Verdict

Derived from HomePortfolio scores

Gradon earns an INVESTIGATE rating with HP Score 80/100. Investment score 73/100 reflects strong fundamentals. Crime intensity is very low. Walkability is limited (50/100). Flood risk is not assessed: check the Environment Agency long-term flood map before offering. Tenure is freehold. Every figure here comes from the live HomePortfolio API; anything it does not publish is left out.

Withholding a score is deliberate. A number built on missing or stale inputs would look more certain than the evidence allows.

Risks

What could kill this deal

Score confidence is low
largely a single source - treat the number as a prompt, not a conclusion
Valuation edge could not be scored
estimate confidence LOW below scoring floor
Rental economics needs verification before you rely on it
rent estimate 6450/mo (range 5700-7150)

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. Fill the valuation edge gap before relying on the score.
estimate confidence LOW below scoring floor
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.
