Income needed
Under the 30% Mortgage Servicing Ratio for HDB flats, an instalment of S$10,272.36 needs a gross household income of at least S$34,241.20 a month. Under the 55% TDSR, it needs at least S$18,677.02 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
- Stamp duty is based on the purchase price or market value, whichever is higher.
- Banks test your TDSR at a stress-test rate, not the advertised rate, so your borrowing limit is lower than you might expect.
- Using CPF for housing reduces what is left for retirement, and you must refund the amount used plus accrued interest when you sell.
- Budget for legal fees, valuation, renovation and moving costs on top of the downpayment and stamp duties.
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.
Singapore's property market is shaped by cooling measures introduced since 2009, including Additional Buyer's Stamp Duty, loan-to-value limits and debt servicing ratios. These rules are adjusted when the market runs hot, so the numbers you see today may differ from what friends paid a few years ago.
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.
