This rests largely on a single source. Treat the score as a prompt to investigate, not a conclusion.
Check before relying on this score: the estimate sits 22% above the ask; lead to verify: leasehold with no service charge disclosed - the stress test assumes GBP 0. It ranks after every home whose inputs are verified.

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 1.81 - clears the usual 1.25 test. These are your assumptions, not evidence: only the pre-filled rent and price come from the record.

What could kill this deal

Plan
Before you offer
1. Get two written rental appraisals from local lettings agents.
The market estimate this rent rides on sits far above the asking price, so the rent may describe a different home.
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.
