Verdict

Derived from HomePortfolio scores

45 Armstrong Close earns an INVESTIGATE rating with HP Score 80/100. Investment score 67/100 reflects moderate fundamentals. Crime intensity is very low. Walkability is limited (69/100).

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 confidence0 independent sourcesLead to verifyListing checked 3 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.

Economics

What happens to your money

Price sensitivity

£124,000£189,500

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£165,000

Monthly rent£750/mo

Evidenced range £700-£800

Score at this price: 18

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 1.35 - 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

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.
