The one-sentence summary
Your CPF Ordinary Account (OA) can pay for your downpayment, monthly instalments and some fees — but it is capped by the Valuation Limit (and, for private property, the Withdrawal Limit of 120%) and you may have to refund the amount plus accrued interest when you sell.
This page answers the question Singapore buyers type into search every single day: "how much CPF can I actually use to buy a home?" Every figure below is in SGD and drawn from official CPF Board, HDB and URA guidance.
Part 1 — The three limits that rule everything
1. Valuation Limit (VL)
The lower of the purchase price or market value at the time of purchase. For an HDB flat bought with an HDB concessionary loan, your combined CPF usage (plus outstanding loan) is capped at the VL.
2. Withdrawal Limit (WL)
For private residential property, the WL is generally 120% of the Valuation Limit, letting you draw more CPF while servicing a private loan — but with the same refund obligation.
3. The Refund (accrued interest)
When you sell, the CPF you used plus accrued interest is generally returned to your CPF account before you receive cash proceeds. Exception: if you are 55 or older selling your last property, you may keep the refund as cash.
| Term | What it caps | Typical cap |
|---|---|---|
| Valuation Limit (VL) | CPF + outstanding loan (HDB) | Lower of price or market value |
| Withdrawal Limit (WL) | CPF usage (private) | 120% of VL |
| Refund on sale | Cash you walk away with | CPF used + accrued interest |
Part 2 — Worked examples in SGD
Example A — First-time buyer, resale 4-room HDB at SGD 500,000
Purchase price SGD 500,000 · Market value SGD 495,000 → VL = SGD 495,000.
With an HDB concessionary loan, you may use your OA up to the VL of SGD 495,000 (combined with the loan). On sale, everything drawn from OA plus accrued interest is refundable.
Example B — Upgrading to a condo at SGD 1,600,000
Purchase price SGD 1,600,000 · Market value SGD 1,580,000 → VL = SGD 1,580,000.
Withdrawal Limit (private) = 120% × 1,580,000 = SGD 1,896,000. You may draw OA up to the WL while servicing a bank loan — but you will still need cash for the downpayment balance, ABSD (if applicable) and fees. On sale, refund CPF-used-plus-interest first.
Takeaway: The limit is generous on private property, but the cash requirement remains real. Housing is never 100% CPF-funded.
Part 3 — CPF vs cash: which should you use?
Use CPF when
- Your loan rate is higher than your OA interest rate (paying down the loan with CPF "saves" more).
- You are buying for the long term.
- You want to minimise cash outlay today.
Use cash when
- You may sell within a few years — cash avoids the refund-and-interest clawback.
- You are near retirement and want to protect your OA.
- Your OA interest (~2.5% base) is more valuable than a low-cost loan's flexibility.
Part 4 — The refund on sale, explained calmly
- Pay off outstanding housing loans.
- Refund CPF used plus accrued interest to your CPF account (unless exempted).
- Receive the remaining cash proceeds.
Small exception that matters: If you sell your last residential property and are 55 or older, you may be allowed to keep the refundable amount as cash, subject to CPF conditions.
Common question — "Do I get my CPF interest back?" Yes. Accrued interest is credited back into your OA or retirement plan — it is not lost, it is just not cash in hand at sale time. Plan around that.
Part 5 — Common mistakes to avoid
- Assuming 100% CPF coverage. You will almost always need cash.
- Ignoring accrued interest when planning an upgrade.
- Emptying your OA without preserving retirement headroom.
- Funding a short-horizon flip with CPF — the refund surprise is real.
- Not checking residency/citizenship implications (PR vs citizen) for ABSD and CPF use.

Frequently Asked Questions
How much CPF can I use for a resale HDB flat in Singapore?
Your combined CPF usage plus outstanding HDB loan is capped at the Valuation Limit — the lower of the flat's purchase price or market value.
What is the Withdrawal Limit (120%) for private property?
For private residential property you may use CPF up to 120% of the Valuation Limit while servicing a housing loan, giving more headroom but with the same refund obligation on sale.
Is it better to use CPF or cash for my home loan?
Use CPF when your loan rate exceeds your OA interest rate and you plan to hold long-term; use cash if you might sell soon or want to preserve retirement savings. Model your own numbers.
What is CPF accrued interest and do I have to pay it back?
Accrued interest is the interest your Ordinary Account would have earned on used CPF. On sale it is credited back to your CPF account, reducing cash proceeds, except for certain over-55 last-property sales.
Can foreign PRs use CPF to buy property in Singapore?
PRs can use CPF for private property and resale HDB subject to residency-based caps and ABSD rules. Foreigners without CPF must fund with cash and bank financing.
