Income needed
Under the 30% Mortgage Servicing Ratio for HDB flats, an instalment of S$1,474.43 needs a gross household income of at least S$4,914.75 a month. Under the 55% TDSR, it needs at least S$2,680.77 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 must be paid within 14 days of signing, so have the cash ready before you exercise the option.
- A second housing loan drops the LTV limit sharply and raises the minimum cash downpayment to 25%.
- Seller's Stamp Duty can wipe out the gains on a quick resale, so check your holding period before selling.
- Banks test your TDSR at a stress-test rate, not the advertised rate, so your borrowing limit is lower than you might expect.
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.
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.
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.
