This rests largely on a single source. Treat the score as a prompt to investigate, not a conclusion.

Economics

What happens to your money

Price sensitivity

The same scorer re-run at hypothetical asking prices, holding rent, comps and listing history constant. Not a prediction of what the seller would accept.

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 1.26 - clears the usual 1.25 test. These are your assumptions, not evidence: only the pre-filled rent and price come from the record.

Risks

What could kill this deal

Seller motivation could not be scored
context, not scored: 0 price cut(s), 71 days on market; homes with a cut sold 0.2-0.3pp further below the cut ask, which is not an edge

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. Treat the gap to the estimate as unproven - compare recent sold prices on the street yourself before pricing an offer around it.
On later completions, homes listed below their estimate sold at the same share of the asking price as the rest.
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.

TPO 406 identifies a false acacia in the rear garden. The submitted plan and description do not clearly distinguish the protected tree from the other trees or adequately specify all proposed works. The Council has recorded this case as withdrawn in Uniform. No no-objection outcome has been issued. The applicant has been asked to submit a clearly identified TPO application and, where required, a separate section 211 notice.
