Residential Property Market Measures TDSR SSD LTV

Three sets of numbers quietly decide how much property you can actually buy in Singapore: the Total Debt Servicing Ratio, the Loan-to-Value limit, and, when you sell, the Seller’s Stamp Duty. Most buyers only meet these rules at the bank counter, which is the worst possible time to learn them. This guide does the opposite. It puts the real 2026 figures on the table, shows you the TDSR sum worked out line by line, and explains which of these limits is the one that will actually cap your loan.

We will start with the rule that surprises people most, because it is the one that decides your number before you have even chosen a flat.

TDSR: The 55% Rule, Worked Out

The Total Debt Servicing Ratio is a MAS rule capping your total monthly debt repayments at 55% of your gross monthly income. “Total” is the word that catches people. It is not just the new home loan. It is the home loan plus your car loan, credit card minimums, personal loans, everything, added together.

The formula itself is simple:

TDSR = (Total monthly debt obligations ÷ Gross monthly income) × 100%

Any tdsr calculator you find online is just running this one line. The part worth understanding is what the bank feeds into it, because two adjustments quietly shrink your number:

• The stress test. The bank does not calculate your mortgage at today’s rate. It uses a higher notional rate, around 4% in 2026, to check you could still cope if rates climbed. Your real instalment may be lower, but you are assessed on the stressed one.
• The variable income haircut. Bonuses, commission, rental and other non-fixed income are cut to 70% before they count. A S$30,000 annual bonus is worth S$2,500 a month on paper, but only S$1,750 of it counts towards your income for TDSR.

A worked example

Say your gross income is S$10,000 a month, all fixed salary, and you already pay S$1,000 a month on a car loan.

• Your TDSR ceiling: 55% × S$10,000 = S$5,500 a month for all debt.
• Subtract the existing car loan: S$5,500 − S$1,000 = S$4,500 left for the mortgage.
• At the roughly 4% stress rate over 25 years, S$4,500 a month supports a loan in the region of S$850,000.

Clear that car loan before you apply and the full S$5,500 is available for the mortgage instead, which can lift your borrowing limit by well over S$100,000. That single move is the highest-leverage thing most buyers can do, and it is why the advice is always to tidy your other debts first.

MSR vs TDSR: The Second Cap Only HDB Buyers Face

If you are buying an HDB flat or an executive condominium from a developer, a second ratio stacks on top of the TDSR: the Mortgage Servicing Ratio. The distinction between msr vs tdsr trips up a lot of upgraders, so here it is plainly.

For an HDB buyer you must satisfy both, and the MSR is usually the tighter of the two. A debt-free couple can sail through the 55% TDSR yet still be capped by the 30% MSR on the housing loan alone. For a private property purchase, MSR does not apply at all; only TDSR and LTV do.

LTV: The Cap Set by the Property, Not Your Income

Where TDSR limits you by income, the Loan-to-Value limit caps borrowing as a percentage of the property’s price or valuation, whichever is lower. The rest you fund from CPF and cash. The ladder steepens with each property you already have a loan on:

Two traps live in this table. First, stretch the loan tenure beyond 30 years or past age 65 and each LTV tier drops by a further 5 percentage points. Second, and this snares HDB upgraders constantly: if you are still on the title of your existing flat when you exercise the Option to Purchase on a new place, the bank treats the new loan as a second-property loan at 45%, not 75%. Selling first, timing a simultaneous completion, or decoupling are the usual ways around it.

Which Limit Actually Caps You?

This is the question that matters, because your real borrowing limit is simply the lower of the two. They bind different people:

• First-time buyer, strong income, no other debt. LTV usually binds. You could afford more than 75%, but the bank will not lend past it.
• Upgrader or investor, or anyone carrying a car loan. TDSR (or MSR for HDB) usually binds first, often well before you hit the LTV ceiling.

Knowing which camp you fall into tells you where to focus. If LTV binds, the lever is your downpayment savings. If TDSR binds, the lever is clearing debt or extending tenure. Pulling the wrong lever wastes effort on the limit that was never going to be the problem.

SSD: The One That Hits on the Way Out

The first two rules govern buying. Seller’s Stamp Duty governs selling, and only if you sell quickly. It is a tax on residential property sold within a holding period from purchase, designed purely to discourage speculative flipping. The rate is tiered and falls the longer you hold, reaching zero once the full holding period passes.

For genuine owner-occupiers this almost never bites, because they hold far longer than the window. The buyers who need to watch it are those purchasing a near-complete project or anyone whose plans might force an early sale. If there is any chance you will need to exit within the first few years, check the current holding period and tiers before you commit, because SSD lands as a lump sum exactly when you are trying to move on.

Putting the Three Together

Sequenced properly, the rules become a planning checklist rather than a series of nasty surprises:

• Before you shop, run the TDSR sum on your real income and debts, remembering the stress rate and the income haircut, so you know your ceiling.
• When you pick a property, check the LTV tier for your situation and confirm you have the cash portion of the downpayment, not just the CPF.
• If you might sell early, factor the SSD holding period in from the start.

None of these rules are obstacles in the way the word “cooling measures” suggests. They are fixed parameters, knowable in advance, and a buyer who runs the numbers early walks into the bank already knowing the answer rather than hoping for one.

Frequently Asked Questions

What is the TDSR limit in Singapore in 2026?

The Total Debt Servicing Ratio is capped at 55% of gross monthly income, a level in place since December 2021. It covers all monthly debt repayments combined, not just the home loan, and banks assess it using a stress-test interest rate of around 4% rather than your actual rate.

How do I calculate my TDSR?

Divide your total monthly debt obligations by your gross monthly income and multiply by 100%. Your new mortgage must keep that figure at or below 55%. Remember that variable income such as bonuses is cut to 70% before it counts, and the mortgage is stress-tested at a higher notional rate, so a tdsr calculator gives an estimate rather than a guarantee.

What is the difference between MSR and TDSR?

TDSR caps all your debts at 55% of income and applies to every property loan. MSR caps only the housing loan at 30% of income and applies solely to HDB flats and executive condominiums bought from developers. HDB buyers must satisfy both, and the 30% MSR is usually the tighter limit.

How much can I borrow under the LTV limit?

For a first housing loan the limit is 75% of the price or valuation, with a 25% downpayment of which at least 5% must be cash. A second loan drops to 45%, and a third or more to 35%. Long tenures or borrowing past age 65 reduce each tier by a further 5 percentage points.

Does Seller’s Stamp Duty affect ordinary owners?

Rarely. SSD only applies if you sell residential property within the holding period after buying, and the rate falls to zero once that period passes. Most owner-occupiers hold far longer and never trigger it; it mainly affects short-term sellers and those who may need to exit early.
