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. Set your walk-away price before viewing - above £240,000 the deal stops scoring well.
Computed by re-running the score at higher prices.
3. 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.
4. Commission a full structural survey, not a basic condition report.
The score prices market evidence, not the fabric of the building.
