CPF is the quiet engine behind most Singapore home purchases — and the most misunderstood. Used well it makes a home affordable; used carelessly it can leave you with little cash when you sell. Here's how CPF property usage actually works in 2026.
Which CPF account you can use
You buy property using your CPF Ordinary Account (OA) — not your Special or MediSave accounts. The OA can fund part of the downpayment and the monthly mortgage instalments for both HDB flats and private property, subject to the limits below.
Downpayment: cash vs CPF
For a private property with a bank loan (75% LTV), the 25% downpayment splits into a minimum 5% in cash and the remaining 20% from cash or CPF OA. For HDB flats financed with an HDB loan, the downpayment can largely come from CPF. Knowing this split early tells you how much actual cash you need on completion day.
The Valuation Limit and Withdrawal Limit
Two ceilings govern how much CPF you can pour into a property:
- Valuation Limit (VL): the lower of the purchase price or valuation at the time of purchase. You can use CPF OA up to the VL relatively freely.
- Withdrawal Limit (WL): 120% of the VL. To continue using CPF beyond the VL up to the WL, you must first set aside the applicable Basic Retirement Sum in your CPF. This protects your retirement savings from being entirely consumed by housing.
For most buyers within their means, these limits never bite. They matter most for those stretching to the edge of affordability — which is itself a signal to reconsider the budget.
Accrued interest — the part people forget
This is the single most important CPF concept for sellers. Every dollar of CPF OA you use for your home is money that would have earned OA interest (currently 2.5% per annum) had it stayed in your account. When you sell, you must refund to your CPF both the principal you used andthe accrued interest you “owe yourself.”
Over 15–20 years, accrued interest compounds into a large sum. If your sale price barely exceeds your outstanding loan plus the CPF refund, you can walk away with little or no cash — a “negative sale” in cash terms even if the property nominally rose in value. Always model the CPF refund before you sell, not after.
What happens to the CPF refund when you sell
The principal and accrued interest go back into your OA, where they continue earning interest and can be used for your next property. The money is not lost — it returns to your retirement savings. But it is not spendable cash, which is why upgraders must separate “sale proceeds” from “cash in hand.”
CPF and your home loan
You can service monthly instalments from CPF OA, freeing cash flow — but doing so increases the accrued interest you'll repay later. Some buyers deliberately pay in cash to preserve CPF's compounding, especially when OA interest exceeds their mortgage rate. There's no universal answer; it depends on your rate, cash position, and goals.
Using CPF for an older leasehold property
CPF usage is restricted for properties with a remaining lease that does not cover the youngest buyer to age 95. For shorter-lease HDB flats and older leasehold homes, the amount of CPF you can use is pro-rated or capped — an important check before committing to an ageing leasehold unit.
Plan your CPF usage as part of the whole picture
CPF, financing, and stamp duty all interact — a smart buyer plans them together. As Senior Director of Agency at ERA Realty Network (CEA Reg No. R045215J), leading the #KND team of 400+ agents, I help clients model their real cash position, CPF refund, and accrued interest before they buy or sell, so there are no surprises at completion.
