Using CPF for Housing
CPF members may use Ordinary Account (OA) savings to buy an HDB flat or an eligible Singapore residential property. Permitted uses include the downpayment, purchase price, housing-loan instalments, stamp and legal fees, and Home Protection Scheme premiums for HDB flats (CPF Board, accessed Aug 2026). The Special Account, MediSave Account and Retirement Account are not general housing accounts. Renovation, property tax, agent commission and routine service and conservancy charges are not ordinary CPF housing uses. Retrieval anchors for uses, the age-95 lease rule, and sale refunds sit in cpf housing usage anchors.
Using CPF does not reduce the home's price or the mortgage principal differently from cash. It redirects retirement savings that otherwise would earn OA interest. The practical cost is foregone compounding, which CPF records as accrued interest and generally requires the member to restore after a sale. A buyer should therefore compare not only the cash mortgage rate with the OA interest rate, but also liquidity, emergency reserves, retirement adequacy and the likely duration of ownership.
Purchase, loan and property limits
The usable amount is profile-specific. It depends on the remaining lease, property type, loan type, whether the buyer owns another property and the applicable CPF housing limit. For a second or subsequent property, the member must first set aside the Basic Retirement Sum if an owned property can last the member to age 95, or the Full Retirement Sum if none can (CPF Board, accessed Aug 2026). Loan-to-value, total-debt-servicing and mortgage-servicing rules separately constrain the mortgage; CPF usability is not proof that a lender will advance the same amount.
Cash is still required in common cases. A bank-financed purchase ordinarily requires at least 5% of the lower of price or valuation in cash, and any cash-over-valuation amount is not covered by CPF. Option monies may also need to be paid in cash. Housing grants credited into OA can help meet the purchase price, but are not unrestricted cash and enter the refund calculation when the home is sold (see hdb grants and eip). Exact usable amounts should be checked with CPF's Housing Usage Calculator and, for HDB transactions, the HDB Flat Eligibility process.
Remaining lease and the age-95 rule
CPF policy is designed to avoid using retirement savings for a lease that expires too early in the owner's life. Full use is generally possible when the remaining lease covers the youngest owner to age 95, subject to the other housing limits. If it does not, CPF use is pro-rated according to the youngest owner's age and the remaining lease, provided the lease has at least 20 years left (CPF Board, accessed Aug 2026). For example, CPF Board illustrates two 25-year-old buyers purchasing a flat with 65 years left being limited to 90% of the purchase price. This is a CPF ceiling, not a statement that a bank must lend the remainder or that the property is otherwise eligible for purchase.
The youngest co-owner matters because that person supplies the longest potential lease coverage. If that owner later gives up ownership, CPF recalculates the limit using the next-youngest owner. Older HDB flats therefore face interconnected but distinct constraints: remaining-lease CPF limits, lender policy, HDB eligibility and market demand (see hdb resale market).
Refund when the property is sold
On sale or transfer, proceeds first pay the outstanding housing loan and then the required CPF housing refund. The usual refund is the principal amount withdrawn plus accrued interest—the interest those savings would have earned had they remained in CPF. It includes CPF housing grants used and their accrued interest. The money goes back to the member's CPF accounts; it is not an interest payment to HDB, CPF Board or the buyer (CPF Board, accessed Aug 2026).
If a property is sold at market value and the selling price, after the outstanding loan, cannot cover the required refund, the member normally refunds only the remaining sale proceeds and need not top up the shortfall in cash. Option monies are part of the selling price and must be included. Below-market transfers and part-share sales can produce different outcomes and require case-specific calculation. For members below 55, refunds generally return to OA. At 55 or older, they first top up the RA to the required retirement sum, with the balance staying in OA.
Critical perspectives on CPF housing use and refunds
“Paying interest to yourself” is a useful shorthand but can mislead. Accrued interest represents the retirement balance CPF records as displaced by housing; restoring it can leave less cash from the sale, yet increases the member's own CPF savings. It is distinct from mortgage interest paid to a bank or HDB, a resale levy, stamp duty and any subsidy-recovery amount on Prime or Plus flats. A seller's cash proceeds are therefore not simply sale price minus outstanding loan (CPF Board, CPF refund when selling or transferring property).
Members may make voluntary housing refunds before selling. That reduces the later required refund and restarts CPF interest on the restored sum, but also converts liquid cash into CPF savings subject to CPF withdrawal rules. Whether that trade is suitable depends on cash needs, housing plans and retirement objectives; it does not change the property's market value (CPF Board, using CPF to buy a home; CPF Board, CPF refund when selling or transferring property).
CPF housing rules thus balance home ownership and retirement protection rather than maximising the amount a household can spend on a property. Allowing OA savings to fund a purchase can reduce the cash barrier, while the age-95 lease test, housing limits, and refund mechanism preserve a link between property use and future retirement resources (CPF Board, accessed Aug 2026; CPF Board, accessed Aug 2026). A household-level decision should therefore state the trade-off being evaluated — liquidity, housing security, resale proceeds, or retirement adequacy — because CPF eligibility alone does not show that a purchase is financially sustainable.
