Cash Over Valuation in Singapore: COV and the Cash You Need

For an HDB resale flat, cash over valuation (COV) is the amount by which the agreed price exceeds HDB’s value. If you agree to S$640,000 and the value is S$600,000, the S$40,000 COV must be paid in cash. CPF savings and the housing loan cannot cover it. CPF Board’s explanation.

Quick answer

COV = the higher of zero and agreed price − HDB value. It is only part of the cash needed. Add any mandatory cash downpayment, CPF shortfall and transaction bills, then keep renovation money and an emergency reserve available. Credit deposits already paid against the purchase price instead of adding them twice.

Price comes before the Request for Value

  1. Obtain a valid HFE letter and set a purchase budget.
  2. Agree the resale price and obtain the seller’s OTP.
  3. If using CPF or a housing loan, submit the Request for Value by the next working day after the Option Date. The fee is S$120 including GST.
  4. Wait for the outcome before exercising the OTP. HDB says it is typically available within 10 working days; the option period is 21 calendar days.

The value outcome is valid for three months from availability; both parties must submit their resale application within that period. A purchase financed entirely with cash, without CPF or a housing loan, does not require this request. HDB’s Request for Value rules.

An agent’s estimate or a nearby transaction is useful context, but does not settle your flat’s value. Before paying the option fee, decide how much cash you can commit if the value comes back below the agreed price. Check the actual OTP deadline and lender requirements rather than counting on an extension.

Worked example: a S$640,000 resale purchase

Assume a Singapore citizen buying a first residential property, no ABSD, a S$600,000 value, and a bank loan at the full 75% LTV limit with a 5% minimum cash requirement. Assume S$120,000 of usable CPF funds and no grants. These are illustrative inputs, not a quotation or assurance of loan eligibility.

The purchase-only cash requirement is S$70,000 under these assumptions
Purchase fundingAmount
Bank loan: 75% × S$600,000S$450,000
Usable CPF for purchase: 20% × S$600,000S$120,000
Minimum cash on the valuation-supported portion: 5% × S$600,000S$30,000
COV: S$640,000 − S$600,000S$40,000
Total purchase price fundedS$640,000

The 75% financing case and 5% cash split follow HDB’s resale financing illustration. Your loan may be smaller because of income, debt, age, tenure, lease or lender conditions. Less usable CPF increases the cash needed; a larger CPF balance cannot pay the COV or replace the mandatory bank-loan cash portion.

Then add the other cash commitments

A funding plan including a retained reserve, not a claim that every item is a purchase fee
Cash allocationIllustrative amount
Purchase cash, including the S$40,000 COVS$70,000
Buyer’s Stamp Duty, assumed paid in cashS$13,800
Request for Value feeS$120
Legal and other transaction costs, assumed budget excluding the valuation feeS$3,000
Renovation and moving, assumed budgetS$40,000
Emergency reserve retained, not spent on purchaseS$30,000
Cash to have available before these paymentsS$156,920

Residential BSD on S$640,000 is S$1,800 + S$3,600 + S$8,400 = S$13,800. IRAS charges BSD on the higher of purchase price and market value, so do not calculate it on S$600,000 merely because that is the financing value. IRAS’s BSD basis and rates. Check ABSD separately for your buyer profile.

If S$5,000 of purchase deposits has already been paid, it forms part of the S$70,000 purchase cash in this example. The remaining purchase cash is S$65,000, and the remaining amount to fund or retain across this whole plan is S$151,920. Ask your solicitor to reconcile the deposit credit and payment dates in the actual completion statement.

How a lower value changes the cash floor

Hold the agreed price at S$640,000. Assume a full 75% bank loan on each value, 5% minimum cash, and enough usable CPF to cover the other 20%. The table excludes duties, fees and reserves.

Cash floor = COV + 5% of the lower price/value, with the stated loan and CPF assumptions
HDB valueCOVMinimum purchase cash
S$640,000S$0S$32,000
S$620,000S$20,000S$51,000
S$600,000S$40,000S$70,000
S$580,000S$60,000S$89,000

The loan also falls as the value falls. A zero-COV transaction can still need cash because of the downpayment, insufficient CPF or other bills. If you have only S$100,000 usable CPF in the S$600,000-value example, purchase cash rises from S$70,000 to S$90,000 at the same S$450,000 loan.

What changes with an HDB loan?

The bank-loan 5% minimum cash rule does not carry over to an HDB loan. Eligible CPF can cover the valuation-supported initial payment, subject to available savings and usage rules. COV still requires cash. The final HDB loan also depends on the actual financing plan; do not assume the largest LTV percentage will always be disbursed.

Compare HDB versus bank loans, LTV limits and the full upfront cash checklist. This article focuses on HDB resale COV; use the valuation guide for a private-property loan’s valuation shortfall.

Set a cash limit before paying for the option

  1. Ring-fence the reserve. Decide which money must remain accessible after completion.
  2. Obtain a realistic loan and CPF estimate. Separate the approved amounts from maximum-rule calculations.
  3. Stress a lower value. Test whether the extra cash still leaves room for duties, moving and necessary repairs.
  4. Compare the premium with another workable home. A shorter commute or suitable layout may matter, but does not guarantee recovery of the premium at resale.
  5. Use the option period to decide. Read the actual valuation and loan offer before exercising.

If the cash gap is too large, do not exercise merely because you have already paid an option fee. A lapsed OTP may cost that fee; exercising creates a binding purchase contract with more serious consequences if completion fails. Review the OTP process and get your solicitor’s advice for the actual contract.

Use valuation versus asking price to assess the price, then the affordability calculator to test ongoing payments. Passing the cash test does not establish that the total purchase is affordable.

Frequently asked questions

Can CPF savings or a housing loan pay the COV?

No. The amount above HDB’s value must be paid in cash.

Is COV the same as the whole downpayment?

No. It is the price above valuation. Other purchase cash can include a mandatory bank-loan cash portion and any CPF or loan shortfall.

Does zero COV mean I need no cash?

No. The loan structure, usable CPF, transaction bills and retained reserve still determine your cash requirement.

Should I add the option deposit on top of the purchase cash again?

No. Deposits credited against the price are part of the purchase funding. Reconcile the amount already paid with the actual completion statement.
