Income needed
Under the 30% Mortgage Servicing Ratio for HDB flats, an instalment of S$12,326.83 needs a gross household income of at least S$41,089.44 a month. Under the 55% TDSR, it needs at least S$22,412.42 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%.
- Using CPF for housing reduces what is left for retirement, and you must refund the amount used plus accrued interest when you sell.
- 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.
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stamp duties and monthly instalments, but using CPF reduces the money compounding for retirement, and the amount withdrawn plus accrued interest must be refunded to your CPF account when you sell.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.
