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.
