CPF OA vs SA for Property — Which Account Can You Use?
Your CPF has multiple accounts with different interest rates and rules for property. Here’s the full breakdown of what you can use, what you can’t, and why it matters.
Answer: Use CPF OA (Ordinary Account) for property — it earns 2.5% p.a. and can cover downpayment (20% portion), BSD stamp duty, monthly mortgage, and legal fees. CPF SA (Special Account) earns 4% p.a. and is primarily for retirement — it can only be used for property when OA is insufficient. SA shielding was closed in 2025, so using SA for property no longer shields it from the Retirement Account transfer at 55. OA usage is capped at 120% of Valuation Limit. When you sell, all CPF used must be refunded with 2.5% accrued interest.

The 120% Valuation Limit Rule
CPF OA usage for property is capped at 120% of the Valuation Limit (the lower of purchase price or market valuation). Once cumulative OA withdrawals hit this cap, remaining mortgage must be paid in cash.
| Property Value | Max CPF OA Usage (120%) | Covers Mortgage For |
|---|---|---|
| $500,000 | $600,000 | ~24 years of payments |
| $800,000 | $960,000 | ~23 years of payments |
| $1,000,000 | $1,200,000 | ~23 years of payments |
| $1,500,000 | $1,800,000 | ~22 years of payments |
Includes downpayment (20%), BSD, and monthly mortgage. Approximate coverage based on 3.5% rate.
The Accrued Interest Trap
When you sell, every dollar of CPF OA used for property must be refunded with 2.5% p.a. compounded interest. This reduces your cash proceeds from the sale.
| CPF Used | Refund After 5 Years | Refund After 10 Years | Refund After 15 Years |
|---|---|---|---|
| $100,000 | $113,141 | $128,008 | $144,830 |
| $200,000 | $226,282 | $256,016 | $289,660 |
| $300,000 | $339,423 | $384,025 | $434,490 |
Includes downpayment and cumulative mortgage payments. 2.5% p.a. compounded. Use the CPF Accrued Interest Calculator for your exact numbers.

FAQ
Can I use CPF SA to buy property?
Only if your OA balance is insufficient. CPF prioritises OA for housing. SA can only be used for property when your OA is not enough to cover the required amount. Even then, SA shielding was closed in 2025, so using SA no longer helps you avoid the Retirement Account transfer at 55.
Why is CPF OA the default for property?
OA (Ordinary Account) is designed for housing, education, and insurance. It earns 2.5% p.a. and has flexible withdrawal rules for property. SA (Special Account) is for retirement, earns 4% p.a., and CPF actively discourages using it for housing to protect retirement savings.
How much CPF OA can I use for property?
Up to 120% of the Valuation Limit (lower of purchase price or market value). For a $600K flat, max OA usage is $720K (covering downpayment, stamp duty, and up to ~23 years of mortgage). Once you hit 120%, remaining mortgage must be paid in cash.
Does using CPF OA for property affect my retirement?
Yes. Every dollar used for property must be refunded to OA when you sell, plus 2.5% p.a. accrued interest. At age 55, CPF transfers savings to the Retirement Account. If your OA is depleted by housing, less is available for retirement. Property can be pledged for BRS ($106,500) instead of FRS ($213,000).
Should I use OA or cash for my property downpayment?
Use CPF OA for the 20% portion (bank loan) to preserve cash. The 5% cash downpayment is mandatory and cannot come from CPF. Using OA preserves your liquidity but remember: OA earns 2.5%, and you must refund it with accrued interest when you sell.
