What Is Property Valuation and Who Decides It?

Every property transaction in Singapore involves two separate numbers that buyers often conflate: the purchase price — what you and the seller agree to — and the valuation, an independent professional opinion of the property’s fair market value. They frequently match closely, but they don’t have to, and the gap between them has real financial consequences.

For private resale property, valuation is carried out by a professional valuer drawn from the bank’s approved panel, engaged once you apply for a home loan. For HDB resale flats, valuation is arranged through HDB’s own valuation process after the Option to Purchase (OTP) is exercised. In both cases, valuers assess comparable recent transactions (drawing on data such as URA’s REALIS caveats for private property), the unit’s floor level, orientation, condition, remaining lease, and other value drivers — arriving at an independent figure that neither buyer nor seller controls.

This is distinct from Annual Value (AV), which the Inland Revenue Authority of Singapore (IRAS) uses purely to calculate property tax, and which has no bearing on your loan quantum. Don’t confuse the two when budgeting.

The Golden Rule: Loan and CPF Are Capped at the Lower of Price or Valuation

This is the single most important mechanic to understand. The Monetary Authority of Singapore (MAS) sets Loan-to-Value (LTV) limits that banks must apply — up to 75% for a first housing loan with a tenure of 30 years or less (and where the loan does not extend past the borrower’s age of 65). But that 75% is calculated against the lower of the purchase price or the bank’s/HDB’s valuation — never the price alone.

The same logic applies to CPF usage: you can only draw CPF Ordinary Account savings up to the Valuation Limit, which is anchored to the valuation, not the agreed price. If you have agreed to pay above valuation, that excess sits entirely outside both the loan and CPF systems — it must come from cash savings.

What Is Cash-Over-Valuation (COV)?

Cash-Over-Valuation, universally shortened to COV, is the amount by which your agreed purchase price exceeds the property’s valuation. If you agree to pay S$850,000 for a flat that is subsequently valued at S$830,000, your COV is S$20,000 — an amount you must fund entirely in cash, on top of your normal downpayment.

COV became a well-known (and often painful) feature of the HDB resale market during the property boom of 2011–2012, when median COV amounts on some transactions were widely reported in the tens of thousands of dollars, as buyers competed for flats in a tight, fast-moving market with limited price transparency. HDB responded with a significant reform in March 2014: valuation would no longer be obtained and disclosed before price negotiations, but only after the OTP is signed, removing the anchoring effect that valuation figures had previously had on asking prices. Since then, median COV levels across the HDB resale market have fallen substantially, though COV has not disappeared entirely — it still surfaces for sought-after units in tight micro-markets.

Private Property Valuation: How Bank Valuers Work

For private resale property, the process starts once you sign the OTP and apply for a home loan. The bank engages an independent valuer from its approved panel — not an estate agent, and not a party with any financial interest in the transaction — who conducts a desktop and often a physical inspection of the unit, benchmarking it against recent comparable transactions in URA’s caveat data, adjusting for floor level, stack, renovation condition and view. The valuer submits a report to the bank, typically within a few business days, and the bank bases your maximum loan quantum on that figure.

Because valuers exercise professional judgement, valuations can differ modestly between banks — it is common practice for buyers with a borderline COV situation to apply to more than one bank and compare valuations before committing to a lender.

Why This Matters: What a Big COV Gap Signals

A meaningful COV gap is rarely random — it usually signals that a specific unit is in unusually high demand relative to its comparable transactions: a rare high-floor stack, an unusually large layout for its flat type, or a location experiencing a fast-moving upgrade thesis (proximity to a new MRT line, for example). Buyers should treat a request for a price significantly above asking as a signal to budget conservatively for cash, particularly first-time buyers who may not have deep cash reserves beyond their CPF.

Singapore’s post-2014 valuation-after-OTP framework is, by regional standards, unusually transparent. In markets such as Hong Kong’s private resale sector, informal “over-ask” premiums persist without an equivalent independent bank-valuation checkpoint forcing price discipline, making Singapore’s system comparatively protective of buyers once the mechanics are understood. The trade-off is that Singapore buyers only discover their true financing gap after committing to an OTP — which is precisely why understanding this mechanism before you sign is so important.

What Might Come Next

The following is informed speculation, not confirmed policy. The HDB Resale Price Index has now recorded two consecutive quarters of decline (1Q2026 and 2Q2026), and HDB has already shown a willingness to ease adjacent rules in response — removing the 15-month wait-out period for private property owners on 28 July 2026. If resale price moderation continues, it is plausible that market-wide COV incidence could narrow further as competitive bidding pressure eases, though this is a market outcome rather than a policy lever HDB directly controls. No changes to the post-OTP valuation framework itself have been signalled.
