Opportunity

Why this could be an opportunity

Low confidence0 independent sourcesLead to verifyListing checked 9 Nov 2026

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

Check before relying on this score: the estimate sits 23% above the ask; lead to verify: the advert has 6 bedrooms but the valuation snapshot describes 4 - an extension, conversion or HMO the evidence does not reflect, or a different home. It ranks after every home whose inputs are verified.

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.

Economics

What happens to your money

Price sensitivity

£937,500£1,437,500

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: 10

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 1.26 - clears the usual 1.25 test. These are your assumptions, not evidence: only the pre-filled rent and price come from the record.

Risks

What could kill this deal

Score confidence is low
largely a single source - treat the number as a prompt, not a conclusion
Rental economics needs verification before you rely on it

Rental economics needs verification before you rely on it
sale estimate 23% above the ask on the same snapshot - verify the rent describes this home

Plan

Before you offer

1. Get two written rental appraisals from local lettings agents.
The market estimate this rent rides on sits far above the asking price, so the rent may describe a different home.
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.
