Why Valuation Matters to the Transaction
Property valuation affects three critical elements of every transaction:
- Loan quantum: Banks lend based on the lower of purchase price or market valuation. If the valuation comes in below the agreed purchase price, the maximum loan is calculated on the valuation figure — reducing the loan and increasing the cash the buyer must contribute.
- Stamp duty: Both BSD and ABSD are computed on the higher of the purchase price or market value. If a property transacts above its market value, stamp duty is still computed on the higher figure.
- CPF usage: CPF OA can be used up to the lower of the purchase price or valuation (combined with the loan). Where valuation is below price, CPF usage is capped at the valuation limit, forcing additional cash outlay.
For agents, the practical implication is that any offer price above likely valuation creates a cash requirement that the client may not have budgeted for. Surfacing this risk before the OTP is signed protects both client and transaction.
HDB Resale Flat Valuation
For HDB resale transactions, the valuation is conducted by HDB-appointed valuers engaged by the seller or buyer through the HDB Resale Portal. The valuation is commissioned after the OTP has been granted and before the resale application is submitted.
The HDB valuation determines:
- The Cash-Over-Valuation (COV) amount: COV = purchase price − HDB valuation. COV must be paid entirely in cash — it cannot be funded by CPF or the HDB loan. If the flat is priced at SGD 650,000 and HDB values it at SGD 620,000, the SGD 30,000 COV is a mandatory cash payment on top of the down payment.
- The loan quantum ceiling: The HDB concessionary loan is capped at 80% of the lower of purchase price or valuation. For a SGD 650,000 purchase priced at SGD 620,000 valuation, the maximum HDB loan is SGD 496,000 (80% of SGD 620,000) — not SGD 520,000.
- CPF usage limit: The buyer can use CPF OA funds for the purchase only up to the valuation amount (not the purchase price). If the buyer has SGD 100,000 in CPF OA, they cannot use all of it toward COV.
Agent note: In a competitive resale market, sellers receive multiple offers above valuation. Buyers who commit to a price without understanding the COV implication may find the cash requirement significantly higher than planned. Before advising a buyer to offer above the likely valuation range, model the full cash outlay: down payment + COV + BSD + any ABSD + legal fees + renovation. This prevents the situation where a client’s offer is accepted but financing falls through due to insufficient cash.
Private Property Valuation
For private residential property (condominiums, landed, apartments), valuation is conducted by licensed valuers from the lending bank’s panel. The buyer’s appointed bank will instruct a valuer from its approved panel to assess the property before issuing the Letter of Offer.
Private property valuation considerations:
- Valuation timing: The bank instructes a valuer after the OTP has been exercised and the buyer has applied for the mortgage. If valuation comes in below the purchase price at this stage, the buyer has already committed to the transaction and must either fund the shortfall in cash, renegotiate with the seller, or walk away (forfeiting the OTP deposit, typically 1% of the purchase price).
- LTV impact: The maximum LTV for a first residential property bank loan is 75% of the lower of purchase price or valuation. If a buyer purchases at SGD 1.5 million and valuation is SGD 1.4 million, the maximum loan is SGD 1.05 million (75% of SGD 1.4 million), not SGD 1.125 million. The buyer must fund the SGD 75,000 shortfall in cash above the planned down payment.
- Stamp duty on higher of price or valuation: If the agreed transaction price is SGD 1.5 million and the valuation is SGD 1.4 million, BSD is computed on SGD 1.5 million (the higher figure). The buyer cannot reduce their stamp duty by referencing a lower valuation.
How Valuers Determine Market Value
Licensed valuers in Singapore use the comparison method as the primary approach for residential property valuation. The comparison method assesses recent transacted prices of comparable properties (similar size, floor level, facing, tenure, and location) and adjusts for differences to derive the subject property’s market value.
Key factors that affect valuation:
- Recent comparable transactions: Valuers rely on caveats lodged with URA (for private property) and HDB Resale Portal data (for HDB flats). Caveats reflect actual transaction prices, not listing prices. In a rapidly rising market, recent caveats may not fully capture the current bid environment, leading to valuations below what sellers are achieving.
- Floor level and facing: Higher floors and favourable facings (unobstructed views, no west sun) command premiums. Valuers adjust for these differentials based on comparable data.
- Condition and renovation: For HDB flats, substantial renovation does not typically add proportionally to valuation — valuers assess the flat’s structural value, not the owner’s renovation spend. A premium-renovated flat may still value at market rate for its floor level and facing.
- Remaining lease: Shorter remaining lease on HDB flats is a negative valuation factor. Valuers apply lease-decay adjustments, and older flats in the same block will value lower than younger ones.
Valuation Shortfall Scenarios: What Happens When Valuation Is Below Price
When bank or HDB valuation comes in below the agreed purchase price, the buyer faces a cash shortfall. The agent needs to help the client understand the options:
| Option | Applicable For | Implication |
|---|---|---|
| Fund the shortfall in cash | Buyer has sufficient cash reserves | Transaction proceeds as agreed. Buyer pays the valuation gap in cash on top of the standard down payment. |
| Renegotiate the price with the seller | Seller is open to negotiation; market conditions allow | Purchase price is reduced to match or approach valuation. Requires seller agreement — not always achievable in a seller’s market. |
| Seek a second valuation | Private property; buyer engages own valuer | A second opinion valuation may come in higher. Not always accepted by the bank — the bank’s panel valuer’s figure typically governs the loan. |
| Walk away from the transaction | Buyer cannot fund shortfall | For private property: buyer forfeits the OTP exercise deposit (typically 4%–5% of purchase price). For HDB resale: the OTP deposit (up to SGD 5,000) may be forfeited depending on the stage of the transaction. |
Agent note: In competitive private property markets, buyers who stretch on price to beat competing offers face the highest valuation shortfall risk. The single most useful pre-offer check is to review recent URA caveats for comparable units in the same project and floor band, and form a view on where valuation is likely to land. If the offer price is materially above recent caveats, the buyer needs to be prepared to fund the gap in cash. Agents who raise this proactively position themselves as advisers who protect the client’s interests.
Stamp Duty: Always on the Higher of Price or Valuation
A common client misconception is that stamp duty is based only on the agreed transaction price. This is true when price equals or exceeds valuation — which is almost always the case in arm’s length transactions. But the rule exists in the other direction too: if a transaction is structured at below-market value (e.g., sale to a related party), IRAS will assess BSD and ABSD on the market value, not the lower transaction price.
For standard market transactions, the practical rule is:
- Purchase price ≥ valuation: stamp duty on purchase price
- Purchase price < valuation (e.g., distressed sale below market): stamp duty on valuation
Agents should note that under-the-market transactions between related parties attract IRAS scrutiny on stamp duty, even if the parties have legitimate reasons for the lower price. Always advise clients to seek legal and tax advice before structuring below-market transactions.
Using LEVR to Model Valuation Scenarios
LEVR’s Home Loan Calculator can be used to stress-test the financing impact of a valuation shortfall before the client commits to an offer price:
- Base case: Enter the target offer price as both the purchase price and valuation. This gives the financing model at full price = full valuation.
- Shortfall scenario: Enter the expected valuation (based on recent caveats) as the loan base, and the offer price as the total purchase price. The difference between the two is the cash shortfall the buyer must fund above the down payment.
- Check total cash requirement: Add down payment + valuation shortfall + stamp duty (from the stamp duty calculator) + legal fees to get the total upfront cash required. Confirm the client can fund this before the offer is made.
This three-step check takes under five minutes in LEVR and prevents the most common transaction failure mode: a client who wins the OTP but cannot close because the financing falls short of what was planned.
