Why Both MSR and TDSR Matter
When securing a home loan in Singapore, understanding the Mortgage Servicing Ratio (MSR) and Total Debt Servicing Ratio (TDSR) is essential. These two regulatory measures, set by the Monetary Authority of Singapore (MAS), work together to ensure responsible borrowing and long-term financial stability. While they overlap for certain property types, their distinct roles make them equally critical in shaping your loan eligibility.
MSR: Protecting Mortgage Affordability
The Mortgage Servicing Ratio (MSR) caps your monthly mortgage payment at 30% of your gross monthly income, but it only applies to HDB flats and Executive Condominiums (ECs) purchased directly from developers. Its primary purpose is to ensure that your mortgage remains affordable, preventing you from taking on a loan that could overwhelm your budget.
For example, with a monthly income of SGD 5,000, your mortgage payment cannot exceed SGD 1,500—keeping your housing costs manageable.
TDSR: Ensuring Overall Debt Sustainability
The Total Debt Servicing Ratio (TDSR) takes a wider view, limiting your total monthly debt obligations—including your mortgage, car loans, and other liabilities—to 55% of your gross monthly income. Applicable to all property loans in Singapore, TDSR ensures you can sustain all your financial commitments, not just your mortgage.
For instance, if your income is SGD 8,000 and you have SGD 1,000 in existing debts, your mortgage payment is capped at SGD 3,400 to stay within the TDSR limit of SGD 4,400.
Complementary Roles in Loan Eligibility
While MSR focuses solely on your mortgage for HDB or EC purchases, TDSR evaluates your entire debt portfolio. This dual framework matters because:
- Targeted Protection: MSR safeguards HDB and EC buyers from overextending on housing costs, a critical concern given their affordability focus.
- Holistic Oversight: TDSR prevents over-borrowing across all debts, ensuring you maintain financial flexibility regardless of property type.
- Combined Impact: For HDB or EC loans, both limits apply, and the stricter one governs. If your other debts push you beyond TDSR's 55% cap, your eligible loan amount shrinks—even if it meets MSR.
