An advertised price shows what a seller is asking. It does not establish what a buyer paid, whether the asset sold or what the transaction included. Treat it as one piece of evidence with a clearly labelled status.
Before using a listing to challenge an estimate, check whether the equipment and sale circumstances are genuinely comparable. The same model name is only a starting point.
Build a comparable-evidence sheet
| Field | What to record |
|---|---|
| Source and date | Exact page or document and when you checked it |
| Price status | Asking, stated completed sale, reported hammer result or unknown |
| Asset identity | Model, configuration and any relevant differences |
| Condition evidence | What is actually documented or disclosed |
| Included items | Tooling, attachments, services and other additions |
| Location and removal | Where it is and who bears the work or cost |
| Price basis | Fees, taxes and other amounts included or excluded |
| Transaction limits | Reserve, conditions or missing information |
| Relevance to your asset | Similarities, differences and unanswered questions |
Do not label a disappeared advertisement as a completed sale. It may have been withdrawn, moved or changed. If a result is stated, preserve the source and what it actually confirms.
Three evidence labels worth keeping
Confirmed transaction evidence: you have a reliable source establishing the transaction and enough context to understand the reported amount. It may still require adjustment or interpretation by a valuer.
Asking-price evidence: the offer is visible, but the amount achieved is not established. The advertised package may include dealer preparation or services absent from your sale.
Unverified indication: a recollection, unsupported message or unexplained number. It may prompt further research, but it should not carry the same weight as a traceable transaction.
BidSpotter's terminology guide distinguishes hammer price from additional buyer costs. Do not compare one with an all-inclusive dealer price without explanation.
Resist easy arithmetic
A mean of five asking prices is still an average of asking prices. It does not become a sale valuation merely because the calculation is precise. Nor does subtracting an arbitrary percentage create a reliable estimate of the negotiated result.
Use the age-and-usage guide to identify one set of differences, then consider condition and the proposed transaction. The valuation overview explains how that evidence fits into an opinion rather than replacing the valuer's judgment.
Use the sheet to ask better questions
If an actual offer is below expectations, compare its scope with the evidence before rejecting it. The low-offer guide helps structure that discussion. Ask which differences matter and what additional information would improve confidence.
Keep the sources in the valuation evidence file. Web pages can change, so preserve an appropriate dated record through the business's normal document process without treating it as permission to reproduce somebody else's catalogue.
Send UK Auction Group the relevant examples with their limitations. A short, honest comparison is more useful than a folder of expensive listings selected only because they support the preferred number.
