Almost every buyer treats the bank valuation as a black box, a number that appears somewhere between exercising the option and getting the loan approved, with little visibility into how it was reached. That opacity is a large part of why a low valuation feels like a punch out of nowhere. It rarely is. There is a defined process behind that number, and understanding it changes how you approach the whole financing timeline. This guide covers the mechanics themselves. If a valuation has already come in below your purchase price, my separate guide on what to do next walks through your options in that specific situation.

What a panel valuer actually is

A panel valuer is a professional valuer or valuation firm that a bank has vetted and approved to sit on its list, or panel, of valuers it uses for mortgage related assessments. Banks do not let borrowers choose who values their property, and this is deliberate. The valuation exists primarily to protect the bank's own lending decision, ensuring the loan quantum is grounded in an independent, professionally supported figure rather than the purchase price alone. Once your mortgage application reaches the stage where a valuation is needed, the bank assigns a valuer from its panel, and that valuer conducts the assessment on the bank's instruction.

The comparison method, in practice

For the vast majority of residential property, HDB flats and private condos alike, valuers rely primarily on the comparison approach. This means looking at recent transacted prices of similar units in the same or a comparable development or area, then adjusting for the specific attributes of the unit being valued, floor level, stack, size, orientation, condition, and any renovation or defects that would affect value. The goal is not to guess at what the unit should be worth in the abstract, but to anchor the figure in what buyers have actually paid for genuinely comparable units recently.

This is why valuation tends to lag rather than lead a fast moving market. If prices are climbing quickly, the most recent comparable transactions the valuer can reasonably rely on may already be a few weeks or months old, which can create a gap between what a highly motivated buyer is willing to pay today and what the comparison method supports. The reverse is also true in a cooling market, where valuations can sometimes lag on the way down as well.

Why two banks can value the same unit differently

This is the question I get asked most often, usually by a buyer who has just seen two valuations land on different numbers and is trying to work out which one is right. The honest answer is that both can be reasonable, because valuation is not a purely mechanical calculation. Different banks use different panel valuers, and each valuer applies professional judgement in ways that can genuinely diverge: which comparable transactions to weight most heavily, how recent a transaction needs to be to count as relevant, and how much adjustment to apply for differences in floor level or condition. Small differences in these judgement calls compound into a different final figure, even when two valuers are drawing from broadly the same pool of nearby transactions.

Why the valuer's independence matters to you as a buyer

It is tempting to see the valuer as an obstacle standing between you and your loan quantum, but the independence of the process is actually a protection, for the bank and, indirectly, for you. A valuation that simply rubber stamped whatever price a buyer and seller agreed on would defeat its own purpose, and would expose both the bank and the borrower to lending decisions untethered from real comparable value. Understanding this reframes a valuation that comes in below your purchase price: it is not the valuer being difficult, it is the valuer doing the job the bank assigned them to do, applying the comparison method honestly to the evidence available.

How to request a second valuation

If a valuation comes in below your purchase price and you believe it does not reflect genuinely comparable recent transactions, you have two practical paths. You can ask your existing bank whether a different panel valuer can be assigned to review the property, since a different valuer applying the same comparison method might reach a different figure, particularly if new comparable transactions have completed since the first valuation. Alternatively, you can approach a different bank altogether, since each bank's panel is not identical and a different institution's valuer may reach a different conclusion. Either route usually involves a fee for the additional valuation, so it is worth weighing that cost against how material the shortfall is to your actual financing before committing to a second opinion.

How to think about valuation before you even make an offer

1. Do your own comparable check before committing to a price. Recent transactions in the development or immediate area give you a rough sense of where a valuer is likely to land.
2. Understand that valuation and asking price are different questions. A seller's asking price reflects what they want; a valuer's figure reflects what recent transactions support.
3. Budget for a possible gap. If you are buying in a fast rising segment, build in the possibility that the valuation lags your purchase price, and know your fallback, extra cash, CPF, or renegotiation, before you exercise the option.

Frequently asked questions

What is a panel valuer?

A panel valuer is a professional property valuer or valuation firm that a bank has approved and appointed to its list, or panel, of valuers it uses to assess property value for mortgage purposes. Banks maintain these panels so that every valuation feeding into a loan decision comes from a firm the bank trusts to apply consistent, independent methodology, rather than allowing a borrower to choose any valuer they like.

How do panel valuers decide what a property is worth?

The dominant method for residential property is the comparison approach, where the valuer looks at recent transacted prices of similar units nearby, adjusting for differences in floor level, size, condition, orientation, and other factors, to arrive at a supported value. Valuers may also consider the property's own transaction history and general market conditions, but comparable transactions carry the most weight for a standard home or condo valuation.

Why can two banks value the same property differently?

Two banks often use different panel valuers, and each valuer applies professional judgement, which comparable transactions they weight most heavily, how they adjust for a unit's specific attributes, and how recent a comparable needs to be to count. Small differences in judgement can produce a different final figure even when two valuers are looking at broadly the same set of nearby transactions. This is a normal feature of the process rather than a sign that one valuation is wrong.

Can I request a second valuation if I disagree with the first?

Yes, this is a common and reasonable step. If a valuation comes in below the purchase price, you can ask your bank whether a different panel valuer can review the property, or you can approach a different bank altogether, since each bank's panel and process can produce a different outcome. There is usually a cost involved in commissioning an additional valuation, so it is worth weighing that cost against how material the valuation gap is to your financing.

Does the buyer or seller choose the valuer?

Neither, in the sense of hand picking an individual. The bank assigns a valuer from its approved panel once a mortgage application triggers the need for a valuation. This is deliberate, since the valuation exists to protect the bank's lending decision, and allowing a borrower or seller to select the valuer would undermine the independence the process is designed to preserve.
