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

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 0.89 - 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.
