How these were worked out
Room for new loan = 55% × income − existing monthly debts.
Property is the largest purchase most Singaporeans make, and stamp duties, loan limits and cash requirements are front-loaded. Small mistakes in these figures can mean a shortfall at completion, so it pays to run the numbers before you commit to an option to purchase.
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stamp duties and monthly instalments, but using CPF reduces the money compounding for retirement, and the amount withdrawn plus accrued interest must be refunded to your CPF account when you sell.
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.
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.
Tips
- Banks test your TDSR at a stress-test rate, not the advertised rate, so your borrowing limit is lower than you might expect.
- Using CPF for housing reduces what is left for retirement, and you must refund the amount used plus accrued interest when you sell.
- Stamp duty must be paid within 14 days of signing, so have the cash ready before you exercise the option.
