ℹ️ MSR applies only to HDB flats and ECs financed by bank loans or HDB loans. The 30% cap is computed on qualifying income. TDSR (55%) also applies — whichever is more restrictive applies.
FAQ
What is MSR?
Mortgage Servicing Ratio (MSR) is a MAS regulation that limits your monthly HDB/EC loan repayment to 30% of your gross monthly income. It applies only to HDB flats and executive condominiums — not private property.
What is the difference between MSR and TDSR?
MSR (30%) only covers the specific HDB/EC loan. TDSR (55%) covers ALL debt obligations combined. Both limits apply when taking an HDB/EC loan — you must comply with both, so typically the more restrictive limit applies.
How is qualifying income calculated?
Fixed income (salary, CPF contributions) counts at 100%. Variable income (bonuses, overtime, commission) counts at 70%. Rental income counts at 70%. Investment income may count if it's consistent. Self-employed income uses the last 2-year average.
Can I increase my MSR limit?
No — the 30% MSR cap is fixed by MAS regulation. To borrow more: (1) increase income, (2) reduce other monthly debt obligations, (3) extend loan tenure (up to 30 years for bank loan), or (4) reduce loan amount via higher down payment.
