Verdict

Derived from HomePortfolio scores

21 Mays Lane earns an INVESTIGATE rating with HP Score 74/100. Investment score 64/100 reflects moderate fundamentals. Crime intensity is very low. Walkability is limited (47/100). 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.

What we could establish

claims [AVM -35.0% (MEDIUM)] → measured edge -0.12pp of the ask; on later-registered sales an AVM discount carried no edge and a sold-evidence gap at most +0.5pp; asking more than 10% above the estimate (measured -0.33pp)

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
Rental economics could not be scored
no rent estimate available
Stress margin could not be scored
no rent to stress

Plan

Before you offer

1. Fill the rental economics gap before relying on the score.
no rent estimate available
2. Fill the stress margin gap before relying on the score.
no rent to stress
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.
