How to Find the Owner of a Commercial Property: 7 Reliable Methods

Start with the county parcel record, confirm the grantee on the latest recorded deed, and then trace any LLC through the relevant Secretary of State. Treat a database match, registered agent, tax-mailing address, or leasing contact as a lead until at least two independent records agree. LeaseLineage does not provide ownership data; verified prospects can be added to an outreach campaign after the research is complete.
