A research tool that takes a Rightmove listing URL and returns structured due diligence data for UK leasehold flats. It pulls from HM Land Registry, EPC registers, council tax records, flood maps, and building safety databases to score properties across lease quality, running costs, comparable sales, energy efficiency, and market position. The verdict includes lease extension math, service charge red flags, and price per square meter against local comps. Useful when you need to surface hidden leasehold risks like the 80-year marriage value cliff, Section 20 major works, or cladding exposure before instructing a solicitor. Saves the manual work of checking a dozen public registers per property and flags the actual monthly cost of ownership in pounds.
