How to Learn Property Valuation Quickly and Correctly

A property’s selling price and its valuation are two different numbers. The price is what a buyer and seller agree to pay; the valuation is a professional or institutionally accepted estimate used for financing or other purposes. When the agreed price is higher than the value accepted for a mortgage, a buyer may need more cash and cannot simply ask the bank to finance the difference. This eduKateSG Quick Notes lesson shows how to compare prices and valuations, when an HDB resale buyer requests the flat’s value, and why a careful buyer plans the cash gap before committing.

Price is not value: the agreed sale price is separate from the value used in lending.
Follow the lower number: mortgage and CPF calculations often refer to the lower of the purchase price and accepted valuation.
Learn COV: cash-over-valuation is the amount by which the purchase price exceeds that value.
Know HDB’s process: qualifying resale buyers request a flat’s value after receiving an Option to Purchase.
Check deadlines: HDB’s Request for Value and its validity period have specific timing rules.
Plan all funding: calculate the loan, mandatory cash, eligible CPF OA and additional taxes or fees separately.

Teaching paragraph 1 — understand the two numbers on a resale transaction. Suppose a seller asks S$750,000 for a flat and a buyer agrees, but the relevant accepted valuation is S$700,000. The buyer’s agreed purchase price remains S$750,000. The valuation is not a command for the seller to lower the price, nor is the asking price proof that the flat is worth that much for financing. The S$50,000 difference is called cash over valuation, or COV. In the ordinary Singapore resale context, this amount above the valuation cannot be funded using the housing loan or CPF OA savings. Learn to write price − valuation = COV when price is higher.

Teaching paragraph 2 — calculate what the mortgage can actually cover. Continue with the fictional S$750,000 agreed price and S$700,000 valuation. Assume the buyer meets the conditions for a 75% bank housing-loan ceiling and the bank approves the full illustrative amount against the relevant value. The maximum model loan is S$700,000 × 75% = S$525,000. The uncovered purchase price is S$750,000 − S$525,000 = S$225,000. This is not all necessarily cash, but it includes S$50,000 COV that must be paid in cash. In a standard first-bank-loan example with 5% minimum cash on the lower value, an additional S$35,000 cash requirement produces at least S$85,000 cash in this simplified setup, and the remaining S$140,000 can be met with eligible CPF OA and/or further cash. All other transaction costs are separate.

Teaching paragraph 3 — learn Singapore’s real value-request procedure. For an HDB resale flat financed using CPF savings or an HDB or bank housing loan, the buyer ordinarily submits a Request for Value after receiving an Option to Purchase from the seller. HDB’s 2026 resale terms say the request should be submitted by the next working day after the option date, unless the applicable rules provide otherwise. HDB decides whether a professional valuation is required and, where relevant, assigns its valuer. HDB’s published terms state the determined value is valid for three months for the related transaction. This process provides the value used for financing and CPF planning; it is not approval of the whole resale purchase.

The Three Numbers to Put on Your Page

Do not replace the third number with a headline maximum LTV. A buyer may qualify for less borrowing because of affordability checks, existing housing loans, loan tenure or a property-specific condition. Three different figures can therefore govern one transaction.

If the purchase price is lower than the valuation, financing calculations can still use the lower agreed price. If the price is higher, the difference above valuation generally cannot be covered by CPF OA or the property mortgage. These are two different situations; do not assume the higher number is the loan’s denominator.

Agreed purchase price: the price in the buyer–seller transaction.
Accepted valuation: the value used by the relevant lender or HDB for financing.
Actual approved mortgage: the specific sum a financial institution or HDB has agreed to lend after assessment.

Worked Example: From Price to Cash Requirement

Imagine a buyer pays S$750,000 for a flat valued at S$700,000. The valuation gap is S$50,000. A hypothetical 75% mortgage ceiling applied to S$700,000 produces S$525,000. Thus the entire price gap not covered by this loan is S$225,000.

Under a standard qualifying first-bank-loan 75% LTV scenario, at least 5% of the lower price or value generally needs to be funded with cash. Five per cent of S$700,000 is S$35,000. Add the S$50,000 above valuation, which is separately cash: the illustrated minimum cash need is S$85,000 before stamp duty, legal bills and other charges. The remaining S$140,000 of this price gap may be funded from eligible CPF OA savings and/or cash, subject to limits.

Change the assumed valuation to S$750,000 with the same agreed price, and there is no cash-over-valuation. The 75% ceiling would be S$562,500, and the price gap S$187,500 before other costs. The difference between these examples illustrates how a valuation affects financing even when the seller’s agreed price does not change. Neither calculation is a promise that the bank will approve the ceiling.

