TDSR Private Property Singapore: What Buyers Must Know in 2026
Buying a private condo or landed property in Singapore? The Mortgage Servicing Ratio does not apply to you — but the TDSR 55% cap and the MAS 4% stress test absolutely do. Here is exactly how your maximum loan is calculated, and where borrowers most commonly fall short.
The Key Distinction: Private Property Has No MSR
Many buyers approaching their first private property purchase assume the same rules that govern HDB flat loans apply to condos and landed homes. The most important difference is this: the Mortgage Servicing Ratio (MSR) — the 30% income cap on your mortgage instalment — does not apply to private residential property.
MSR exists specifically for HDB flats and Executive Condominiums. For private property, only the Total Debt Servicing Ratio (TDSR) of 55% governs how much you can borrow. This distinction matters enormously in practice — it allows private property buyers to take a larger loan relative to their income than an HDB buyer could.
How TDSR Is Calculated for Private Property
The TDSR formula looks straightforward, but the MAS stress-test requirement introduces a critical nuance: banks cannot assess your repayment capacity at the actual loan rate. They must use the higher of the actual rate or 4% per annum as the assessment floor.
In practice, since most 2026 fixed rates sit between 1.4% and 1.9% p.a., the stress test rate of 4% is almost always the governing figure. This means your qualifying monthly instalment — for TDSR purposes — is calculated as if you are paying 4% interest, regardless of what your actual loan rate is. For a full breakdown of how the floor rate is set, see our guide: Understanding the MAS 4% Stress Test (2026).
Notice the gap: the bank qualifies you at an instalment of S$5,700/month, but your actual payment at 1.65% would be only S$4,220. The stress test is intentionally conservative — this buffer is by design.
What Reduces Your TDSR Headroom
Every existing debt obligation reduces the amount available for your mortgage instalment. For private property buyers — often higher-income professionals with multiple financial commitments — TDSR can bite in unexpected ways.
Each existing obligation — car loan, personal loan, credit cards — directly reduces the monthly instalment available for your private property mortgage. TDSR is calculated on gross income, before CPF contributions.
- Car loans & personal loans: Full monthly instalment counted against TDSR
- Credit cards: 5% of outstanding balance per month (MAS rule), regardless of whether you pay in full each month
- Existing investment property loans: Monthly instalment on all outstanding property loans included at full value
- Student loans & renovation loans: Monthly repayments counted in full
- Guarantor obligations: If you are a co-borrower or guarantor on another loan, partial inclusion may apply
Variable income rule: Bonuses, commissions, and rental income are discounted by 30% when computing your eligible gross income for TDSR. Only 70% of these income streams count toward your qualifying ceiling. For self-employed buyers, income is typically assessed on a 2-year average of NOA figures.
LTV Limits: How Much Can You Actually Borrow?
Even if your TDSR headroom supports a larger loan, the Loan-to-Value (LTV) limit sets an absolute ceiling on the loan quantum as a percentage of the property's purchase price or valuation, whichever is lower.
- First property (no outstanding home loans): Max LTV 75%. Down payment: 25%, of which at least 5% must be cash.
- Second property (one outstanding home loan): Max LTV 45%. Down payment: 55%, with a minimum 25% in cash.
- Third or subsequent property: Max LTV 35%. Down payment minimum 65%, minimum 25% in cash.
- Loan tenure > 30 years or extends past age 65: LTV reduced by 5 percentage points across all tiers.
For private property buyers upgrading from an HDB flat, the simultaneous ownership of both properties (during the transition period) triggers the second-property LTV of 45%. Timing the sale of the HDB flat concurrently with the private property purchase — or decoupling ownership to free one party's name — are strategies worth exploring before committing.
The 4% Stress Test: What It Means for Your Maximum Loan
The 4% stress rate increases your notional monthly instalment by roughly 60% compared to an actual 1.65% rate. On a S$2M property, this can translate to a difference of S$250,000–S$350,000 in qualifying loan quantum.
To illustrate the practical impact of the stress test, consider a buyer with S$15,000 gross monthly income and no existing debts purchasing a S$2,000,000 private condo:
Here, LTV is the binding constraint. But for buyers with existing debts or lower income, it is TDSR that limits the loan — meaning the actual loan approved could be significantly less than the LTV-permitted maximum.
Additional Buyer's Stamp Duty: The Other Number That Matters
TDSR governs your loan; Additional Buyer's Stamp Duty (ABSD) governs your cash outlay. For private property buyers, ABSD is a critical figure that must be funded in cash — it cannot be financed.
- Singapore Citizens, 1st property: 0% ABSD
- Singapore Citizens, 2nd property: 20% ABSD
- Singapore Citizens, 3rd & subsequent: 30% ABSD
- Singapore Permanent Residents, 1st property: 5% ABSD
- Singapore Permanent Residents, 2nd & subsequent: 30% ABSD
- Foreigners (all purchases): 60% ABSD
On a S$2M second property for a Singapore Citizen, ABSD alone is S$400,000 — a cash obligation on top of the 5% minimum cash down payment of S$100,000. Proper financial planning for a private property upgrade must account for this upfront.
Before You Make an Offer
The single most effective thing a private property buyer can do before putting down an Option Fee is to obtain an In-Principle Approval (IPA) from a bank. An IPA is free, non-binding, and valid for 30 days. It gives you a confirmed loan quantum based on your actual income documents, existing debts, and the property price — all stress-tested at the MAS 4% floor rate.

Working with a mortgage broker allows you to receive IPAs from multiple banks simultaneously — at no cost to you — and compare the quantum, rate, and conditions each lender offers. Banks pay the referral fee upon disbursement.
