How Much Can I Really Afford? HDB to Condo in Singapore
By Daniel Wu, CEA Reg No: R070500C | Updated November 2026
The bank will tell you the maximum you can borrow. That is not the same as what you can afford comfortably.
For an HDB upgrader, affordability has 3 checks, in order:
What will the bank lend — TDSR, MSR, LTV, tested at 4%
What cash and CPF do you actually have on the day you buy — downpayment, stamp duty, CPF refund, resale levy
Can you still pay it if rates rise, or one income stops for 6 months?
If you pass 1 but fail 2 or 3, you cannot afford it yet — even if the bank says yes.
1. What will the bank lend? TDSR 55%, MSR 30%, tested at 4%
These are the MAS caps that decide your loan. They are the same caps I used in the New Launch guide, and they apply here too.
TDSR: 55% — all your monthly debt payments, including the new mortgage, car loan, personal loan and credit card minimums, must stay at or below 55% of gross monthly income.
MSR: 30% — for HDB flats and new ECs only, the mortgage alone is capped at 30% of gross income. Private condos use TDSR, not MSR. So MSR binds for an EC, TDSR binds for a resale condo.
Stress test: 4% — banks test the new loan at 4% a year, or the actual rate if higher, even if you are paying 2% today. That is the rule that catches most upgraders.
Variable income is haircut 30% — commission, bonus and rental are typically counted at 70% in the TDSR calculation, based on the last 12 months.
LTV: 75% on a first loan — at least 5% of the price in cash, a further 20% in cash or CPF. Full 75% only if tenure is 30 years or less and ends by age 65. If tenure is longer, or runs past 65, LTV drops to 55%.
At 4% over 30 years, the caps work out like this. Illustrative — my own arithmetic from the MAS caps, no other debt, 30-year tenure:
$10,000 gross monthly household income: TDSR caps all debt at $5,500 a month. That supports a loan of about $1.15m. At 75% LTV, that is a price of about $1.54m, with about $384,000 downpayment.
$12,000 gross monthly household income: TDSR caps all debt at $6,600 a month. That supports a loan of about $1.38m. At 75% LTV, that is a price of about $1.84m, with about $460,000 downpayment.
$16,000 gross monthly household income: TDSR caps all debt at $8,800 a month. That supports a loan of about $1.84m for a private condo. At 75% LTV, that is a price of about $2.46m, with about $614,000 downpayment. For a new EC, MSR caps the mortgage at $4,800 a month instead, which supports a loan of about $1.01m — a price of about $1.34m at 75% LTV. That is why the same income buys a much smaller EC than a resale condo.
Your own income, debts, age and tenure will change these numbers. Get a bank in-principle approval before you make an offer — it is free, and it is the only number that counts as a real loan offer.
2. The 3-step HDB to Condo framework
This is the framework from my old HDB to Condo page, rewritten with numbers. Use it in order. Do not skip Step 1 to look at showflats.
Step 1 — Financial Assessment. Work out your net sale proceeds first, not your HDB's asking price.
HDB sale price, minus outstanding HDB / bank loan
Minus CPF refund: every dollar you used from CPF Ordinary Account, plus accrued interest at 2.5% a year.
Source: CPF, accrued interest 2.5% p.a., compounded monthly.
Minus agent commission and legal fees on the sale
What is left is cash + CPF you can actually use for the next home. That is your real budget, not the sale price.
Step 2 — Timing the Market. Sell first, or buy first?
Sell first: you know exactly how much cash you have, and you pay no ABSD. Risk: you may need to rent in between, and prices can move while you wait.
Buy first: you buy the condo, then sell the HDB within 6 months to claim ABSD remission. Risk: you pay ABSD upfront — 20% for a Singapore Citizen buying a second property — and if your HDB does not sell in time, that ABSD is not refunded in full.
Source: IRAS, ABSD rates in force from 27 Apr 2023, Citizen second property 20%, third or later 30%.
Check your HDB MOP first: 5 years from TOP / purchase, depending on how you bought it. You cannot sell before MOP.
Source: HDB.
Step 3 — Exit Strategy. Plan the exit before you buy.
Who will buy this condo from you in 5–10 years? A family, an investor, a downgrader?
What is the lease left, the maintenance, the upcoming supply nearby?
