Which pricing assumptions need checking?
A captured residential estimate with a wide range and an unresolved floor-area assumption.
Editorial interpretation of production responses captured on 6 September 2026. This is not a newly run workflow or a customer case study.
The decision to investigate
What further evidence would be needed before progressing at a proposed price?
What the captured evidence shows
The captured response gives an indicative value of £440,830 and a range of £227,909–£668,415. It flags floor area as copied from the building rather than directly observed. The proximal evidence contains two sales for one unit, carried to December 2025.
Proposed next investigation
Verify the unit and its floor area, inspect the comparable sales and obtain evidence of condition before using this estimate to assess a proposed price.
Limits of this example
This is an automated estimate, not a professional valuation. Its confidence score is not demonstrated accuracy. The captured model version is gbm-h3-v3.2; no customer action or accuracy improvement has been measured here.
Cost and reproducibility
Each capture below shows the request, date and recorded charge when available. These excerpts do not measure an end-to-end workflow cost or research time. Supporting address, property, comparable and ownership calls may add charges; an unknown charge is not zero.
Responses are trimmed historical records. Source observation dates differ from capture dates. Product version is only known where recorded in the response. Re-run and review the complete result before relying on it.
