TDSR and MSR Explained: How Much Can You Borrow for a Singapore Property in 2026?

Before you fall in love with a property in Singapore, you need to know how much you can borrow. The answer is determined by two MAS-mandated rules: the Total Debt Servicing Ratio (TDSR) and, for HDB and EC purchases, the Mortgage Servicing Ratio (MSR). This guide breaks both down with real numbers.

Why TDSR and MSR Exist

When property prices and borrowing were rising rapidly in the early 2010s, MAS introduced TDSR in June 2013 as a supply-side lending guardrail. The goal was to prevent buyers from over-leveraging. MSR was introduced alongside it, specifically to keep HDB flat purchasers within debt-servicing limits appropriate to their income levels.

Both rules apply regardless of the property type or lender — they are industry-wide requirements, not bank-by-bank policies.

Total Debt Servicing Ratio (TDSR)

The Rule

All monthly debt obligations combined cannot exceed 55% of your gross monthly income.

"All debt obligations" includes:

The proposed new mortgage
Car loan / hire-purchase
Credit card minimum payments (3% of outstanding balance per month)
Personal loan instalments
Student loan repayments
Any other regular debt service

The Stress Rate

MAS requires banks to stress-test your mortgage affordability using a floor rate of 4% per annum for TDSR purposes, even if the actual mortgage rate is lower. This ensures you can afford the loan even when rates rise.

For variable-rate loans, the stress rate is applied to the entire loan. For fixed-rate loans, some banks apply the actual rate during the fixed period and then switch to the 4% floor for the variable tail.

Income Haircuts

Not all income is counted at face value:

Income Type	Counted At
Fixed monthly salary	100%
13th month bonus	100% ÷ 12 per month (annualised)
Variable bonus / commission	70% (30% haircut)
Rental income	70%
Part-time / freelance income	Case by case; generally 70%

TDSR Worked Example

Profile: Married couple, combined gross income S$18,000/month (one partner earns S$11,000, one earns S$7,000).

Item	Monthly
Combined gross income	S$18,000
TDSR limit (55%)	S$9,900
Existing car loan	S$1,200
Credit card minimum payments	S$300
Available for new mortgage	S$8,400

Maximum loan at 4% stress rate, 30-year tenure:

A mortgage of S$8,400/month at 4% over 30 years supports a principal of approximately S$1,765,000.

With LTV at 75% (first loan), the maximum property value is:

Loan ÷ 0.75 = S$1,765,000 ÷ 0.75 = ~S$2,353,000

This couple can afford a property worth up to approximately S$2.35M (before other considerations).

Mortgage Servicing Ratio (MSR)

The Rule

For HDB flats and new Executive Condominiums, the monthly mortgage repayment cannot exceed 30% of gross monthly income.

MSR is more restrictive than TDSR. It applies only to:

HDB loans (from HDB)
Bank loans for HDB flat purchases
Bank loans for EC purchases from developer (during the initial sale)

MSR does NOT apply to resale EC purchases (after 10-year privatisation) — those are subject to TDSR only.

The Income Cap

Unlike TDSR, the MSR does not haircut variable income at a separate rate — the 30% cap applies to total gross monthly income. However, income documentation requirements apply similarly.

The Stress Rate for MSR

HDB concessionary loan: 0.1% above CPF OA rate (currently 2.5% + 0.1% = 2.6%)
Bank loan for HDB/EC: 4% floor rate (same as TDSR)

MSR Worked Example

Profile: Household income S$10,000/month, buying an HDB BTO flat.

Item	Monthly
Combined gross income	S$10,000
MSR limit (30%)	S$3,000

Maximum HDB loan at 2.6% (HDB rate), 25-year tenure:

Monthly repayment of S$3,000 at 2.6% over 25 years supports a loan of approximately S$632,000.

At 80% LTV (HDB concessionary loan):

Loan ÷ 0.80 = S$632,000 ÷ 0.80 = ~S$790,000 maximum flat price

For a bank loan at 4% stress rate, 30 years, S$3,000/month supports approximately S$630,000. At 75% LTV: maximum flat ~S$840,000.

Practical implication: MSR creates a very tight ceiling for HDB purchases. A household earning S$10,000/month cannot buy an HDB resale flat priced above ~S$790,000–S$840,000 through conventional financing. Some buyers who want pricier flats must bring more cash or CPF savings to reduce the required loan.

When TDSR and MSR Both Apply

For HDB and new EC purchases, both TDSR and MSR apply simultaneously. The binding constraint (whichever allows the lower loan) governs.

In most cases, MSR is more restrictive because:

MSR cap is 30% vs TDSR's 55%
MSR applies to the HDB/EC mortgage only, while TDSR stacks all debts against 55% of income

If a household has no other debts, the TDSR ceiling on an HDB mortgage would theoretically be 55% of income — but MSR restricts it to 30%. MSR therefore governs.

If a household has substantial other debts (car, credit cards), TDSR may become the binding constraint even below the 30% MSR ceiling.

LTV Limits: The Second Constraint

Even if TDSR/MSR allows a larger loan, Loan-to-Value (LTV) limits cap borrowing as a percentage of property value.

Loan	LTV Limit
First bank loan	75%
Second bank loan	45%
HDB concessionary loan	80%

LTV drops to 55% for bank loans if tenure exceeds 30 years or extends past age 65.

In practice, LTV is often the binding constraint for higher-value properties where income is sufficient to service the loan but the required equity is large.

How to Maximise Your Borrowing Capacity

Reduce existing debt before applying: Pay down car loans, clear credit card balances. Each S$1,000 reduction in monthly debt obligations frees up approximately S$200,000 in additional mortgage capacity at the 4% stress rate.
Include all documented income: Commission, bonuses, and rental income — properly documented — count toward TDSR income (at 70%).
Extend tenure to age 65: Longer tenure reduces monthly repayment, allowing a larger loan within the TDSR/MSR cap. Note: extending beyond 30 years triggers LTV reduction.
Co-borrow with a spouse or family member: Adding a co-borrower increases the income base and therefore the loan ceiling.
Get an IPA first: Many banks offer an In-Principle Approval (IPA) that tells you the maximum loan amount before you look at properties. This prevents falling in love with properties outside your range.

Common Misconceptions

"I earn enough to service the loan so the bank will lend me the money." The bank doesn't just look at whether you can service the proposed loan — it adds ALL your existing debts and stress-tests everything at 4%. Income is not the only factor.

"TDSR only applies to local properties." False. From September 2022, the TDSR framework applies to all property loans secured against any property, including overseas properties financed by Singapore banks.

"The 4% stress rate is the actual loan rate." No. The 4% is only for qualification purposes. If your actual loan rate is 3%, you pay 3% — but you must qualify as if it were 4%.
