How Much Property Can You Afford in Singapore? The 3/3/5 Rule (2026)

How much property you can afford is not the same as how much a bank will lend you. The bank’s limits tell you the most you can borrow. The 3/3/5 rule tells you what you can carry through a job loss, a rate rise or a price fall. In 2026, with most home loans priced at about 1.5–2.2%, the gap between the two is wider than it has been for years.

At a glance

• The 3/3/5 rule: have at least 30% of the price in cash and CPF, keep the mortgage at or below one-third of monthly income, and pay no more than five times your annual household income.
• The legal limits are looser. Banks may let all your debt payments reach 55% of income (TDSR). For HDB flats and new ECs, the mortgage alone is capped at 30% (MSR). Both are tested at a 4% rate for bank loans.
• Rule 1 is usually the one that binds. The downpayment and stamp duty alone cost about 27–28% of the price.
• Test your payment at 4%, not at today’s rate. Three-month SORA, the benchmark for floating loans, was about 3.7–3.8% in late 2023.

The 3/3/5 rule in one minute

Property Soul set out the rule in her 2014 book, and it caused heated debate on Propwise at the time. Each part guards against a different risk.

1. 30% of the price in capital. This covers the downpayment, Buyer’s Stamp Duty, legal fees and some renovation. If you cannot raise 30%, you have no buffer.
2. Mortgage at or below one-third of monthly income. This leaves room for living costs, savings and a rate rise.
3. Price at or below five times annual household income. This stops you from buying a home that only works if everything goes right for 25 years.

It is deliberately conservative. As one reader pointed out in 2014, a developer or agent would prefer a “1-2-10” rule. The point is not that you must pass all three tests. It is that you should know which ones you fail, and by how much.

What the rules allow you to borrow in 2026

Before you apply the 3/3/5 test, know the hard limits. These are set by MAS and HDB, and they changed several times after this article first appeared.

Limit	Applies to	2026 setting
Total Debt Servicing Ratio (TDSR)	All property loans from banks	All monthly debt payments ≤ 55% of gross income
Mortgage Servicing Ratio (MSR)	HDB flats; new ECs within MOP	Home loan payment ≤ 30% of gross income
Stress-test rate	Bank loans / HDB loans	4% / 3%
Loan-to-value (first loan)	Bank loan / HDB loan	75% (at least 5% in cash) / 75%
Maximum tenure	HDB loan / bank loan for HDB / private	25 / 30 / 35 years

If you read older guides, note what has changed. TDSR was 60% until December 2021. The stress-test rate was 3.5% until September 2022. The HDB loan limit was 90% until December 2021 and has been 75% since 20 August 2024.

Banks size your loan at the stress rate, not at your actual rate. That is why the legal limit already includes some protection. It does not include protection against losing a job, having a child or a long vacancy. That is what the 3/3/5 rule is for.

Worked example: one couple, four answers

Say a couple earns S$12,000 a month in gross income between them (S$144,000 a year). That is close to the 2025 median of S$12,027 a month for resident employed households, including employer CPF. They have S$200,000 in cash and CPF Ordinary Account savings, and no other debts. How much home can they afford?

Test	Calculation	Maximum price
3/3/5 Rule 1: 30% capital	S$200,000 ÷ 30%	about S$667,000
3/3/5 Rule 2: payment ≤ S$4,000	Loan at 4% over 30 years: S$837,800; at 75% LTV	about S$1.12m
3/3/5 Rule 3: 5 × income	5 × S$144,000	S$720,000
MSR (HDB flat, HDB loan)	S$3,600 a month at 3% over 25 years: loan of about S$759,000	Loan limit, not price
TDSR (private, bank loan)	S$6,600 a month at 4% over 30 years: loan of about S$1.38m	about S$1.84m, if they had S$460,000 for the 25% downpayment

The bank’s TDSR test would allow a loan of up to S$1.38m. At a floating rate of about 1.8%, that loan costs about S$4,970 a month, or 41% of their income. If rates go back to 4%, it costs S$6,600 a month, which is 55%. That is legal, but it is not comfortable.

