A desktop property valuation is prepared without a new physical inspection, using information and market evidence available to the valuer. It can be proportionate for some clearly defined instructions, particularly an update to a recent inspected valuation, but it is not a cheaper substitute that is automatically suitable for every property or purpose.
The valuer must understand why the figure is required, who will use it, the relevant valuation date and whether reliable information is available. If the property has changed, evidence is weak or the recipient requires an inspection, a desktop approach may be inappropriate.
What information replaces the visit
The valuer may consider a recent inspection record, floor plans, photographs, title or lease information, sales particulars, previous reports and verified comparable transactions. They also need confirmation of changes in condition, occupation, alterations and material legal circumstances since any earlier inspection.
Information supplied by the client is not accepted blindly. Its source, reliability and relevance should be considered, and important assumptions or uncertainty must be communicated.
When it may be proportionate
An update shortly after a full inspection may be suitable where the same valuer understands the property and nothing material has changed. Homes England, for example, publishes a specific desktop route for extending an expired Help to Buy report when detailed conditions are met.
Other possible uses depend entirely on the recipient and agreed purpose. A client should never assume that a court, lender, housing provider or tax authority accepts desktop evidence.
When an inspection is preferable
A visit may be necessary where condition is material, substantial works have taken place, the property is unusual, records conflict or the last inspection is no longer a reliable description. An inspection can also be required expressly by the recipient’s rules.
A desktop valuation is not a home survey. It offers no current inspection of defects and should not be used by a buyer seeking condition and repair advice.
Terms and report limitations
The terms should state that no physical inspection is being undertaken, describe the information relied upon and explain the resulting assumptions and limitations. The report remains tied to its specified property interest, users, purpose and valuation date.
A desktop opinion does not guarantee a sale price or third-party acceptance. If new information becomes available, the valuer may need to reconsider the conclusion.
A desktop valuation is also different from an automated estimate. A professional report still requires a defined instruction, appropriate investigations, judgement and accountability. The absence of a visit does not remove the need to analyse comparables or explain uncertainty; it makes the quality and completeness of documentary evidence more important.
- Confirm that the recipient permits a desktop approach
- Supply reliable plans, photographs and property documents
- Disclose every material change since any earlier visit
- Understand that no current condition survey is provided
