Verdict

Derived from HomePortfolio scores

34A Hertford Road earns an INVESTIGATE rating with HP Score 72/100. Crime intensity is very low. Walkability is limited (17/100). Flood risk is not assessed: check the Environment Agency long-term flood map before offering. 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
no market estimate available
Rental economics could not be scored
no rent estimate available

Plan

Before you offer

1. Fill the valuation edge gap before relying on the score.
no market estimate available
2. Fill the rental economics gap before relying on the score.
no rent estimate available
3. Fill the stress margin gap before relying on the score.
no rent to stress
4. 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.
