What we could establish

Rental economics0/40
gross yield 3.4% on contractual rent (listing-disclosed tenancy); contractual 2700/mo far above the 950/mo estimate - credited at the 1.3x cap, verify
- listing_factscontractual rent 2700/mo (tenanted)· as of 2 Nov 2026· verify before relying on this
Stress margin0/30
stressed cash flow -1,057/mo, -86% 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
contractual rent 2700/mo (tenanted)

Plan

Before you offer

1. Get two written rental appraisals from local lettings agents.
The rent estimate rests on area-level evidence, not lettings on this street.
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.
