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 3900/mo (range 3450-4400)

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.

This application seeks a Certificate of Lawful Proposed Use or Development confirming that the proposed internal reconfiguration of small parts of the building does not constitute development within the meaning of Section 55 of the Town and Country Planning Act 1990 because the works comprise internal alterations only and do not result in a material change of use. The proposal involves minor adjustments to the internal layout of Units 1-6. The works comprise the relocation of internal partitions and the closing and opening of internal doorways to redistribute small areas of floor space between adjacent dwellings. These alterations simply redistribute small areas of existing floor space between neighbouring flats to improve their internal layout. Each dwelling will remain a separate self-contained Class C3 unit before and after the works.
