Buying an HDB flat in Singapore as of 2026 follows four routes: BTO (3–5 year wait, lowest pricing), SBF (1–2 year wait, mixed locations), OBF (immediate, residual stock), and resale (immediate, market pricing). All routes require an HDB Flat Eligibility (HFE) letter, satisfy income ceilings (S$14k family / S$7k single), and operate under a 5-year Minimum Occupation Period for standard flats (10 years for Plus and Prime). Grants of up to S$160,000 are available for first-time buyers of resale flats.
The Singapore HDB framework
HDB flats house approximately 78% of Singapore's resident population. The HDB (Housing & Development Board) operates the world's largest public-housing programme, offering heavily subsidised flats to Singapore Citizens (and PRs as part of family households) under strict eligibility rules. Source: HDB.
All HDB flats are 99-year leasehold, with land reverting to the State at lease expiry. HDB classification was restructured in August 2024 into three tiers: Standard, Plus, and Prime — with progressively stricter resale conditions on higher tiers.
Four routes to buy an HDB flat
| Route | Wait | Selection | Pricing tier | Grants |
|---|---|---|---|---|
| BTO (Build-To-Order) | 3–5 years | Widest (new project) | Subsidised (lowest) | EHG only |
| SBF (Sale of Balance Flats) | 1–2 years | Limited (residual) | Same as BTO | EHG only |
| OBF (Open Booking) | Immediate keys | Very limited | Same as BTO | EHG only |
| Resale (open market) | 3 months | Wide (any approved listing) | Market price (+25–30% vs BTO) | EHG + Family Grant + Proximity (up to S$160k) |
BTO offers the lowest pricing but longest wait. Resale offers immediate occupation but pays market price plus full BSD on the purchase. See BTO vs SBF vs OBF detailed comparison.
The HFE Letter: prerequisite for everything
Before any HDB application, you need an HDB Flat Eligibility (HFE) letter. The HFE confirms your eligibility for: HDB loan, grant amounts, income ceiling status, and family scheme placement.
Apply via HDB Flat Portal using SingPass. Processing takes approximately 21 working days. The letter is valid for 6 months; reapply if it expires before you exercise an OTP.

2026 BTO and resale pricing benchmarks
| Flat type | BTO non-mature | BTO mature | Resale non-mature | Resale mature |
|---|---|---|---|---|
| 3-room | S$280–320k | S$330–380k | S$380–450k | S$450–550k |
| 4-room | S$330–400k | S$400–520k | S$450–580k | S$580–750k |
| 5-room | S$430–540k | S$520–700k | S$580–750k | S$750–950k |
| Executive flat | n/a (no new EC at HDB) | n/a | S$700–900k | S$900k–S$1.3M |
HDB Resale Price Index (RPI) reached 192.0 in Q1 2026 (+4.2% YoY). The "million-dollar HDB" segment has grown but remains under 5% of total resale volume. See HDB RPI detail.
5 vs 10 year MOP (Minimum Occupation Period)
Standard flats: 5-year MOP. Plus and Prime flats: 10-year MOP. MOP starts at key collection and ends at the 5-year (or 10-year) anniversary.
During MOP, the owner cannot: sell on open market, rent out the whole flat, or buy a private property. Room rental is allowed if the owner continues residing in the flat. See full MOP guide.
Financing: HDB Loan vs Bank Loan
First-time HDB buyers choose between:
- HDB Concessionary Loan: 80% LTV, 2.6% rate, 25-year tenure, full CPF financing (zero cash component required if CPF balance sufficient).
- Bank Loan: 75% LTV, 1.04–1.75% rates as of May 2026, 30-year tenure, 5% cash component required.
The bank loan saves S$300–S$500/month on a S$300,000 mortgage at current rates — but requires upfront cash. For buyers with substantial CPF balance and low cash savings, the HDB loan is simpler and grant-stackable.
