Property data, United States, all 3,100+ counties
Property Records (Assessor + Recorder)
Owner, characteristics, assessed value, sale history and mortgage for every US parcel, joined on a stable parcel key you can build on.
The assessor side carries the physical property: land use, square footage, beds and baths, year built, lot size, assessed and market values, tax amounts, and the owner of record with mailing address. The recorder side carries every deed and mortgage document recorded against the parcel, so you can see who bought, who sold, what they paid and who lent.
Everything is keyed on a persistent property identifier that also appears in our signal files, permits, valuations and owner-contact data. That is the difference between a database and a pile of CSVs: a listing signal can be joined to the owner's mailing address without fuzzy matching.
We license the full national file, state and county cuts, or filtered pulls such as owner-occupied single-family with a purchase in the last 24 months.

How it is built
We aggregate county assessor and recorder data through licensed national feeds and fill gaps with direct county pulls where the national feeds lag. Deeds are deduplicated against change-data-capture noise so a transaction appears once.
Land-use codes are normalized so a query for residential means the same thing in every county.
Questions we get
What does 'owner-occupied' mean in your file?
The owner's mailing address matches the property's situs address after normalization. We also flag corporate and trust owners separately, since 'LLC' in a name is not always a business.
Can you unmask an LLC owner?
Often. We chase the mailing address and cross-reference recorder, permit and professional-profile data. It is a service, not a column, and we quote it per batch.