HDB Request for Value: When to Apply

HDB’s Request for Value terms explain the submission sequence, while the official questions and answers explain who can apply and where the status is shown. Do not submit a value request simply because you are browsing listings; the stated process is linked to receiving the seller’s OTP.

HDB’s fee and submission requirements can change; check the current HDB Flat Portal when acting. The Request for Value is not a substitute for a valid HFE letter, financing approval or the rest of the resale application.

After OTP: an HDB resale buyer generally obtains an Option to Purchase before submitting the Request for Value.
By the next working day: HDB’s 2026 terms specify submission by the next working day after the option date.
Through approved channels: the buyer can use the HDB Flat Portal or a property agent may use supported services.
HDB decides: HDB determines whether a valuation inspection is needed and appoints the valuer if necessary.
Check the portal: the buyer follows the result and validity information through the official HDB system.

Why Valuation Is Not the Same as Asking Price

The asking price is chosen by the seller. It may reflect negotiating strategy, property condition, location, scarcity and the seller’s expectations. A valuation is an assessment made under a recognised method, usually informed by comparable transactions and property-specific considerations. A registered valuer may consider floor area, location, age, lease, condition and market evidence relevant to the assignment.

Two similar flats can transact at different prices because buyers’ circumstances or timing differ. A property can also be sold above or below its assessed value. Therefore, a published past transaction is useful market context, but it is not the official valuation of the particular property being purchased.

HDB explains in its resale-price FAQ that a Request for Value is intended to support CPF and loan reference values rather than price negotiation or marketing. Buyers and sellers can separately look at recent transacted prices when deciding an offer.

What Happens If the Valuation Comes Back Lower?

First calculate the difference between the agreed purchase price and the value used for the mortgage. Next check whether the lender still permits the planned loan amount under the relevant loan-to-value category. Then recalculate how much must come from cash and eligible CPF OA. Add stamp duty, legal costs and all other transaction expenses to find the full budget requirement.

Do not assume that a lower valuation automatically gives you a contractual right to change the purchase price or cancel a binding agreement. The consequences depend on the particular contract and applicable rules. A person planning a major transaction should consider professional advice before exercising an option without sufficient verified financing.

A Value Can Have a Validity Period

Under HDB’s current resale terms, the value determined through the Request for Value remains valid for three months from the day it is made available in the HDB Flat Portal. If the relevant resale application is not made within the period, a new value request can be necessary and may yield a different value used for CPF and loan planning.

This is one reason not to mix an old valuation with a new home loan application without checking the dates. The market can change, and the lender can assess the transaction using the applicable current evidence. Keep the OTP, value response, lender offer and supporting documents together.

Bank Valuation Versus HDB Resale Value

For private properties, or certain bank-financed transactions, a bank may obtain its own approved valuation and apply its underwriting criteria. In HDB resale transactions, the Request for Value provides a reference for CPF usage and housing finance under the stated conditions; the financial institution may also have specific requirements. You should confirm which value your particular lender will use.

Do not assume that an agent’s market appraisal, a bank’s desktop estimate and a formal valuation for mortgage purposes are identical. The relevant official documents and their permitted uses determine whether the figure is suitable for financing.

Check Your Understanding

Question 1: A flat costs S$750,000 and is valued at S$700,000. What is COV? Answer: S$50,000.

Question 2: What is 75% of a S$700,000 valuation? Answer: S$525,000.

Question 3: Can a bank necessarily use the higher agreed sale price as the basis for maximum financing? Answer: No. The relevant lower value and bank assessment can matter.

Question 4: Does the HDB Request for Value itself approve the entire resale purchase? Answer: No.

Question 5: Is COV ordinarily payable using CPF OA? Answer: No; the amount above accepted valuation must be cash.

Common Mistakes to Avoid

Calling an asking price a formal valuation.
Assuming the advertised selling price controls every loan-to-value calculation.
Leaving cash-over-valuation out of the cash budget.
Counting CPF OA savings as available to pay COV.
Requesting HDB’s official value before the required transaction stage.
Ignoring the next-working-day and three-month rules in HDB’s process.
Treating a value determination as final mortgage approval.

Official Sources and Final Rule

Official references: HDB — Resale Flat Terms, HDB — Request for Value, MoneySense — Property Affordability, and CPF Board — Downpayment and Valuation. These are educational examples and the dates and requirements should be checked before any real transaction. Final rule: compare the agreed price with the accepted value, then budget the financing and cash separately.
