Why this could be an opportunity

Low confidence0 independent sourcesLead to verifyListing checked 12 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: leasehold with no service charge disclosed - the stress test assumes GBP 0. 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

£225,000£345,000

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.

Score at this price: 19

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 1.38 - clears the usual 1.25 test. These are your assumptions, not evidence: only the pre-filled rent and price come from the record.

What could kill this deal

Score confidence is low
largely a single source - treat the number as a prompt, not a conclusion

Stress margin needs verification before you rely on it

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.

G1 (4x Horse Chestnuts): Reduction of 2.5m reduction in overall height and a 2m reduction in lateral growth to all four trees.
Pending
26/03174/CAT
T1 and T2 Horse Chestnut: reduction to both trees by approximately 2.5 metres in height and 2 metres in lateral spread. T3 Lime Tree: reduction by approximately 5 metres in height and 1.5 metres in lateral spread. The works are considered necessary due to the tree's significant overhang towards the neighbouring property, its pronounced lean and concerns regarding the condition of the basal area, where brittle cinder has been identified. The proposed reduction aims to reduce excessive crown weight, alleviate mechanical loading on the main stem and primary branches, and minimise the potential for limb failure.
