Notes, assumptions and sources (rules as at 24 September 2026)
- Loan tenure set to 25 years: the longest HDB allows (up to 25 years, ending by age 65 on the buyers' average age, and within the remaining lease less 20 years).
- Grants are subject to HDB's full eligibility conditions (citizenship, 12 months' continuous employment for EHG, ownership history, remaining lease to age 95). Your HFE letter confirms the exact amounts.
- CPF can be used for the downpayment (beyond the minimum cash), BSD, legal fees and monthly instalments, subject to CPF's Valuation Limit, Withdrawal Limit and remaining-lease rules. ABSD, option fees and any cash over valuation must be paid in cash.
- With an HDB loan you may keep up to $20,000 in your CPF Ordinary Account; the rest is used for the purchase.

Common questions
How long does it take to buy an HDB resale flat?
After the Option to Purchase you submit a Request for Value by the next working day and have up to 21 days to exercise. HDB accepts a complete resale application within 28 working days, documents are endorsed about 3 weeks later, and completion is about 8 weeks from acceptance. Allow roughly 3 to 4 months in all.
How much can I borrow with an HDB loan?
Up to 75% of the price or value, whichever is lower, over at most 25 years and not beyond age 65. Instalments must fit within the 30% Mortgage Servicing Ratio, assessed at a 3% floor rate. Household income must be $16,000 or less. The HDB rate is 0.1% above the CPF Ordinary Account rate.
Which grants can I get for an HDB resale flat?
First-timer families may get the CPF Housing Grant (Family) of up to $80,000, the Enhanced CPF Housing Grant of up to $120,000 depending on income, and the Proximity Housing Grant of $20,000 or $30,000 for living near or with parents or children. HDB's HFE letter confirms the amounts.
