Background
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.
