Why this could be an opportunity

Low confidence0 independent sourcesLead to verifyListing checked 14 Nov 2026

This rests largely on a single source. Treat the score as a prompt to investigate, not a conclusion.

Check before relying on this score: leasehold with no service charge disclosed - the stress test assumes GBP 0. It ranks after every home whose inputs are verified.

4 of 4 components scored. Ranks on gross yield, the stress margin, risk and disclosed facts. A pricing claim earns only its measured edge: today 0 for the market estimate and at most +0.5pp for sold evidence. The score itself is not yet checked against the outcomes of homes it scored.

Risks

What could kill this deal

Score confidence is low
largely a single source - treat the number as a prompt, not a conclusion

Plan

Before you offer

1. Get two written rental appraisals from local lettings agents.
The rent estimate rests on area-level evidence, not lettings on this street.
2. Commission a full structural survey, not a basic condition report.
The score prices market evidence, not the fabric of the building.

Every step above was generated from a specific gap or flag in the evidence - no generic advice, no invented tasks.
