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 600/mo (range 550-650)

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.

The proposals comprise the removal of the existing signage located on the clock elevation, currently formed of two large timber-framed panels measuring approximately 1700 x 3200mm with assumed vinyl inserts. The existing signage is to be replaced with a reduced timber-framed panel measuring 1700 x 1000mm. In addition, a modest projecting sign measuring 600 x 500mm is proposed to improve visibility at street level. All new signage will be constructed from materials and detailing appropriate to the heritage context, with the intention of reducing visual clutter and better respecting the character of the listed building.
