What we could establish

Rental economics6.2/40
gross yield 6.1%; range width penalty ×0.70; the estimate this rent rides on sits 34% above the ask - check the rent describes the advertised home
- valuation_snapshotsrent estimate 4200/mo (range 3700-4750)· as of 12 Oct 2026· verify before relying on this
- valuation_snapshotssale estimate 34% above the ask on the same snapshot - verify the rent describes this home· as of 12 Oct 2026· verify before relying on this
Stress margin0/30
stressed cash flow -523/mo, -12% of rent (6.75% on a 75% loan; no service charge or ground rent disclosed); fails the stress - earns nothing

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 4200/mo (range 3700-4750)

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.
