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

Plan

Before you offer

1. Ask the agent why the price was reduced and whether a previous sale fell through.
1 price cut(s) recorded on the listing history.
2. 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.
3. Fill the rental economics gap before relying on the score.
no rent estimate available
4. Fill the stress margin gap before relying on the score.
no rent to stress
