Why this could be an opportunity

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

Economics

What happens to your money

Price sensitivity

£319,000£488,500

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.

Score at this price: 20

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 1.32 - clears 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. Treat the gap to the estimate as unproven - compare recent sold prices on the street yourself before pricing an offer around it.
On later completions, homes listed below their estimate sold at the same share of the asking price as the rest.
3. 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.
