Boleyn House earns an INVESTIGATE rating with HP Score 68/100. Investment score 51/100 reflects moderate fundamentals. Crime intensity is very low. Walkability is limited (25/100).

Every figure here comes from the live HomePortfolio API; anything it does not publish is left out.

Why this could be an opportunity

This rests largely on a single source. Treat the score as a prompt to investigate, not a conclusion.

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

£825,000£1,265,000

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.

Your assumptions

Purchase price£1,100,000

At the asking price

Monthly rent£2,700/mo

Evidenced range £2,250-£3,150

Interest rate5.4%

Loan to value75%

Cash required: £385,050
Net cash flow: -£1,843/mo
Cash on cash: -5.7%
Score at this price: 15

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 0.73 - below 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 2700/mo (range 2250-3150)
Seller motivation could not be scored
no listing-history inputs (first published date, price changes)

Property risk deep-dive →flood, subsidence, crime, environment - the full domain

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.
