License & coverage

Lists are licensed to a single firm — no resale or redistribution. Everything is computed from the county's public records (assessments, permits, appeals, deeds); coverage today is Winnetka, IL. A matching property is a research lead, not a prediction that its owner needs work or will become a customer.
