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 3250/mo (range 2900-3600)

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.
