Six checks before taking on a monthly mortgage

A current framework for cash flow, interest rates, loan structure, CPF, debt ratios and resilience.

Six mortgage-commitment checks

  1. Purchase cash flow: downpayment, duties, fees and renovation before monthly repayments begin.
  2. Interest-rate risk: test the loan at materially higher rates, not only the initial package.
  3. Loan structure: tenure, age limits, fixed or floating periods and refinancing conditions.
  4. CPF usage: current housing limits, accrued interest and the impact on retirement balances.
  5. Debt ratios: current TDSR or MSR treatment and all other commitments.
  6. Resilience: income interruption, vacancy, maintenance and emergency liquidity.

The maximum approved loan is not necessarily a comfortable commitment. Use conservative assumptions and retain a household buffer.
