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.
