Why this could be an opportunity

Low confidence1 independent sourceListing checked 6 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

£94,000£144,000

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: 35

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 1.90 - 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.

Remove roots and install a root barrier along the road-side boundary of the tennis courts at Mapperley Park Tennis Club. Works comprise excavation of a 300mm wide trench to a depth of 1m, clean pruning of any roots encountered, installation of a Geosynthetics RootBlock barrier, and reinstatement of the affected surfacing. The works are intended to prevent further root-related damage to the court surface and address existing trip hazards. All excavation and root pruning shall be undertaken in accordance with BS 5837:2012, with advance notice given to Tree Services to allow supervision of any significant root pruning. On balance, the works represent a pragmatic solution to ongoing infrastructure damage whilst seeking to minimise impacts on the adjacent trees.
