Why this could be an opportunity

Low confidence0 independent sourcesListing checked 2 Nov 2026

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

£180,000£276,000

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.

Purchase price£240,000

At the asking price

Monthly rent£1,200/mo

Evidenced range £1,150-£1,300

Net cash flow: £21/mo
Cash on cash: 0.3%
Score at this price: 22

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 1.48 - 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. 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.
