Bank valuation is the lender's security assessment of a property; market value is the likely arm's-length sale price. In Singapore, the loan quantum is sized on the lower of the purchase price or the bank valuation, while stamp duty) can be assessed on the higher of the two. Any gap between valuation and price, known locally as cash over valuation, falls to the buyer to fund in cash.
TL;DR:
- Lenders apply their loan-to-value limits to the lower of the purchase price or the bank valuation, which can result in a cash shortfall if the agreed price exceeds the valuation.
- A valuation lower than the purchase price requires the buyer to fund the difference as cash over valuation and limits the mortgage amount accordingly.
- Stamp duty is calculated on the higher of the market value or the purchase price, which can incur extra costs even if the buyer secures a good deal.
- For HDB resale flats, the Request for Value is valid for a limited period, and delays can lead to additional valuation refreshes and transaction setbacks.
- Buyers should obtain their loan eligibility and run affordability checks before exercising the Option to Purchase to avoid surprise cash obligations.

What 'bank valuation' and 'market value' mean in Singapore
A bank valuation is the figure a lender's panel valuer assigns to a property as security for a loan, dated to a specific valuation date and produced for the bank's own risk assessment rather than for the buyer's benefit, as explained in this building valuation in Singapore guide. Market value, by contrast, is defined by RICS and the International Valuation Standards as the most likely exchange price in an arm's-length transaction between a willing buyer and seller. The two concepts serve different purposes: one protects a lender's downside, the other estimates what the market would actually pay.
In practice, several figures can exist for the same property at the same time:
- Bank-appointed panel valuers, who produce the valuation a mortgage is based on.
- The HDB Request for Value, which applies specifically to resale flats financed with CPF or a housing loan.
- Platform or desktop estimates, such as those available through haio, which draw on transaction data for quick research reference.
- Agent appraisals, which reflect current asking-price sentiment rather than a formal valuation.
Each figure is produced under different instructions and at a different point in the transaction, which is why they rarely match exactly.
How valuations change your mortgage: LTV, cash over valuation and TDSR
Lenders apply their loan-to-value limit to whichever figure is lower: the agreed purchase price or the bank valuation. This is the rule that turns a valuation shortfall into an immediate cash requirement.
- The bank values the flat at a given figure while the agreed price is higher.
- The loan-to-value ratio is applied to the lower figure, not the purchase price.
- The difference between the purchase price and the loan amount, beyond the buyer's own planned down payment, becomes cash over valuation and must be settled in cash.
For example, if a flat is agreed at S$1,000,000 but the bank values it at S$950,000, MAS's lower-of-price-or-valuation framework means a 75% loan-to-value cap applies to S$950,000, producing a loan of S$712,500 rather than S$750,000: a S$37,500 shortfall that typically must be covered in cash since CPF and loan proceeds are both capped against the valuation, not the price.
Even when a valuation fully supports the purchase price, the loan is not guaranteed. The Total Debt Servicing Ratio framework requires lenders to separately test whether a borrower's income can service the proposed loan alongside existing debt obligations, and a loan amount can be reduced even where the valuation is adequate. Lenders may also apply their own floors or conservative haircuts on top of the official limits, further reducing the usable loan amount.
HDB resale flats: Request for Value timing and validity
Buyers of HDB resale flats who intend to use CPF savings or a housing loan must submit a Request for Value to HDB, typically by the next working day after obtaining the Option to Purchase. HDB then assigns a valuer from its own panel: buyers cannot choose or request a particular valuer, which often surprises those expecting to check valuation before committing to a price.
- The resulting HDB value becomes the reference point for CPF usage and, unless the bank advises otherwise, for the housing loan itself.
- The value is valid for a limited period from the date it is issued.
- If the resale application is not lodged within that window, a fresh Request for Value is required, which can delay the transaction and reset the valuation figure.
Pro Tip: Apply for your bank's loan eligibility letter before exercising the Option to Purchase, so you know your borrowing capacity before HDB's Request for Value locks in the reference figure.
What happens when valuation is higher or lower than the agreed price
The direction of the gap between valuation and price determines who carries the financial consequence.
