How to Buy HDB in Singapore: Your Complete 2026 Step-by-Step Guide

Buying your first HDB flat is a five-stage process: HFE Letter, BTO or resale, loan choice, OTP, completion. This 2026 guide flags every mortgage, CPF, and grant decision along the way.

HDB Eligibility in 2026: Who Can Buy

Eligibility is the gate. Fail one criterion and the loan and grants do not matter. Rules below apply to first-time buyers in 2026.

Requirement Condition
Citizenship At least one Singapore Citizen in the application
Age At least 21 (35+ for singles under SSC Scheme)
Family nucleus Married couple, fiancé/fiancée, parent-child, orphaned siblings, or singles 35+
Income ceiling (BTO) S$14,000/month for couples and families (S$21,000 extended); no ceiling on resale
Property ownership Must not own private residential property locally or overseas at application
Cooling period 30-month wait if you sold a previous HDB; MOP rules apply
First-timer status Not previously bought from HDB or taken a CPF housing grant

Singles aged 35 and above can buy a 2-room Flexi BTO flat in non-mature estates or any resale flat. Two unmarried Singapore Citizens aged 35+ can apply jointly under the Joint Singles Scheme. Full details sit on the HDB Buying a Flat portal.

Affordability Checks Before You Shop

Three numbers decide what you can buy. Run them before any showflat or viewing.

TDSR
All debts capped at 55% of gross income, stress-tested at 4.0% p.a.
MSR
HDB mortgage instalment capped at 30% of gross monthly income.
CPF OA
Balance available for downpayment, stamp duty, and monthly servicing.

Run these checks with our TDSR/MSR affordability calculator. For background, read TDSR explained and the MAS 4% stress test. Framework set by MAS.

The 4% stress test applies to bank loans only; HDB loans use the headline 2.6% p.a. for affordability. The MSR 30% cap is HDB and EC specific.

The 5-Step HDB Buying Process

Five-stage HDB purchase journey from HFE Letter to key collection

The five stages from HFE Letter to keys. The mortgage decision sits at Step 3, but it shapes your eligibility from Step 1 onwards.

01

Apply for the HFE Letter Mortgage CPF

The HFE Letter is mandatory before you can ballot for a BTO or submit a resale application. It confirms your buyer status, eligible CPF grants, and maximum HDB concessionary loan. Processing takes 1 to 3 weeks; the letter is valid for 9 months. Start here, not at a showflat.

02

Choose Between BTO and Resale

BTO is subsidised and balloted; resale trades on the open market. Trade-offs:

Factor BTO Resale
Price Subsidised, below market Market rate
Wait time 3–5 years (ballot to keys) 8–14 weeks (OTP to keys)
Location Mostly non-mature estates Any estate, any block
Income ceiling S$14,000/month for couples; S$21,000 for extended families No ceiling on purchase
CPF grants EHG up to S$120,000 EHG + CHG + PHG up to S$230,000

BTO suits buyers who can wait and want maximum subsidy. Resale suits buyers who need to move soon, want a specific estate, or earn above the BTO ceiling.

03

Pick HDB Loan or Bank Loan Critical

This decision shapes your cashflow for 25 years. The HDB concessionary loan is 2.6% p.a. (CPF OA + 0.10%), 80% LTV, zero cash needed. Bank loans start from 1.40% p.a. fixed in 2026, cap LTV at 75%, and need a minimum 5% cash component. Full comparison in our HDB loan vs bank loan guide. For a bank loan, get an In-Principle Approval (IPA) from each shortlisted lender — free, non-binding, valid 30 days.

04

Exercise the Option to Purchase

For resale, pay an Option Fee up to S$1,000, then exercise within 21 calendar days by paying the Option Exercise Fee. Combined deposit at exercise is 5% to 10% of the price and forms part of your downpayment. For BTO, HDB invites you to a flat selection appointment after a successful ballot; you pay the booking fee on the spot. A conveyancing lawyer is required either way (budget S$2,500 to S$3,500).

05

Complete the Purchase and Collect Keys CPF

HDB schedules a completion appointment around 8 to 12 weeks after OTP exercise for resale. You sign the mortgage, execute the CPF charge, settle the balance downpayment plus stamp duty, and collect the keys. Bank loan disbursement happens on the same day; HDB loans disburse directly through HDB. The bank lock-in starts here, and your CPF OA begins funding monthly instalments.

CPF Housing Grants Worth Claiming

CPF housing grants are non-repayable and applied directly to your purchase or outstanding loan. First-time buyers often stack two or three; the HFE Letter confirms eligibility.

EHG — BTO & Resale
Up to S$120,000
Household income ≤ S$9,000/month. First-timer couples and families. Scaled by income band.
CPF Housing Grant — Resale
Up to S$80,000
Household income ≤ S$14,000/month. Stackable with EHG and PHG. Resale only.
PHG — Resale
Up to S$30,000
Living with parents: S$30,000. Within 4 km of parents: S$20,000. Resale only.

