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. Treat the gap to the estimate as unproven - compare recent sold prices on the street yourself before pricing an offer around it.
On later completions, homes listed below their estimate sold at the same share of the asking price as the rest.
2. Fill the rental economics gap before relying on the score.
no rent estimate available
3. Fill the stress margin gap before relying on the score.
no rent to stress
4. 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.
