Why this could be an opportunity

Reduced confidence2 independent sourcesLead to verifyListing checked 4 Nov 2026

Fewer independent sources agree, or a component could not be scored.

Check before relying on this score: 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): 2.18 - clears the usual 1.25 test. These are your assumptions, not evidence: only the pre-filled rent and price come from the record.

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.
2 price cut(s) recorded on the listing history.
3. Set your walk-away price before viewing - above £149,000 the deal stops scoring well.
Computed by re-running the score at higher prices.
4. 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.