Maximum stacked: S$230,000 on resale (EHG + CHG + PHG) or S$120,000 on BTO (EHG only). Singles get half the family rate. Conditions on the HDB CPF Housing Grants page; see also using CPF OA for property.

Downpayment: HDB Loan vs Bank Loan

Side-by-side breakdown of down payment sources for HDB loan versus bank loan on an HDB flat

HDB loan: 20% downpayment, fully payable from CPF OA. Bank loan: 25% downpayment with minimum 5% cash. On a S$900,000 flat that is S$45,000 cash for a bank loan versus zero for an HDB loan.

On a S$900,000 resale flat, the downpayment maths breaks down like this:

Component HDB Loan Bank Loan
Loan-to-Value (LTV) Up to 80% Up to 75%
Downpayment required 20% of purchase price 25% of purchase price
Minimum cash S$0 — zero cash required 5% of purchase price
CPF OA component Up to 100% of downpayment Up to 20% of purchase price
On S$900,000 flat: cash S$0 S$45,000 minimum
On S$900,000 flat: CPF OA S$180,000 S$180,000
Interest rate (April 2026) 2.6% p.a. (CPF OA + 0.10%) From 1.40% p.a. fixed; typical 1.45%–1.65% — see current home loan rates
Stress test Headline 2.6% 4.0% MAS floor

Zero-cash downpayment is the HDB loan’s edge for buyers with thin savings. The bank loan’s edge is the rate gap: 1.45% versus 2.6% on a S$720,000 loan saves roughly S$8,300 in year-one interest. The catch is rate management — fixed and SORA packages reset after lock-in, so you must refinance when the lock-in expires. Buyers later needing liquidity can also tap an equity / cash-out loan.

“The mortgage is the line in the budget that compounds for 25 years. Get more than one bank’s number before you sign.”— Dan Ler, Mortgage Advisor at Nexus Mortgage SG

Common First-Timer Pitfalls

Skipping the HFE Letter. Buyers shop first, then learn their loan ceiling is lower than expected. Apply early so the HFE shapes your budget.

Underbudgeting the side costs. Plan for Buyer’s Stamp Duty, legal fees (S$2,500 to S$3,500), resale agent commission (around 1% + GST), valuation, fire insurance, and renovation. A S$50,000 to S$80,000 cash buffer on top of the downpayment is realistic for most resale buyers.

Taking the first bank quote. Rates on identical packages can differ by 30 to 50 basis points across lenders, with legal subsidies and cash rebates varying further. Compare quotes side by side before signing.

First-Time Buyer FAQ

Can singles buy an HDB flat in Singapore?

Singles aged 35+ can buy a 2-room Flexi BTO in non-mature estates (SSC Scheme) or any resale flat. Two unmarried Singapore Citizens aged 35+ can apply jointly under the Joint Singles Scheme. EHG for singles is half the family rate.

What is the HDB income ceiling for first-time buyers in 2026?

BTO: household income at or below S$14,000/month for couples and families (S$21,000 for extended families). Resale has no purchase ceiling, but EHG requires household income at or below S$9,000/month for the maximum grant.

How long does the HDB buying process take?

Resale: 8 to 14 weeks from OTP exercise to keys, plus 1 to 3 weeks for the HFE Letter. BTO: 3 to 5 years from successful ballot to keys, depending on construction stage.

Can I use CPF OA for the full HDB downpayment?

Yes — if you take an HDB concessionary loan. The 20% downpayment can be paid entirely from CPF OA with zero cash required. With a bank loan, the 25% downpayment needs a minimum 5% cash; the remaining 20% can come from CPF OA. On a S$900,000 flat: at least S$45,000 cash for a bank loan versus S$0 for an HDB loan. See using CPF OA for property.

What CPF housing grants are available in 2026?

EHG: up to S$120,000 for couples earning S$9,000/month or less (BTO and resale).

CPF Housing Grant: up to S$80,000 for resale buyers with income up to S$14,000/month.

PHG: up to S$30,000 for living with parents (S$20,000 if within 4 km). Resale only.

Maximum stacked on resale for a first-timer couple: S$230,000.

HDB loan or bank loan — which is better?

The HDB loan’s edges: zero cash downpayment, 80% LTV, and the option to switch to a bank loan later (the reverse is not allowed). Bank loans offer lower rates — from 1.40% p.a. fixed in 2026 versus 2.6% — but need 5% cash and active refinancing after the lock-in. Full breakdown: HDB loan vs bank loan. For a side-by-side downpayment and CPF cashflow comparison, see the Singapore Mortgage Free Report.

Do I need a mortgage broker to buy an HDB flat?

Not required, but an independent broker compares IPAs across 16+ lenders, weighs rate and rebate together, and stress-tests TDSR/MSR before you commit. Brokers are paid by the bank on disbursement — no cost to the borrower.
