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 could not be scored
no rent estimate available

Plan

Before you offer

1. Fill the valuation edge gap before relying on the score.
estimate confidence LOW below scoring floor
2. Fill the rental economics gap before relying on the score.
no rent estimate available
3. Fill the stress margin gap before relying on the score.
no rent to stress
4. 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 trunk is also pressing against the boundary wall with No.59 Spencer Park and is likely to cause damage if retained. T2 + T3 Himalayan Birch (x2) Crown lift by 1.5m. Reason: To allow more light to the plants below. T4 Cherry (x1) Reduce crown by 1.5m. Reason: To redress the balance as supressed by the Birches. T5 Paulownia (x1) Crown lift by 1.5m.
