The Price Quantum Is the Wrong Number to Start With

Buyer Guides · Financing MechanicsThe Price Quantum Is the Wrong Number to Start With

You call the developer hotline, hear "$1.4M," and either feel relieved or deflated. That number tells you the size of the asset. It tells you nothing about what actually leaves your bank account and CPF the day you commit.

Direct Answer

Before you view a single showflat, you need four numbers: the most you can borrow under TDSR and LTV rules, your downpayment in cash and CPF, your stamp duty (BSD always, ABSD if it applies), and your total cash outlay at signing. Get these right and you can walk into any showflat with confidence. Walk in without them and you're making one of the biggest financial decisions of your life on incomplete information.

Number 1: How Much Can You Actually Borrow?

How much you can borrow is set by two MAS rules with no exceptions. TDSR caps all your monthly debt, including the mortgage, car loan, personal loans and credit card minimums, at 55% of gross monthly income, though 35% to 40% is a more comfortable target. On a $12,000 household income at 40%, that's $4,800 a month for all debt. Take off an $800 car loan and $4,000 a month is left for the mortgage, enough to service roughly $890,000 at 3.5% over 30 years. That's your real borrowing capacity, not the headline figure in a bank brochure.

Buyer Profile	Max LTV	Min Down Payment
1st residential property	75%	25% (5% cash)
2nd residential property	45%	55% (25% cash)
3rd+ property	35%	65% (25% cash)

Most buyers assume a flat 20% downpayment. It's 25% on a first property, and it jumps to 55% on a second, including when you upgrade from HDB to a condo while keeping an investment property. HDB upgraders who sell their flat usually go back to first-property LTV (75%), but the timing of that sale against the purchase makes a huge difference to your cash flow.

Number 2 & 3: Down Payment and Stamp Duty

Down Payment in Real Dollars, First vs Second Property

On a $1.5M first property, the minimum downpayment is $375,000: $75,000 in cash and $300,000 that CPF Ordinary Account savings can cover. As a second property, the same purchase needs $825,000 down: $375,000 in cash and $450,000 from CPF. Your OA balance has to be big enough, and if you're over 55, the Basic Retirement Sum has to be set aside first. Check your balance at cpf.gov.sg before you shortlist, rather than assuming.

Buyer's Stamp Duty applies to every purchase on a tiered scale (1% on the first $180,000, rising to 6% above $3,000,000, IRAS rates effective February 2023) and can be paid from CPF OA. On a $1.5M property, BSD totals $44,600. Additional Buyer's Stamp Duty is the number that actually changes the calculus for upgraders:

A Singapore citizen buying a $1.5M second property pays $300,000 in ABSD alone, before the downpayment or anything else, and it has to be paid upfront within 14 days of signing. For most upgraders, the practical answer is to sell the HDB flat before, or at the same time as, buying the condo, so the condo isn't treated as a second property. Getting that sequence right is one of the most important decisions in the whole deal.

Number 4: Your Total Cash Outlay on Day One

For a Singapore citizen buying a first $1.5M condo with a bank loan: $75,000 cash towards the downpayment, $300,000 from CPF, BSD of $44,600 (CPF or cash) and legal fees of about $3,500 in cash. Minimum cash at signing for a new launch, before renovation: about $78,500. Total CPF used: about $344,600. The cash needed for a first property is lower than most buyers fear, as long as your OA is well funded. The real question is whether you have $75,000 to $100,000 in cash and $300,000+ in your OA.

Can You Service the Monthly Mortgage?

Affordability isn't just about signing day. It's every month for 25 to 30 years. A $1,125,000 loan costs $5,051 a month at 3.5% over 30 years, which needs a household income of about $9,180 a month to fit within TDSR at 55%, or about $12,600 at a more comfortable 40%. Rates have fallen a lot since: by September 2026, 3-month SORA was about 1.19% and the cheapest packages were around 1.4% (PropertyNet.SG). Still stress-test at 4% or higher. That isn't pessimism. It's making sure a rate rise can't force you to sell at the worst moment. See our guide to current home loan rates for the details.

The Discipline That Actually Matters

The players who run out of cash lose, however many properties they own, in Monopoly and in Singapore property alike. Paper gains mean nothing if your monthly cash flow is stretched and one surprise, a retrenchment, a medical bill, a family change, forces a sale at the wrong time. Sustainable buyers don't borrow the bank's maximum. They buy where the mortgage sits comfortably within 40% of household income, they keep six months of mortgage payments in cash after buying, and the purchase still makes sense if prices stay flat for three years. That discipline, not the size of the loan, separates buyers who build wealth from those who spend decades paying off a home that never works for them.

James's Note

The Most Common Mistake at the Pre-Commitment Stage

Buyers check their CPF balance but forget to subtract the amount ring-fenced for the Basic Retirement Sum if they're above 55, or forget that CPF used for a previous property must be refunded with accrued interest if that property sells before the next purchase. I run a full CPF audit for every client before we shortlist anything.

Frequently Asked Questions

What's the minimum down payment for a first condo purchase in Singapore?+

25% of the purchase price, of which 5% must be cash and the remainder can come from CPF Ordinary Account, subject to your OA balance and, if you're above 55, the Basic Retirement Sum set-aside requirement.

How much ABSD will I pay on a second property as a Singapore Citizen?+

20% of the purchase price, due within 14 days of signing. Budget to pay it upfront in cash; ask CPF whether any of your OA savings can reimburse it afterwards. On a $1.5M second property, that's $300,000 before any other cost.

What income do I need to service a $1.125M mortgage?+

At 3.5% over 30 years, monthly payments run $5,051, requiring roughly $9,180/month household income to meet the 55% TDSR ceiling, or $12,600/month to stay within the more comfortable 40% target.

Can I use CPF to pay stamp duty on my condo purchase?+

Yes, Buyer's Stamp Duty can be paid from CPF Ordinary Account, which meaningfully reduces the cash needed at signing. ABSD, where applicable, must be paid in cash and cannot be funded from CPF.

What's the safest way to size a mortgage relative to income?+

Keep the monthly mortgage within 40% of household income rather than the 55% regulatory ceiling, hold six months of mortgage payments in liquid savings after purchase, and stress-test affordability at a 4.0% interest rate regardless of current rates.