- When the valuation comes in below the agreed price, the buyer funds the cash over valuation amount directly, the loan is sized on the lower valuation figure, and CPF withdrawal is similarly capped against that valuation rather than the price paid.
- When the valuation comes in above the agreed price, the buyer does not receive the difference in cash; the purchase price generally remains the basis for the transaction, though a higher valuation can ease the cash burden since less of the price sits above the financeable base.
- In both cases, the loan amount still depends on passing TDSR and the lender's own credit assessment, so a favourable valuation never substitutes for affordability.
Agents in Singapore often caution buyers against bidding well above the expected valuation range, precisely because the shortfall becomes an immediate cash obligation, rather than something a bank can absorb into the loan.
Tax and stamp duty consequences: why valuation matters beyond the loan
Buyer's Stamp Duty operates on an entirely separate rule from mortgage lending. IRAS charges BSD on whichever is higher: the purchase price or the market value of the property.
- If a flat is bought below market value, stamp duty is still calculated on the higher market value figure, not the discounted price paid.
- If a flat is bought at or above market value, the purchase price itself forms the basis for BSD.
This means a buyer securing a bargain still faces stamp duty calculated on the property's full market value, a cost that must be modelled separately from any mortgage shortfall or cash over valuation, since the two run on parallel tracks with different reference figures.
A practical checklist before exercising the OTP
Before committing to an Option to Purchase, a structured check of financing and valuation exposure avoids last-minute cash surprises.
- Obtain your bank's loan eligibility letter or in-principle approval to confirm indicative borrowing capacity.
- Estimate your likely cash over valuation exposure using recent comparable transactions.
- Confirm your CPF withdrawal limits, which follow the lower of price or valuation, not your intended budget.
- Ask the bank about its panel valuer process, expected timing and whether it applies any internal LTV floor.
- For resale flats, confirm when HDB's Request for Value will be submitted and how that aligns with your Option to Purchase timeline.
- Run your own TDSR stress test assuming a less favourable interest rate.
Pro Tip: Ask your bank directly what loan base it will use if the valuation and purchase price differ, since practices on rounding and floors vary between lenders.
How haio's tools help you anticipate the valuation gap
Instant valuation estimates and affordability checks through haio let buyers approximate likely cash over valuation and CPF impact before committing to an Option to Purchase, using transaction data rather than guesswork.
- Run a quick valuation estimate on a shortlisted flat to gauge how it compares with the asking price.
- Use the affordability tool to model loan quantum, TDSR headroom and likely cash requirements together.
- Treat these estimates as research aids: the bank's panel valuation or HDB's Request for Value remains the figure that governs the actual loan and CPF usage.
A note on risk-aware planning
We'd urge Singapore buyers to treat a high desktop or agent estimate as encouragement, never as confirmed borrowing power. Plan for cash over valuation before you bid, model stamp duty separately from your loan, and cross-check figures against HDB and MAS guidance rather than a single source. A quick check through haio's valuation and affordability tools can sharpen that planning before you commit.

FAQ
What is the difference between a bank valuation and a market value?
A bank valuation is a lender's security assessment, produced by a panel valuer to support a mortgage decision, while market value is the likely arm's-length sale price under RICS and IVS definitions. In Singapore, loans are sized on the lower of the purchase price or the bank valuation, so the two figures carry different financial consequences even when they're close.
What is the difference between valuation and market value?
Valuation generally refers to a formal assessment carried out for a specific purpose, such as lending security, while market value is a broader concept describing the most probable price in an open-market transaction. A bank valuation is one specific application of valuation methodology, produced with the lender's risk rather than the seller's price expectation in mind.
How much less is a bank valuation?
There's no fixed margin: a bank valuation can land above, at, or below the agreed purchase price depending on recent comparable transactions and the valuer's own assessment date. Where it comes in lower, the shortfall becomes cash over valuation, which must be funded in cash since the loan and CPF use are both capped against the lower figure.
What happens if bank valuation is higher than purchase price?
If the bank valuation exceeds the purchase price, the buyer generally doesn't receive the difference in cash, and the purchase price typically remains the practical basis for the transaction. A higher valuation can still ease the cash burden in some calculations, though the loan amount remains subject to TDSR and the lender's own credit assessment regardless of how favourable the valuation looks.
