The price you negotiate and the number your financing is built on are two different figures. When they diverge, the gap is settled in cash, by the buyer on the way in or by the seller on the way out.
Banks and HDB apply the loan-to-value (LTV) limit to the lower of the purchase price or the official valuation. If a flat is valued at S$620,000 and you agree to pay S$650,000, the 75% ceiling is calculated on S$620,000, not S$650,000.
That S$30,000 difference is Cash Over Valuation (COV). It cannot be financed, and it cannot be withdrawn from your CPF Ordinary Account, because the OA housing withdrawal limits are themselves tied to the valuation. COV comes from cash savings only. This is the point at which the mortgage stops being the variable you can adjust: no loan package, tenure or rate changes the fact that your real cash-down requirement rises dollar for dollar with every dollar of COV.
The table below shows the same flat, valued at S$620,000, bought at three different prices, assuming a 75% LTV ceiling and no other outstanding housing loan.
| Scenario | Agreed price (S$) | Loan base, lower of two (S$) | Maximum 75% loan (S$) | Total upfront cash + CPF (S$) |
|---|---|---|---|---|
| Above valuation | 650,000 | 620,000 | 465,000 | 185,000 |
| At valuation | 620,000 | 620,000 | 465,000 | 155,000 |
| Below valuation | 580,000 | 580,000 | 435,000 | 145,000 |
The loan is identical in the first two rows. Paying S$30,000 over valuation buys you nothing extra in financing, it simply adds S$30,000 to the cash you must produce at completion.
Take the S$650,000 purchase on a S$620,000 valuation. Stated assumptions: 75% LTV, no other outstanding housing loan, a 25-year tenure, and an assumed 2.6% rate (the HDB concessionary rate is pegged at 0.1 percentage points above the OA rate).
If you take a bank loan, at least 5% of the loan base must be cash, so S$31,000 cash plus up to S$124,000 from CPF OA, then the S$30,000 COV on top. Minimum cash at completion is therefore S$61,000, not S$31,000. With an HDB loan the 25% can come entirely from CPF OA, but the COV still cannot.
Monthly repayment on S$465,000 over 25 years at 2.6% is S$2,110. Note what the COV did not change: the instalment. You paid S$30,000 in cash for no additional financing and no additional asset value on paper.
The sequence matters. For an HDB resale flat, the buyer can only request a valuation after the Option to Purchase has been granted. You negotiate blind, then find out whether you have committed to a COV and how large it is.
The practical response is to form your own view of valuation from recent transacted prices in the same block and flat type before you make an offer, and to hold a cash buffer for the gap. If you have no buffer, your maximum offer is the price you believe the valuation will support.
Sale proceeds are not yours first. The outstanding mortgage is discharged, then you must refund to CPF the principal you withdrew plus accrued interest, currently 2.5% per annum on the OA. On a flat held for a decade or more, accrued interest alone can run into tens of thousands of dollars.
When proceeds after the loan are not enough to make the full CPF refund, that is a negative sale. If you sold at or above market valuation, you generally do not have to top up the shortfall in cash. If you sold below valuation, you must top up the difference in cash.
Mirror the earlier example. A flat valued at S$620,000 is sold at S$580,000, with S$200,000 of CPF principal plus accrued interest to be refunded. The S$40,000 below-valuation gap is the figure CPF looks at, and the required cash top-up is the lower of that gap and the actual refund shortfall. Accepting a quick sale S$40,000 under valuation is not a S$40,000 haircut on your profit, it can be a S$40,000 cheque you write at completion.
If you buy at S$580,000 against a S$620,000 valuation, you hold paper equity immediately, but the loan base is the price. The 75% ceiling gives you S$435,000, not S$465,000, so your cash outlay falls but your loan falls too.
Budget from the valuation, not the headline price. That single discipline sets both your maximum offer and the cash you need on hand at completion.
In Singapore's September 2026 forced auction of seized money laundering assets, only four condominium units at Martin Modern and Wallich Residence sold, totalling S$16.28 million, with individual prices between S$2.08 million and S$6.6 million. Fifteen other properties, including a S$25.3 million South Beach Residences penthouse and a Kaki Bukit factory, failed to sell or were withdrawn. The pattern shows liquidity and comparable pricing data, not scandal stigma, determined which assets cleared, with nothing above roughly S$7 million selling.

A property valuation report is a certified, date-specific estimate of market value prepared by a licensed valuer, and it is this figure, not the agreed price, that banks, HDB and CPF use to set loan-to-value limits, CPF usage caps and cash requirements. Because loans are based on the lower of price or valuation, any amount paid above the valuation must be covered entirely in cash, making the report the decisive number in financing, refinancing, and asset division cases.
