Why Your Survey and Your Valuation Give You Different Answers
What the valuation figure means — and why it is not simply your purchase price minus the cost of repairs.
When you receive a survey and a valuation together, it is natural to look at the list of defects and wonder whether the two figures are connected. A common expectation is that each defect found will have been costed and deducted from the value. This guide explains why that is not how valuation works.
What Does the Valuation Figure Actually Mean?
The valuation figure is our professional opinion of what your property would sell for on the open market on the date of inspection, in the condition it was in at that time. It is based on the RICS definition of Market Value:
"The estimated amount for which an asset or liability should exchange on the valuation date between a willing buyer and a willing seller in an arm's length transaction, after proper marketing and where the parties had each acted knowledgeably, prudently and without compulsion."
In plain terms: it is the price a realistic, informed buyer would pay — not a hypothetical perfect figure with costs taken off.
Why Don't You Just Deduct the Cost of Repairs?
This is the most common question we receive, and it is a fair one. The short answer is that deducting repair costs is not how buyers actually price property, and therefore it is not how Market Value is assessed under RICS standards.
When someone views a property, they do not produce a schedule of works and subtract it from a theoretical perfect price. They look at the property as a whole — its location, size, condition, presentation, the local market — and decide what they are willing to pay.
Our valuation reflects that reality. We look at what comparable properties have actually sold for in the local market, in similar conditions, and use that evidence to form our opinion of value. The market's response to condition — including defects — is already embedded in those prices.
So Does Condition Not Matter?
Condition absolutely matters — but it matters in the way the market reflects it.
If the property is in significantly worse condition than comparable properties that have sold nearby, that will weigh on our opinion of value. If it is broadly in line with what the market expects for a property of this age, type and price range, it may have little or no effect on the figure.
What we do not do is take a notional ideal value and subtract line-item repair costs from it. That approach would not produce a Market Value — it would produce something closer to a development appraisal, which is a fundamentally different exercise.
"The assessment of value is not undertaken on a defect-by-defect or cost-of-repair basis. Instead, the property is considered in its overall condition and compared with evidence of similar properties which have transacted in the market in a comparable state."
What Is the Survey For, Then?
The survey and the valuation are two separate professional exercises, provided together for your convenience. They serve different purposes:
The Survey
Tells you about the condition of the property — what defects exist, how serious they are, and what action may be required.
The Valuation
Tells you what the market says the property is worth in that condition, based on comparable evidence.
Together, they give you a complete picture to support your purchasing decision. The survey helps you understand what you are buying. The valuation helps you understand whether the price you are paying is reasonable.
Neither document tells you what you should do. That decision — whether to proceed, renegotiate, or withdraw — is yours to make, informed by both reports and with the support of your solicitor.
