Income needed
Under the 30% Mortgage Servicing Ratio for HDB flats, an instalment of S$680.50 needs a gross household income of at least S$2,268.35 a month. Under the 55% TDSR, it needs at least S$1,237.28 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.
- Seller's Stamp Duty can wipe out the gains on a quick resale, so check your holding period before selling.
- Stamp duty is based on the purchase price or market value, whichever is higher.
- Budget for legal fees, valuation, renovation and moving costs on top of the downpayment and stamp duties.
Background
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.
The Total Debt Servicing Ratio limits monthly debt repayments to 55% of gross monthly income for any property loan, and the Mortgage Servicing Ratio limits the housing instalment to 30% of income for HDB flats and new executive condominiums. Banks apply a medium-term interest rate in these tests rather than the rate you will actually pay.
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.
