Income needed
Under the 30% Mortgage Servicing Ratio for HDB flats, an instalment of S$5,547.07 needs a gross household income of at least S$18,490.25 a month. Under the 55% TDSR, it needs at least S$10,085.59 with no other debts. Banks test affordability at a higher stress-test rate, so the real requirement is higher for bank loans.
Things to check
- Banks test your TDSR at a stress-test rate, not the advertised rate, so your borrowing limit is lower than you might expect.
- HDB loans are capped at 25 years and must be fully repaid by age 65.
- Budget for legal fees, valuation, renovation and moving costs on top of the downpayment and stamp duties.
- Stamp duty must be paid within 14 days of signing, so have the cash ready before you exercise the option.
Background
Most Singaporeans live in HDB flats, which can be financed with an HDB concessionary loan at 0.1% above the CPF Ordinary Account rate or with a bank loan. Private property must be financed with a bank loan, and banks offer fixed, floating and SORA-pegged packages.
Beyond the price, buyers should budget for legal fees, valuation, home insurance, renovation and furnishing. Running the figures in advance helps you decide how much cash to hold back and whether a smaller loan or longer tenure makes more sense.
CPF Ordinary Account savings can pay for the downpayment, stamp duties and monthly instalments, but using CPF reduces the money compounding for retirement, and the amount withdrawn plus accrued interest must be refunded to your CPF account when you sell.
