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.
Update, 14 October 2026: IRAS says you pay Additional Buyer's Stamp Duty in cash first and can then be reimbursed from your CPF, not that CPF cannot be used for it, and on a resale flat with an HDB loan your OA covers the whole loan only if you can set aside the Basic Retirement Sum. 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. Your OA is the account that pays for property; Special, MediSave and Retirement Account savings are kept 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 October 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%. Apart from the option fee, the option exercise fee on a resale flat and any price above the valuation, none of that 25% has to be cash. You can settle the downpayment from your OA if the balance is there; in fact, on an HDB loan your OA savings must go towards the purchase first, though you can choose to keep up to S$20,000 in the account. 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 | Option fee only | 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.
CPF calls its ceiling the CPF housing limit; older guides call it the Valuation Limit (VL) and Withdrawal Limit (WL). On a bank loan it is the lower of the purchase price or the valuation, plus up to another 20% of that figure if you have set aside the Basic Retirement Sum, so 120% at most. Stamp duty, legal fees and upgrading costs paid from CPF do not count towards it.
For a new flat bought from HDB with an HDB loan, the limit is the purchase price or the loan, so your OA can clear the loan in full. A resale flat on an HDB loan is different: your OA can cover the whole loan only if you can set aside the Basic Retirement Sum, and otherwise stops at the lower of price or valuation.
Once your CPF use reaches the lower of price or valuation on a bank-loan property or a resale flat, you can only keep using OA if you have set aside the Basic Retirement Sum (BRS), which you can meet with OA, Special Account and Retirement Account savings. 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 under 55, the BRS you set aside is half the Full Retirement Sum in force that year, which rises every year.
If you are buying a second or subsequent property, you must set aside the BRS before using any OA if you already own a property whose lease lasts you to age 95, or the FRS if you do not. 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, and you can use CPF at all only if at least 20 years of lease remain. CPF's own example: two 25-year-olds buying a S$550,000 flat with 65 years left can use up to S$495,000, or 90%, because the lease lasts until they are 90. Once total CPF use across all owners hits that limit, you cannot use any more OA. 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$89,700 | ~S$170,800 |
| S$300,000 | ~S$39,400 | ~S$134,500 | ~S$256,200 |
Here is the trade-off in plain terms. OA money left untouched earns 2.5% a year, tax-free and guaranteed, and if you are under 55 the first S$20,000 of it also counts towards CPF's extra 1% on the first S$60,000 of your combined balances (paid into your Special or Retirement Account), so that slice earns up to 3.5%. An HDB loan charges 2.6%. Bank floating packages are priced at the 3-month SORA plus a spread, such as DBS's 3M SORA + 0.75% package, so compare your own loan rate with the OA's 2.5%; our mortgage broker guide tracks current packages. 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 October 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 a new flat bought from HDB with an HDB loan, OA can clear the loan in full. For a resale flat on an HDB loan, or any property on a bank loan, OA stops at the lower of the price or valuation unless you set aside the Basic Retirement Sum (S$110,200 in 2026); with it, a bank-loan buyer can use up to 20% more, and a resale-flat buyer on an HDB loan can use OA for the whole loan. Two more limits apply: CPF use is pro-rated when the lease cannot cover the youngest buyer to age 95, and on a second property you must set aside the BRS or FRS before using any OA.
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 to your required retirement sum, and the rest stays in your OA.
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.
