Income needed
Under the 30% Mortgage Servicing Ratio for HDB flats, an instalment of S$3,062.27 needs a gross household income of at least S$10,207.56 a month. Under the 55% TDSR, it needs at least S$5,567.76 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
- HDB loans are capped at 25 years and must be fully repaid by age 65.
- A second housing loan drops the LTV limit sharply and raises the minimum cash downpayment to 25%.
- Banks test your TDSR at a stress-test rate, not the advertised rate, so your borrowing limit is lower than you might expect.
- 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.
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stamp duties and monthly instalments, but using CPF reduces the money compounding for retirement, and the amount withdrawn plus accrued interest must be refunded to your CPF account when you sell.
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.