What is your Seller's Stamp Duty clock? For private homes bought on or after 4 July 2025, SSD applies for 4 years, at 16% down to 4%.
If you cannot answer who the next buyer is, you are not buying an asset — you are buying a hope.
3. The true cost to own — it is not just the price
Price psf is not the cost. Add these before you decide:
Downpayment: 25% of the price, 5% in cash minimum. On $1.5m, that is $375,000 downpayment, $75,000 in cash. On $2m, that is $500,000 downpayment, $100,000 in cash.
Buyer's Stamp Duty: 1% on the first $180,000, 2% on the next $180,000, 3% on the next $640,000, 4% on the next $500,000, 5% on the next $1.5m, 6% above $3m.
On $1.5m, BSD is $44,600. On $2m, BSD is $69,600. On $1m, BSD is $24,600.
BSD is paid in cash, within 14 days of signing the Sale and Purchase Agreement in Singapore. It is not part of the loan.
ABSD, if this is a second property: 20% for a Citizen, 30% for a PR buying a second home, 60% for a foreigner.
Legal fees, valuation, mortgage insurance if applicable
Maintenance + property tax, every month, from day one
Renovation, furniture, and a buffer: 6–12 months of instalments if income drops or rates rise
CPF accrued interest on sale: when you sell your HDB, you must return the CPF you used, plus 2.5% a year accrued interest. For a couple who used $250,000 of CPF over 12 years, that accrued interest alone can exceed $78,000.
Source: CPF, 2.5% p.a. accrued interest; illustrative example from 2026 upgrader guides.
Resale levy — the cost most upgraders get wrong:
You pay a resale levy ONLY if you buy a second subsidised flat — a new BTO / SBF, or a new EC from a developer. Amount is fixed by the flat type you sold: $15,000 for 2-room, $30,000 for 3-room, $40,000 for 4-room, $45,000 for 5-room, $50,000 for Executive, $55,000 if your first subsidised home was an EC. Paid in cash or from sale proceeds, not from CPF or a loan. Source: HDB, resale levy, flats sold on or after 3 Mar 2006.
You do NOT pay a resale levy if you buy a private condo or landed home. If an agent tells you the levy applies to a resale condo, that is wrong.
4. Can I afford it comfortably? Use the one-third check
The bank may let you go to 55% TDSR. That does not mean you should.
Use the rule as a comfort check:
Have at least 30% of the price in cash + CPF, not just the 25% minimum
Keep the mortgage at or below one-third of monthly income at 4% — on $12,000 income, that is $4,000 a month, not the bank's $6,600 maximum
Keep 6–12 months of instalments in cash after you buy
And test it at 4%, not at today's rate:
On a $1m loan over 30 years, the instalment is about $4,774 a month at 4%, versus about $3,696 at 2%. That $1,078 a month difference is the buffer you need to be able to pay. Illustrative, my own arithmetic, 30-year tenure.
On a $1.38m loan, it is about $6,588 at 4%, versus about $5,101 at 2%.
Ask yourself, in writing:
What is my instalment at 4%, not 2%?
What happens if one income stops for 6 months?
Can I still pay BSD + downpayment + renovation without wiping out CPF / cash?
Am I buying because I can hold it 5–10 years, or because I hope to flip it at TOP?
If the answer to the last one is "flip", stop. SSD, BSD and holding costs will eat a short flip.
5. The traps I see most often with HDB upgraders
Underestimating true costs: maintenance, stamp duty, tax, legal, renovation — then having no buffer left.
Selling the HDB too early, or too late: selling too early leaves you renting and watching prices move; selling too late leaves you paying ABSD upfront with a 6-month deadline to sell.
Stretching to the bank maximum: at 55% TDSR with no buffer, one rate rise or one income drop puts you in trouble.
Buying on psf alone: a cheap psf on a small, odd-layout unit is not cheaper than a fair psf on a usable 3-bedder. Compare total quantum, usable space, lease, and who buys it next.
Forgetting the CPF refund: your HDB sale price is not your cash. After loan + CPF refund + accrued interest, the cash in hand is often much less than people expect.
If you want, DM "AFFORD" + your HDB type, your household income band, and whether you are looking at EC, new launch, or resale condo, and I will run the 3-step check with you — loan cap at 4%, net sale proceeds, and true cost to own.
