Why this could be an opportunity

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

£337,500£517,500

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.

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 2.04 - 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
Seller motivation could not be scored
context, not scored: 1 price cut(s), 140 days on market; homes with a cut sold 0.2-0.3pp further below the cut ask, which is not an edge

Property risk deep-dive →flood, subsidence, crime, environment - the full domain

Plan

Before you offer

1. Ask the agent why the price was reduced and whether a previous sale fell through.
1 price cut(s) recorded on the listing history.
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.

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.
