Verdict

Derived from HomePortfolio scores

12 Mollison Square earns an INVESTIGATE rating with HP Score 67/100. Investment score 67/100 reflects moderate fundamentals. Crime intensity is moderate. Walkability is limited (63/100). Flood risk is not assessed: check the Environment Agency long-term flood map before offering. Tenure is leasehold. Every figure here comes from the live HomePortfolio API; anything it does not publish is left out.

We will not put a number on this one.

listing is 'Under offer' - sale already progressing, not an actionable opportunity

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

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 2.47 - clears the usual 1.25 test. These are your assumptions, not evidence: only the pre-filled rent and price come from the record.

Risks

What could kill this deal

Score confidence is low
largely a single source - treat the number as a prompt, not a conclusion

Property risk deep-dive →flood, subsidence, crime, environment - the full domain

Plan

Before you offer

1. 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.
