Why this could be an opportunity

Low confidence0 independent sourcesLead to verifyListing checked 4 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.

Risks

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
costs not disclosed by the advert

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.

Pending
26/00073/TCA
T1 - Conifer (Unsure of species, possibly Leylandii or Cedar) on eastern boundary in rear garden. Remove tree with a view to planting a smaller, broadleaved alternative in its place. Resident is in the process of selling the property and has had consistent feedback that potential buyers are being put off by the how much light the tree takes up in the garden and through the rear windows. Tree was originally planted by resident's father. T2 - Leylandii Hedge on northern boundary in front driveway. Remove tall growth bringing height down by 4-5m down into the managed part of hedgerow below. Lower portion has been historically managed by the resident but the tall growth off of the back of the hedge has not been able to be managed and has grown too tall, interfering with guttering and blocking light to the windows at the front of the house.
