Verdict

Derived from HomePortfolio scores

The Cottage earns an INVESTIGATE rating with HP Score 62/100. Investment score 53/100 reflects moderate fundamentals. Crime intensity is very low. Walkability is limited (9/100). Flood risk is not assessed: check the Environment Agency long-term flood map before offering. Every figure here comes from the live HomePortfolio API; anything it does not publish is left out.

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

Economics

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): 0.64 - 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.
