Opportunity

Not scored as an opportunity

We will not put a number on this one.

estimate implies a 95% discount - beyond plausibility (gate 50%); suspected unit/basis mismatch, not a realisable edge

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

Score at this price: -

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 22.96 - clears the usual 1.25 test. These are your assumptions, not evidence: only the pre-filled rent and price come from the record.

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.
