How to Use CPF for Housing in Singapore 2026: OA, Valuation Limit, and Accrued Interest

Last reviewed: June 2026

You use CPF for housing mainly through your Ordinary Account, which can pay your down payment, monthly mortgage instalments, stamp duty, and legal fees, subject to the Valuation Limit and Withdrawal Limit. Your CPF Ordinary Account is one of the most useful tools for buying a home in Singapore, but it comes with rules that most buyers do not fully understand until they are sitting in front of their lawyer. This guide explains what your OA can pay for, how the Valuation Limit and Withdrawal Limit work, what accrued interest means for your sale proceeds, and how CPF Housing Grants reduce your out-of-pocket cost.

What Can Your CPF OA Pay For?

Your CPF Ordinary Account can be used for several housing-related expenses:

• Down payment. The OA can pay the down payment on both HDB flats and private property, subject to the minimum cash down payment requirement. For HDB purchases financed by a bank loan, at least 5% of the purchase price must be paid in cash.
• Monthly mortgage instalments. You can use your OA balance to pay your monthly loan instalments, up to the limits described below.
• Stamp duty. Buyer's Stamp Duty (BSD) for both HDB and private property can be paid from your OA.
• Legal fees. Conveyancing fees for the purchase can be paid from CPF OA.
• Housing-related costs. Home protection insurance (HPS) premiums for HDB purchasers are also paid via OA.

The Valuation Limit: What It Means in Practice

The Valuation Limit (VL) is the lower of the purchase price and the market value of your property at the time of purchase. It is the primary cap on how much CPF you can use for housing.

For most buyers purchasing at or below market value, the purchase price and market value are the same, so the VL equals the purchase price. If you buy above valuation, the VL is capped at the lower market value, and you need to top up the difference in cash.

Here is a concrete example. If you buy a resale HDB flat for SGD 600,000 and the HDB values it at SGD 580,000, your VL is SGD 580,000. You can use CPF for housing payments up to a cumulative total of SGD 580,000. The SGD 20,000 gap must be paid in cash.

The Withdrawal Limit: When You Can Go Beyond the VL

Once your cumulative CPF housing withdrawals reach the Valuation Limit, you cannot simply continue drawing on your OA by default. To use CPF beyond the VL (up to 120% of VL, which is the Withdrawal Limit), you must have set aside at least the Basic Retirement Sum (BRS) in your CPF accounts.

The BRS for 2026 is SGD 106,500. If your combined OA, SA, and RA balance meets this threshold, you can continue using OA for housing payments beyond the VL, up to the Withdrawal Limit of 120% of VL.

Accrued Interest: The Hidden Cost You Must Repay

This is where many sellers get an unpleasant surprise. When you withdraw CPF funds for housing, CPF Board tracks what that money would have earned had it stayed in your OA (currently 2.5% per annum, compounded annually). This is called accrued interest.

When you sell your property, you must refund both the principal withdrawn and all accumulated accrued interest back to your CPF OA. The refund is not a penalty but a restoration of your retirement savings to what they would have been without the withdrawal.

The accrued interest compounds over time. If you withdrew SGD 200,000 ten years ago, the accrued interest alone would be approximately SGD 200,000 x (1.025^10 - 1) = SGD 28,008. Your CPF refund on sale would be SGD 228,008 before the outstanding mortgage is settled.

What Happens If the Sale Proceeds Are Not Enough?

If your sale proceeds after repaying the outstanding mortgage are not sufficient to cover the full CPF refund, you only need to refund what the proceeds allow. CPF Board does not require a cash top-up to cover the shortfall. The shortfall reduces your CPF balance, which affects your CPF LIFE payouts later, but it does not create a cash debt.

This situation sometimes arises when property values fall significantly or when buyers overpay relative to the VL and have drawn heavily from CPF over many years. Checking your projected accrued interest before you decide to sell helps you understand your net cash position from the sale.

CPF Housing Grants for HDB Buyers

For HDB flat buyers, CPF Housing Grants reduce the effective price you pay and are credited directly to your OA. The main grants in 2026 are:

Grants credited to your OA are treated the same as your own CPF contributions for housing purposes: they count toward the VL and attract accrued interest. When you sell, the grant principal and its accrued interest are also refunded to your OA.

What Happens to Your CPF When You Turn 55?

At age 55, CPF Board creates a Retirement Account (RA) and transfers funds from your SA and OA to meet the Full Retirement Sum (FRS) or Basic Retirement Sum (BRS). The amount transferred to the RA comes first from the SA, then from the OA.

If you are still servicing a home loan at 55, you can continue using your OA for monthly instalments. However, if the transfer to the RA at 55 depletes your OA significantly, your CPF top-ups for housing will slow or stop and you may need to pay instalments in cash. Planning ahead for this transition avoids surprises.
