The starting point

Read the purpose, property interest, date, assumptions and limitations alongside the conclusion. Check what was inspected and what evidence supports the opinion before using the figure for a decision.

Read the instruction first

It is natural to turn straight to the conclusion. Before relying on it, read what the valuer was asked to do. A report prepared for one client and purpose may not be suitable for another reader, another date, or another property interest.

Look for the intended use, the valuation date, the interest assessed, and the basis of value. Check whether the property was inspected and whether any parts were inaccessible. These matters are also addressed in the RICS Global Standards on valuation instructions and reports (RICS, 2024). They tell you how the opinion should be read. They are part of the substance, not small print added afterwards.

Follow the route from evidence to opinion

A good explanation lets the reader understand why particular evidence was selected. The Royal Institution of Chartered Surveyors (RICS) comparable-evidence standard addresses the availability, sources, and assessment of that evidence (RICS, 2023). In practice, ask which transactions carried most weight and what made them relevant.

The method should suit the asset and the instruction. An owner-occupied house, an income-producing building, and a development site can raise different questions. A report should explain its approach in terms the intended reader can follow, without relying on technical language to carry an argument it has not made.

Take assumptions seriously

An assumption is something accepted as true for the valuation without separate verification, where that is reasonable for the purpose (RICS, 2024). A report may, for example, rely on title information supplied by a solicitor or building information supplied by an engineer. Check what has been verified, what is assumed and what remains outstanding.

A special assumption may describe circumstances different from those actually existing at the valuation date, and needs clear agreement and labelling (RICS, 2024). The value of a completed development is not necessarily the value of the property as it stands. Nor should an assumption of vacant possession disappear into a report where somebody remains in occupation.

A valuation inspection should not be mistaken for a comprehensive building survey. The Competition and Consumer Protection Commission (CCPC) discusses a structural survey separately from mortgage valuation requirements (CCPC, n.d.-b). If condition is important to the decision, agree the appropriate inspection with a qualified specialist.

Ask a precise follow-up question

If something is unclear, identify the point. “Was the rear extension included in the floor area?” is more useful than “Can you make the figure higher?” A question about a missing transaction can be answered by considering that evidence. A request for a preferred result cannot replace professional judgment.

Check the report’s limitations on use and distribution before forwarding it. If the purpose has changed, ask whether a new instruction is required. A well-used valuation is a reasoned piece of advice within an agreed scope. Understanding that scope helps the figure do the job it was prepared to do.
