Draft:Attom

The company was founded in 1996 as RealtyTrac, initially focusing on foreclosure data for investors, real estate agents, and consumers.^[1] In 2015, Rob Barber became chief executive officer and led the creation of the ATTOM Data Warehouse, following the company’s access to newly sourced tax, deed, and mortgage data.^[1][4][5] This access came about as a result of licensing arrangements required as part of a Federal Trade Commission settlement involving CoreLogic.^[1]

In 2016, RealtyTrac rebranded as ATTOM Data Solutions to reflect a broader focus on property data beyond foreclosures.^[1][5] After the rebrand, ATTOM Data Solutions operated as the parent for RealtyTrac, Home Disclosure, and Homefacts, and used data from these and other sources to expand the ATTOM Data Warehouse.^[5] Over roughly four years, the company shifted from offering primarily foreclosure search services to supplying a wider range of property data products.^[1][5]

In 2018, ATTOM acquired Onboard Informatics, a provider of neighborhood and related real estate data.^[6] In 2019, the company was acquired by private equity firm Lovell Minnick Partners, with additional financing from Monroe Capital.^[6][7][8] Prior owners included Renovo Capital and Rosewood Private Investments.^[6] In 2019, ATTOM also announced a partnership with Clear Capital to make multiple listing service (MLS)–based valuation data available to clients under licensing arrangements.^[9]

In 2020, ATTOM acquired San Diego–based Home Junction, adding school and neighborhood boundary data, crime information, points of interest, and demographic datasets to its warehouse.^[10] That year it also launched a searchable database of building permits for nearly 100 large U.S. cities and reported coverage of more than 200 million residential and commercial properties nationwide.^[11]

In 2021, ATTOM acquired GeoData Plus, a property research and valuation application containing sales comparisons, liens, violations, property photographs, maps, and zoning information.^[11] Prior to the acquisition, GeoData Plus had used ATTOM data for some of its functions.^[11]

In 2022, ATTOM sold its consumer-facing websites, including RealtyTrac and Homefacts, to Nations Info as part of a shift toward a data-licensing–focused model.^[3][12] Nations Info entered into a multi-year agreement to license ATTOM data as part of the same transaction, effective 15 July 2022.^[12] Later in 2022, ATTOM integrated loan originator information from the Nationwide Multi-State Licensing System and Registry (NMLS) into its platform and acquired property data company Estated.^[13]

In February 2023, ATTOM announced an integration of its foreclosure and mortgage data with analytics provider Powerlytics, including the introduction of propensity-to-default analytics.^[14] In 2024, the company added building footprint data to extend its geospatial data offerings.

ATTOM provides property data products that include automated valuation models (AVMs), neighborhood and school boundary datasets, building footprint and other geospatial overlays, and application programming interfaces (APIs) for integrating its data into client systems.^{[1][2][10][11]}

The company publishes the U.S. Foreclosure Market Report, which is based on data from more than 3,000 counties and is described as covering over 99 percent of the U.S. population.^[15] The report tracks foreclosure filings at three stages: default or pre-foreclosure, auction, and real estate owned (REO).^[15] ATTOM also produces other market reports, including analyses of housing affordability in the United States.^[16]

The ATTOM Data Warehouse is structured as a modular database, enabling clients to license and access selected datasets rather than the entire warehouse.^[1]

ATTOM was an early adopter of Microsoft SQL Server 2016 in the Azure cloud environment for its data warehouse operations.^[1] This infrastructure reduced the processing time for some data requests compared with previous configurations.^[1] In June 2021, the company introduced ATTOM Cloud, a cloud-based platform designed to provide clients with managed access to its property data products.^[11]
