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 viewing a single showflat, you need four numbers: your maximum loan quantum under TDSR and LTV rules, your required down payment in cash and CPF, your stamp duty liability (BSD always, ABSD if applicable), and your total cash outlay at signing. Get these right and you can walk into any showflat with full confidence — walk in without them and you're committing to one of the largest financial decisions of your life on incomplete information.

## Number 1: How Much Can You Actually Borrow?

Your loan quantum is governed by two MAS rules with no exceptions. TDSR caps your total monthly debt obligations — mortgage, car loan, personal loan, credit card minimums — at 55% of gross monthly income, though 35–40% is the more comfortable working target. On a $12,000 household income at a 40% threshold, that's $4,800/month for all debt servicing; subtract an $800 car loan and $4,000/month remains for mortgage, which services roughly $890,000 in loan at 3.5% over 30 years. That's your true loan capacity — not the bank brochure's headline number.

| 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% down payment. It's 25% on a first property, and it jumps to 55% on a second — including the case of upgrading from HDB to condo while retaining an investment property. HDB upgraders selling their flat typically revert to first-property LTV (75%), but the sequencing of that sale against the purchase matters enormously for cash flow.

## Number 2 & 3: Down Payment and Stamp Duty

Down payment in real dollars, first vs second property+ Read more− Collapse

On a $1.5M first property, minimum down payment is $375,000 — $75,000 cash, $300,000 fundable from CPF Ordinary Account. The same purchase as a second property requires $825,000 down — $375,000 cash, $450,000 from CPF. Your CPF OA balance must be sufficient, and if you're above 55, the Basic Retirement Sum must be set aside first. Check your balance at cpf.gov.sg before shortlisting — don't assume.

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:

| Buyer Profile     | 1st Property | 2nd Property |
| ----------------- | ------------ | ------------ |
| Singapore Citizen | 0%           | 20%          |
| Singapore PR      | 5%           | 30%          |
| Foreigner         | 60%          | 60%          |

A Singapore Citizen buying a $1.5M second property pays $300,000 in ABSD alone, before down payment or any other cost — and it must be paid entirely in cash, not CPF, not the bank loan. For most upgraders, the practical answer is to sell the HDB before or simultaneously with the condo purchase, avoiding second-property classification. Sequencing that sale correctly is one of the most consequential decisions in the entire transaction.

## Number 4: Your Total Cash Outlay on Day One

For a Singapore Citizen buying a first $1.5M condo with a bank loan: cash component of down payment $75,000, CPF component $300,000, BSD $44,600 (CPF or cash), legal fees roughly $3,500 cash. Minimum cash needed at signing for a new launch with no renovation: approximately $78,500\. Total CPF deployed: roughly $344,600\. The cash ask on a first property is lower than most buyers fear, provided CPF OA is adequately funded — the real question is whether you hold $75,000–$100,000 in cash and $300,000+ in CPF OA.

## Can You Service the Monthly Mortgage?

Affordability isn't just the day of signing — it's every month for 25–30 years. A $1,125,000 loan costs $5,051/month at 3.5% over 30 years, requiring a minimum household income around $9,180/month to meet TDSR at 55%, or $12,600/month for the more comfortable 40% threshold. UOB Economics & Markets Research (January 2026) forecasts SORA 3M near 1.32% by end-2026, suggesting floating rates could ease toward 3.0–3.2%; fixed 2-year lock-ins were pricing at 2.8–3.2% in early 2026\. Always stress-test at 4.0% regardless — the point isn't pessimism, it's ensuring a rate move doesn't force a sale at the worst possible moment.

## The Discipline That Actually Matters

The players who run out of cash lose, regardless of how many properties they own — in Monopoly and in Singapore property alike. Paper gains mean nothing if monthly cash flow is strained and one unexpected event, retrenchment, medical, family change, forces a sale at the wrong time. The sustainable buyer doesn't borrow to the bank's maximum. They buy where the monthly mortgage sits comfortably within 40% of household income, six months of mortgage payments remain in liquid savings after purchase, and the decision still makes sense if prices stay flat for three years. That discipline, not loan size, separates buyers who build wealth from buyers who spend decades servicing debt on an asset that never works for them.

## James's Note

The most common mistake at the pre-commitment stage+ Read more− Collapse

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, payable entirely in cash — it cannot be funded through CPF or included in your bank loan. 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.
