Derived from HomePortfolio scores

Talisman earns an AVOID rating with HP Score 75/100. Investment score 62/100 reflects moderate fundamentals. Crime intensity is low. Walkability is good (76/100). Flood risk is not assessed: check the Environment Agency long-term flood map before offering. Tenure is leasehold. Every figure here comes from the live HomePortfolio API; anything it does not publish is left out.

Opportunity

Why this could be an opportunity

Low confidence1 independent sourceLead to verifyListing checked 5 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: leasehold with no service charge disclosed - the stress test assumes GBP 0. It ranks after every home whose inputs are verified.

4 of 4 components scored. Ranks on gross yield, the stress margin, risk and disclosed facts. A pricing claim earns only its measured edge: today 0 for the market estimate and at most +0.5pp for sold evidence. The score itself is not yet checked against the outcomes of homes it scored.

Economics

What happens to your money

Price sensitivity

£300,000£460,000

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.

Score at this price: 31

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.

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
rent estimate 2450/mo (range 2350-2600)
Stress margin needs verification before you rely on it
costs not disclosed by the advert

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. 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.
