Property Ownership Data
Verification. Validation. Occupancy.ATTOM provides you with accurate property ownership data, including all the relevant property owner information. Whether a property is owned by an individual, a couple, multiple people, partners or a company, verification is a key component to transacting business in the real estate industry. Validating the owner/owners of a property is essential to buying, selling, financing, building and insuring, and is equally important to vendors looking to market to owners and renters.

Owner Names

Tax Mailing Address
Acquired from publicly recorded documents (Deed), the mailing address is available as the primary contact address for the property owner by the county assessor for tax purposes.
Exemptions
Counties will allow property owners to apply for a variety of exemptions, including the basic Homeowner’s exemption, Senior, Veteran, and Disabled, as the most common. The exemptions reduce an owner’s property tax liability, which translates into a reduction in their property tax.
Occupancy
Understanding whether residential properties (Single Family Residence, Condominium, Townhome) are occupied by the property owner, or not (rental / vacation residences).
Vesting Details
While each state has its own unique language when it comes to vesting titles, vesting related to real estate ownership is the way a homeowner takes title of their property, such as Joint Tenants / Tenants in Common / Community Property.
What is Property Owner Data?
Property owner information data encompasses data on the history of homeownership of a particular property. Property ownership data shows who owns the property, whether that be an individual, couple, a number of people, or a company. This data is typically used to verify property ownership.
