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 3950/mo (range 3550-4300)

Plan

Before you offer

1. Get two written rental appraisals from local lettings agents.
The market estimate this rent rides on sits far above the asking price, so the rent may describe a different home.
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.