The 3/3/5 rule gives a budget of about S$667,000, set by their capital. Check it. On a S$667,000 home, a 25% downpayment is S$166,700 and BSD is S$14,600. That is S$181,300, or 27% of the price, before legal fees and renovation. Their S$200,000 just covers it. A 75% loan of S$500,000 at 4% over 25 years costs about S$2,640 a month. That is 22% of income, well inside the one-third line.

So the couple can afford a home of up to about S$667,000 now. They can go higher later as their savings grow. That budget covers a typical 4-room HDB resale flat: on HDB’s resale transaction data, the median 4-room flat sold for about S$630,000 in Q2 2026 (Propwise calculation from registered resales, not an official HDB median). A new Standard 4-room flat costs much less. In HDB’s February 2026 BTO exercise, 4-room flats at Sembawang Voyage cost S$304,000 to S$422,000 before grants. A private condo is out of reach for now under the rule.

Is five times income realistic in 2026?

When Propwise first discussed the rule in 2014, a reader argued that five times income was “ridiculous”: a couple on S$10,000 a month could easily carry a S$1.5m condo. Run that case on 2026 numbers:

• A 75% loan of S$1.125m over 30 years costs about S$4,050 a month at 1.8%, which is 40% of S$10,000.
• At 4% it costs S$5,370, which is 54%. That just passes TDSR, if they have no other debts.
• The downpayment and BSD come to about S$420,000 (28% of the price).

So yes, it can be done, and some buyers do it. But a 54% payment ratio leaves almost nothing for a rate rise or a lost income. The old answer still holds. A higher multiple is a choice to accept more risk, not proof that the rule is wrong.

The gap is real. Five times the 2025 median household income from work is about S$722,000. That is above the median 4-room resale price (about S$630,000), but below the median 5-room flat (about S$738,000). New private homes are far beyond it. Suburban launches in 2026 sold at averages such as S$2,350 per sq ft at Lentor Gardens Residences. At that price a 1,000 sq ft unit costs about S$2.35m, or more than 16 times the median income.

A fair 2026 reading is this:

• For HDB buyers, 5x is often achievable, especially with grants. First-timer families buying resale can receive up to S$230,000 in grants.
• For private buyers, the multiple matters less than Rules 1 and 2. If you have 30% in capital and the payment at 4% stays under one-third of income, a 6x or 7x purchase can still be safe. If you fail both, the price multiple is the least of your problems.

Affordability is more than your salary

Income is only one input. Before you commit, also check:

1. Cash for costs other than the downpayment. For a bank loan, at least 5% of the price must be cash. Stamp duty is due soon after you sign, so have the money ready. Legal fees and renovation come on top.
2. How stable the income is. A household that depends on one income, or on commission and bonuses, should aim well below the limits. Banks count variable income at only 70%, and so should you.
3. Your buffer. Keep six months of mortgage payments and living costs in cash after the purchase.
4. Timing and rules. Stamp duty, LTV limits and Seller’s Stamp Duty can change. A home bought from 4 July 2025 carries SSD if you sell within four years.

Four levels of affordability

Property Soul also put buyers, especially investors, into four groups. They still work:

Level	What it looks like
Very affordable	You could pay mostly in cash. A loss would hurt but not change your life.
Highly probable	You pass 3/3/5 and have income that does not depend on one pay cheque.
Merely stretchable	You fail one or more tests. Every rate rise, vacancy or job change worries you.
Barely reachable	You struggle to find the downpayment, and someone suggests “a way to help”. Stop here.

Aim for the first two. If you are in the third group, wait, save, or buy a cheaper home. If you are in the fourth, the answer is no for now.

Bottom line

Banks will lend up to the TDSR and MSR limits, but those limits tell you what is legal, not what is wise. Use the 3/3/5 rule as your own stress test. Have 30% in capital. Keep the mortgage under one-third of income at a 4% rate. Treat five times income as a warning line, not a target. Run your own figures in our mortgage calculator, then read how banks size loans in our TDSR and MSR guide and how much you can borrow on an HDB loan.
