HDB Valuation vs Purchase Price — What's the Difference?
They're two different numbers, and the gap between them can cost you tens of thousands in cash. Here's what you need to know.
Answer: Valuation is HDB's official assessment of the flat's worth. Purchase price is what you agree to pay the seller. If the price is higher than the valuation, the gap is called COV (Cash Over Valuation) — and it must be paid in cash only. Your loan amount and CPF usage are both capped at the valuation, not the price.
Valuation vs Price at a Glance
| Factor | Valuation | Purchase Price |
|---|---|---|
| Set by | HDB-appointed valuer | Buyer and seller (negotiated) |
| Purpose | Determines loan & CPF limits | What you actually pay |
| Can be higher? | — | Yes — COV applies |
| Loan based on | Lower of valuation or price | — |
| CPF usage limit | Up to valuation | — |
| Grant eligibility | Based on valuation | — |
How COV (Cash Over Valuation) Works
Example: Agreed price $530,000, valuation $500,000
| Component | Amount | Payment Source |
|---|---|---|
| HDB valuation | $500,000 | — |
| Agreed price | $530,000 | — |
| COV | $30,000 | Cash only |
| Loan (80% of valuation, HDB loan) | $400,000 | HDB loan |
| Down payment (20% of valuation) | $100,000 | CPF OA / cash |
| Total cash needed (min) | $30,000 | COV portion (if CPF covers down payment) |
With an HDB loan (80% LTV), the loan is 80% of the valuation. Down payment can come from CPF. But COV is always cash.
Why Valuation Matters
1. Loan amount is capped at valuation
Whether you take an HDB loan (80% LTV) or bank loan (75% LTV), the loan is calculated on the lower of valuation or purchase price. A low valuation means a smaller loan and more cash out of pocket.
2. CPF usage is capped at valuation
You can only use CPF OA funds up to the valuation limit (minus the loan amount). Any amount above valuation — the COV — must come from cash.
3. Grants are based on valuation
CPF housing grants (EHG, PHG) are applied against the valuation amount, not the purchase price. If the price exceeds valuation, the grant does not cover the COV.
4. COV can derail your budget
In a hot market, COV of $20,000–$50,000 is common. Some flats in desirable locations have seen COV above $80,000. This is cash you need on top of everything else.
Current Market — Is COV Common?
Yes. In the current resale market, the majority of HDB resale transactions involve some degree of positive COV. Popular locations (Queenstown, Bishan, Toa Payoh, Bukit Merah) regularly see COV of $20,000–$60,000. Mature estates with remaining leases above 70 years tend to command higher COV.
That said, not every flat has COV. Flats in less popular locations, older flats with shorter remaining leases, or higher-floor units priced at market rate may transact at or near valuation.
Always budget for potential COV. Factor in at least $20,000–$30,000 as a cash buffer when planning your HDB resale purchase.
Tips for Dealing with COV
- • Negotiate. The asking price is not final. Use recent comparable transactions as leverage.
- • Check comparables. Look at recent resale prices on the same block or nearby blocks on HDB's resale portal.
- • Budget for it. Don't assume zero COV. Set aside cash specifically for the COV portion.
- • Consider timing. COV tends to be higher in a rising market. If the market cools, COV narrows.
- • Get the OTP first. You only get the official valuation after submitting the resale application with the OTP. You can't know the exact COV before that.

FAQ
What is HDB valuation?
HDB valuation is the official assessed value of a resale flat, determined by HDB-appointed valuers. It is based on recent comparable transactions, flat condition, remaining lease, location, and floor level. The valuation is valid for the specific transaction and is conducted after you have the Option to Purchase (OTP).
What is Cash Over Valuation (COV)?
COV is the difference between the agreed purchase price and the HDB valuation, when the price is higher. For example, if the valuation is $500,000 and the agreed price is $530,000, the COV is $30,000. This $30,000 must be paid in cash — you cannot use CPF or a loan for it.
Can I use CPF to pay for COV?
No. COV must be paid entirely in cash. CPF can only be used up to the valuation amount, not the purchase price. This is one of the biggest cash traps for HDB resale buyers.
How is the HDB valuation done?
After you receive the OTP and submit your resale application, HDB appoints a valuer to assess the flat. The valuation considers recent resale prices of comparable flats, the flat condition, remaining lease, floor level, and facing. You typically receive the valuation within 2 weeks of application.
What if the valuation is higher than the purchase price?
This is rare but possible. If the valuation is higher than your agreed price, the loan and CPF limits are still based on the lower of the two — the purchase price. You do not benefit from an over-valuation in terms of loan amount.
