballot application to key collection, sometimes longer in mature estates. Some Shorter Waiting Time (SWT) projects target ~2.5 years but are rare.
S$14,000 monthly household income for most family-unit BTO flats (S$21,000 for extended families). Singles applying for 2-room flexi flats are capped at S$7,000.
Applicants submit applications during a balloting exercise (typically Feb, May, Aug, Nov). HDB then randomly assigns queue numbers, weighted by category (first-timers get priority over second-timers, family / parenthood priority schemes apply). Successful applicants pick units in queue order at booking appointments.
