ATTOM Data Solutions is a U.S.-based property data aggregator and licensor that compiles parcel-level real estate information for use by investors, lenders, insurers, governments, and technology firms. The company curates transactional records, deed histories, tax assessments, foreclosure filings, and neighborhood attributes to support underwriting, analytics, compliance, and market research. Its datasets are consumed by platforms in the financial services, title insurance, real estate brokerage, insurance, and analytics sectors.

Overview

ATTOM supplies nationwide property and neighborhood data covering residential and commercial parcels, integrating records such as deeds, mortgages, tax liens, foreclosure actions, and historical sales. Major markets for its data include mortgage banking, title and escrow, property and casualty insurance, risk management, equity investment, and software-as-a-service providers. The firm positions itself amid competitors and adjacent organizations including CoreLogic, Black Knight, Inc., Zillow Group, CoStar Group, and Realtor.com vendors, seeking to differentiate via comprehensive coverage and normalized schemas used by clients such as Wells Fargo, Bank of America, JP Morgan Chase, and technology partners like Amazon Web Services.

History and corporate development

The company traces its origin to a consumer-facing foreclosure marketplace founded in the early 2000s, later evolving into a business-to-business data provider. Key corporate milestones include expansion of county-record coverage across the United States and rebranding and strategic acquisitions to broaden tax, deed, and neighborhood datasets. Management and strategic financing rounds involved investors and private-equity actors common in technology and real estate sectors, with board and executive teams drawing from leadership with backgrounds at firms such as Moody's Analytics, Fiserv, Experian, and digital media companies. The firm has navigated consolidation trends in the property-data market exemplified by mergers and acquisitions involving CoreLogic and Black Knight, Inc..

Products and services

Products emphasize parcel-level licensing, bulk data feeds, APIs, and curated insights. Offerings typically listed by the company include property-level data, deed and mortgage history, foreclosure and REO records, tax assessor attributes, building characteristic data, historical transactions, and neighborhood indicators such as school zones and flood risk. Verticalized solutions support title insurance underwriting used by vendors collaborating with First American Financial Corporation, Fidelity National Financial, and mortgage servicing platforms adopted by Ocwen Financial Corporation and Quicken Loans (now Rocket Mortgage). Analytics and modeling suites are integrated into risk workflows used by insurers like Progressive Corporation and Allstate Corporation.

Data sources and methodology

ATTOM aggregates public-record feeds from county recorder, assessor, clerk, and probate offices across jurisdictions in the United States, supplemented with proprietary normalization, deduplication, and geocoding processes. The company applies data engineering and quality assurance practices akin to methodologies employed by data firms such as LexisNexis and FactSet: schema mapping, address standardization using postal authority references, parcel geolocation against US Geological Survey and commercial basemaps, and temporal reconciliation for title chains. Additional inputs can include MLS feeds from local boards like the California Regional Multiple Listing Service, hazard layers from agencies such as the Federal Emergency Management Agency, and demographic overlays referencing censuses conducted by the United States Census Bureau.

Partnerships and clients

ATTOM has entered distribution and technology partnerships to scale delivery and product integration, leveraging cloud platforms, data marketplaces, and distribution channels. Strategic relationships include cloud providers like Microsoft Azure and Amazon Web Services, analytics partners and integrators in the proptech ecosystem such as CoStar Group subsidiaries, and fraud-prevention vendors competing with Experian products. Client bases span national and regional banks, mortgage originators, title insurers, real estate brokerages, investment firms including hedge funds and private-equity managers, along with municipal agencies and academic researchers at institutions like Harvard University and Stanford University that analyze housing markets.

Privacy, compliance, and controversies

As a compiler of public records and sensitive financial indicators, ATTOM operates within regulatory frameworks including state recording laws, federal statutes referenced by agencies such as the Consumer Financial Protection Bureau, and privacy expectations shaped by jurisprudence and statutes like the Gramm–Leach–Bliley Act. Data licensing and reuse have prompted scrutiny over consumer opt-out options and the commercial resale of public records, a debate echoed in controversies around data brokers including ChoicePoint and Acxiom. The company has navigated compliance with data-access policies of county registries and addressed concerns from civil-liberties advocates and industry stakeholders over aggregation, re-identification risk, and downstream use in housing and lending decisions.

Awards and industry recognition

The firm and its products have been cited in industry analyses and awarded by trade organizations and analytics conferences recognizing data breadth, delivery, and innovation. Recognition often parallels lists and rankings compiled by entities such as Forbes, Inc., Deloitte industry reports, and real estate technology awards presented at conferences like Inman Connect and Mortgage Bankers Association events. Peer comparisons and third-party evaluations cite coverage, update frequency, and integration capabilities relative to vendors such as Black Knight, Inc. and CoreLogic.
