Opportunity

Why this could be an opportunity

Low confidence0 independent sourcesLead to verifyListing checked 3 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; lead to verify: the advert has 3 bedrooms but the valuation snapshot describes 1 - an extension, conversion or HMO the evidence does not reflect, or a different home. It ranks after every home whose inputs are verified.

Valuation edge-0.6/15
claims [AVM -36.7% (MEDIUM)] → measured edge -0.12pp of the ask; on later-registered sales an AVM discount carried no edge and a sold-evidence gap at most +0.5pp; asking more than 10% above the estimate (measured -0.33pp)

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
Rental economics needs verification before you rely on it
rent estimate 1750/mo (range 1650-1900)
Stress margin needs verification before you rely on it
costs not disclosed by the advert

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.
