What Is a Bank Valuation?
When a buyer applies for a bank home loan in Singapore, the lender engages an independent valuer (from a MAS-approved panel) to assess the property's open market value. This valuation — commonly called the bank valuation or indicative valuation — determines the maximum amount the bank will lend.
Bank valuations are based on comparable transacted prices (recent sales of similar properties in the same development or vicinity), not on the agreed purchase price between buyer and seller. This distinction matters because the agreed purchase price may differ from the bank's assessed value.
How Singapore Loan Quantum Is Calculated
Under MAS regulations, a bank's maximum loan quantum is computed as a percentage of the lower of the purchase price or the bank valuation:
- LTV limit: For most buyers (no outstanding home loans), the maximum LTV is 75% of the lower of purchase price or valuation.
- If purchase price = $1,500,000 and bank valuation = $1,500,000 → maximum loan = $1,125,000.
- If purchase price = $1,500,000 but bank valuation = $1,400,000 → maximum loan = 75% × $1,400,000 = $1,050,000. The $100,000 gap must be funded in cash.
Cash Over Valuation (COV)
When the agreed purchase price exceeds the bank valuation, the difference is called Cash Over Valuation (COV). COV is significant because:
- COV must be paid entirely in cash — it cannot be funded by the bank loan or CPF Ordinary Account.
- CPF usage is capped at the bank-valued amount (subject to CPF withdrawal limits and the remaining lease), not the purchase price.
- Stamp duty (BSD and ABSD) is computed on the higher of purchase price or valuation — so COV transactions result in stamp duty on the full purchase price.
| Scenario | Purchase Price | Bank Valuation | COV | Max Loan (75% LTV) |
|---|---|---|---|---|
| At valuation | $1,400,000 | $1,400,000 | Nil | $1,050,000 |
| COV scenario | $1,500,000 | $1,400,000 | $100,000 (cash only) | $1,050,000 |
| Under-valuation (rare) | $1,300,000 | $1,400,000 | Nil (price < val) | $975,000 (75% × $1,300,000 — lower of two) |
CPF Usage and the Valuation Limit
CPF OA funds can be used to fund the property purchase, but only up to the bank valuation (subject to CPF withdrawal limits and remaining lease requirements). The COV portion cannot be paid using CPF — it must come from the buyer's own cash savings.
For a transaction with COV, the buyer's cash requirement is:
- Minimum 5% option exercise cash (non-CPF portion of down payment)
- Plus full COV amount in cash
- Plus stamp duty in cash (BSD and ABSD are computed on purchase price)
- Plus legal fees in cash
The CPF OA balance is applied against the remaining 20% of the bank-valued amount (the down payment portion above the loan), subject to the CPF Valuation Limit.
Why Bank Valuations Differ from Agreed Prices
Several factors cause bank valuations to diverge from purchase prices:
- Market lag: Valuations are based on recent comparable transactions — typically 3–6 months of recent sales data. In fast-rising markets, valuations lag the current market, creating COV.
- Unique property features: High-floor premium, corner unit premium, or renovated condition may be reflected in the purchase price but discounted by valuers who apply comparable-based methodologies.
- Thin comparable sales: For very large or niche units (e.g., a 5,000 sq ft penthouse in a small development), valuers have few comparables and may apply conservative estimates.
- Development stage: For resale properties in new or recently completed developments, limited subsale or resale transactions mean valuers rely on original developer pricing, which may not reflect subsequent price growth.
HDB Resale: No COV Since 2014
Prior to 2014, HDB resale flats were subject to significant COV — buyers paid premium cash sums above HDB's approved value, which drove prices. HDB abolished COV for its resale transactions in 2014 under the resale price negotiation framework.
Today, HDB resale prices are agreed between buyer and seller and registered with HDB. The HDB Loan Eligibility (HLE) letter and bank loan for HDB resale are computed on the basis of the HDB resale approved value, not the COV framework. Buyers using a bank loan for HDB resale should still obtain a bank valuation — the bank may value the flat lower than the transacted price, creating a cash top-up requirement.
When to Get a Valuation
Timing the valuation request matters:
- Before making an offer (indicative valuation): Some banks offer a desktop or indicative valuation before the buyer commits. This is non-binding but gives a rough sense of likely valuation.
- After OTP (formal bank valuation): The formal valuation typically occurs after the OTP is signed and the buyer applies for the bank loan. If the valuation comes in below the purchase price at this stage, the buyer faces the COV cash shortfall — with the OTP already exercised or about to be exercised.
- Agent's role: Agents should advise buyer clients to check bank valuation expectations before exercising the OTP, particularly in fast-moving markets or for transactions significantly above recent comparable prices in the same development.
Frequently Asked Questions
Q: Which bank's valuation counts if I use multiple banks?
A: If a buyer applies to multiple banks, each bank orders its own valuation through its approved panel. The buyer uses whichever bank they proceed with — and that bank's valuation applies. If two banks value the same property differently, the buyer can choose the bank offering the higher valuation (and thus a larger loan), subject to TDSR limits.
Q: Can I negotiate the sale price down if the bank valuation comes in lower?
A: If the OTP has not yet been exercised, the buyer can attempt to renegotiate the price with the seller based on the bank's valuation. Sellers are not legally required to reduce the price, but some will if they want the transaction to proceed. If the OTP has already been exercised, the buyer is contractually bound at the agreed price and must fund the COV in cash.
Q: Does stamp duty use purchase price or bank valuation?
A: BSD and ABSD are computed on the higher of purchase price or bank valuation. In a COV situation (purchase price > valuation), stamp duty is based on the purchase price — the full amount transacted. In the rare case where valuation exceeds purchase price, stamp duty is based on the valuation.
Q: How do I find out the bank valuation before committing?
A: Ask your mortgage broker or bank relationship manager to arrange a desktop (indicative) valuation before you exercise the OTP. Desktop valuations are faster and less expensive than formal on-site valuations, and give a reasonably reliable range. For high-value or unusual properties, consider commissioning a full formal valuation from an independent licensed valuer.
Q: Can COV affect whether I can proceed with the purchase?
A: Yes. If a large COV emerges after OTP exercise and the buyer does not have sufficient cash to cover the gap, they may be unable to complete the purchase. This results in forfeiture of the exercise deposit (typically 4%–9% of purchase price) and potential legal liability. Buyers should always maintain a cash buffer above their estimated minimum cash requirement.
