Verdict

Derived from HomePortfolio scores

Flat B14 earns an INVESTIGATE rating with HP Score 80/100. Investment score 71/100 reflects strong fundamentals. Crime intensity is low. Walkability is excellent (99/100). 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

Not scored as an opportunity

We will not put a number on this one.

3 live adverts with different prices, types or bedrooms on one UPRN (£290,000-£300,000) - several homes collapsed onto one address, so the UPRN's valuation describes none of them

Withholding a score is deliberate. A number built on missing or stale inputs would look more certain than the evidence allows.

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 1.33 - 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

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

Plan

Before you offer

1. 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.

Magnolia in the rear garden- Reduce crown by 1.5 Metres on North, west and southern aspects Lift crown to a height of 3 Metres from ground level This tree has a twin stem that twist across each other, with a bark inclusion at the division, reducing the crown will reduce forces at the division reducing the risk of the tree failing at this point during storm condition. In addition the tree has out grown its position in the small garden and the crown reduction would be in keeping with the character and dimensions of the garden
