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

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. Ask the agent why the price was reduced and whether a previous sale fell through.
1 price cut(s) recorded on the listing history.
3. Fill the valuation edge gap before relying on the score.
estimate confidence LOW below scoring floor
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.

Thin crown density by approx. 20%. 1 x Amelanchier (T2) - Formative prune by reducing leader stems by approx. 1m, to produce a more even crown height line. Tip prune, reducing by up to 0.3m to shape. REAR GARDEN: 1 x Hoheria (T4) - Reduce crown height by approx. 1m - 1.2m. Thin crown density by approx. 25% by means of removing overcrowded stems. Trim sides hard back, up to approx. 0.7m whilst preserving as much fine structure on the branch ends. Raise crown by up to 0.5m, ensuring low screen is preserved whilst viewing the tree from the ground floor level.
