Opportunity

Why this could be an opportunity

Low confidence1 independent sourceLead to verifyListing checked 4 Nov 2026

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 19% above the ask. It ranks after every home whose inputs are verified.

Economics

What happens to your money

Price sensitivity

£169,000£258,500

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.

Your assumptions

Purchase price£225,000

At the asking price

Monthly rent£1,300/mo

Evidenced range £1,200-£1,400

Interest rate5.4%

Loan to value75%

Cash required: £70,800
Net cash flow: £141/mo
Cash on cash: 2.4%
Score at this price: 31

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 1.71 - 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

Score confidence is low
largely a single source - treat the number as a prompt, not a conclusion
Rental economics needs verification before you rely on it

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.
