Why this could be an opportunity

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

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.

Price sensitivity

The same scorer re-run at hypothetical asking prices, holding rent, comps and listing history constant. Not a prediction of what the seller would accept.

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 0.83 - below the usual 1.25 test. These are your assumptions, not evidence: only the pre-filled rent and price come from the record.

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.
