Owner Lists show who holds title to each unit in a building, how long they have held it and what they last paid. Where the tax record matches the current owner, Boston lists add the tax mailing address, residential exemption, assessed value and tax, and Miami lists add the mailing address, homestead exemption and just value.

Where public records name a person behind a trust or LLC, the list shows that person. That person is not necessarily the beneficial owner.
Search an owner’s name to see every unit they hold. Names match by name, not identity, so check the result is the person you mean.
Download the list as a CSV, up to 12 exports and 2,500 rows in any 24 hours, or share it with a link.
Start with the whole building, then filter by how the owner bought, how they hold title, how many units they own and how long they have held.
In Boston, a purchase mortgage recorded within three business days of the deed means financed. In Miami the label appears only where the record proves it. New York lists don’t carry it.
