Lease term
Below common lender thresholds, remediation can be costly or impossible without extension.
Money
Ground rent, service charge, reserve funds, and major works consultations tell you future cash calls.
Management
Who runs the building, how disputes are handled, and whether major projects are planned.
Building safety
Where relevant, understand EWS1 history and remediation status in line with professional advice.
Documents
Management packs are often slow. Start early and store what you receive in your Property Passport if you proceed.
