Income needed
Under the 30% Mortgage Servicing Ratio for HDB flats, an instalment of S$4,314.39 needs a gross household income of at least S$14,381.31 a month. Under the 55% TDSR, it needs at least S$7,844.35 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
- Using CPF for housing reduces what is left for retirement, and you must refund the amount used plus accrued interest when you sell.
- Seller's Stamp Duty can wipe out the gains on a quick resale, so check your holding period before selling.
- 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%.
Background
Stamp duties are paid upfront. Buyer's Stamp Duty applies to every purchase at tiered rates up to 6%, while ABSD depends on the buyer's residency status and how many residential properties they already own. Sellers who dispose of a property within the holding period pay Seller's Stamp Duty.
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.
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.
