A CPF housing loan is not a separate loan product. It is your own Ordinary Account (OA) money paying down a home loan and the upfront costs that come with an HDB flat or condo. In 2026 your OA still earns 2.5% a year, and every dollar you pull out for property keeps accruing that 2.5% as a debt to yourself, payable when you sell. So the real question is not whether you can use CPF. You almost always can. It is how much you should, because the cheapest money you own is the OA money that stays put and compounds. This guide walks through the exact 2026 limits, what CPF covers, the accrued interest maths, and the cases where cash genuinely beats CPF.
Your CPF OA can be tapped at three points in a home purchase: the downpayment, the one-off legal and stamp duty costs, and the recurring monthly mortgage instalment. The OA is the only account you can use for property. Your Special, MediSave and Retirement Account savings stay locked for retirement and healthcare.
What CPF can and cannot touch is fixed by rule, not by your bank. The split below is current as of June 2026.
The downpayment rule depends entirely on whether you take the HDB concessionary loan or a bank loan. This is the single biggest fork for first-time buyers, and it decides how much of your own cash you have to find on day one.
On the HDB loan the Loan-to-Value (LTV) limit is 75% as of 2026, so the downpayment is 25%. None of that 25% has to be cash. You can settle the whole downpayment from your OA if the balance is there. On a bank loan the LTV is also capped at 75%, but the first 5% of the price must be paid in hard cash. The next 20% can come from OA. We compare the two loan structures in full in HDB loan vs bank loan, and you can size the monthly repayment with the mortgage calculator.
| Loan type | Total downpayment | Minimum cash | Payable from CPF OA |
|---|---|---|---|
| HDB concessionary loan | 25% of price | S$0 | Up to 25% |
| Bank loan (HDB or condo) | 25% of price | 5% of price | Up to 20% |
Beyond the downpayment, CPF sets a ceiling on the total OA you can sink into a property across its lifetime. Three terms decide that ceiling, and they trip people up because they sound similar.
Get these right and you will know exactly when CPF stops and cash takes over.
The Valuation Limit (VL) is the lower of the purchase price or the property's valuation at the time of purchase. The Withdrawal Limit (WL) is the hard cap on total OA you can use, and for properties bought with a bank loan it sits at 120% of the VL.
For an HDB flat bought with an HDB concessionary loan there is no Withdrawal Limit. You can use your OA to clear the loan in full. The 120% cap only applies once a bank loan is involved, whether the property is an HDB flat, an executive condo or a private condo.
Once your CPF use reaches the VL on a bank-loan property, you can only keep using OA up to the 120% cap if you have set aside the Basic Retirement Sum (BRS) across your OA and SA (or your Retirement Account if you are 55 or older). For members turning 55 in 2026 the BRS is S$110,200, the Full Retirement Sum is S$220,400, and the Enhanced Retirement Sum is S$440,800, all confirmed by the CPF Board.
If you are buying a second or subsequent property, the BRS (or FRS for those 55 and above) must be set aside before you can use any OA at all. Definitions for these thresholds live in our glossary entries for CPF Ordinary Account and Basic Retirement Sum.
If the property's remaining lease cannot cover the youngest buyer to age 95, your usable CPF is pro-rated downward. Once total CPF use across all owners hits that pro-rated limit, you cannot use any more OA, even if you have set aside the BRS. That makes older resale flats and short-lease condos worth a careful CPF check before you commit.
This is the part most buyers underweight. Every dollar of OA you use for property is treated as a loan from your future self, and it accrues interest at 2.5% a year, compounded annually. When you sell, you must return the principal plus all that accrued interest to your CPF before you see a cent of cash profit.
The number compounds quietly. Use S$150,000 of CPF on a flat and hold it for five years, and you owe roughly S$20,000 in accrued interest on top, based on the 2.5% rate. Use S$300,000 at the start of a 25-year loan and the accrued interest alone can run past S$200,000 by the end. The money does not vanish. It goes back into your CPF and resumes compounding for retirement. But it does shrink the cash you walk away with at sale.
In a worst case, a long hold with heavy CPF use can leave you with a negative sale, where the price minus the outstanding loan does not cover the CPF refund. CPF does not chase you for a top-up if you sell at or above market value in an arm's length deal, but you walk away with little or no cash. You can model the OA you would otherwise keep growing with the compound interest calculator.
| CPF OA used | After 5 years | After 15 years | After 25 years |
|---|---|---|---|
| S$100,000 | ~S$13,100 | ~S$44,800 | ~S$85,400 |
| S$200,000 | ~S$26,300 | ~S$89,500 | ~S$170,800 |
| S$300,000 | ~S$39,400 | ~S$134,300 | ~S$256,200 |
Here is the trade-off in plain terms. OA money left untouched earns 2.5% a year, tax-free and guaranteed. A bank mortgage in mid-2026 costs somewhere around 1.4% to 1.9% a year for the loan portion. If your loan rate is below 2.5%, the OA you keep in the account out-earns the interest you pay on the loan. Paying the instalment in cash and leaving OA to compound is the quietly profitable move.
It is not a free lunch in every case. Cash you sink into a mortgage is cash you cannot invest elsewhere, and not everyone has the spare cash flow. The decision really turns on three things: your loan rate versus 2.5%, whether you have a cash buffer of three to six months, and how long you plan to hold the property.
Compare the structural cost of each loan in HDB loan vs bank loan, and if you are weighing flat versus condo, HDB vs condo sets out the wider numbers.
Concrete numbers make the rules click. Both examples assume June 2026 settings and a 75% LTV.
No. There is no separate CPF housing loan product. The phrase refers to using your CPF Ordinary Account savings to pay for a home, the downpayment, stamp duty and monthly instalments, on either an HDB concessionary loan or a bank loan. The actual loan comes from HDB or a bank, not CPF.
For an HDB flat on an HDB loan there is no cap, so OA can clear the loan in full. For any property on a bank loan, total OA use is capped at 120% of the Valuation Limit, and you must set aside the Basic Retirement Sum of S$110,200 (2026) before using OA beyond the Valuation Limit.
Yes, when you sell. You must refund the principal you withdrew plus accrued interest at 2.5% a year compounded, back into your CPF. The refund resumes earning interest for retirement. If you are 55 or older it first tops up your Retirement Account toward the Full Retirement Sum.
If your loan rate is below the 2.5% your OA earns, paying in cash and leaving OA to compound generally leaves you better off, provided you keep a three to six month cash buffer. If cash flow is tight or you can invest spare cash above 2.5%, using CPF for the instalment is reasonable.
