Frequently Asked Questions (FAQ)

How does the monthly instalment calculator help with my property investment planning?

Using the monthly instalment calculator allows you to stress-test your finances by estimating repayment amounts based on different interest rates. This helps you determine an affordable budget for your property purchase and understand the long-term impact on your cash flow.

What factors influence my maximum loan eligibility in Singapore?

Your maximum loan eligibility is primarily influenced by the Total Debt Servicing Ratio (TDSR) framework, your age, existing financial commitments, and the specific property type (HDB, EC, or private condo). These factors determine how much you can borrow while remaining within regulatory limits.

Why should I calculate my loan repayment period in relation to my retirement age?

Planning your loan tenure against your retirement age is crucial for asset progression. Extending your loan too far into retirement can impact your cash flow during your golden years; identifying the optimal repayment period helps ensure your property remains a sustainable investment throughout its holding period.
