Property owner data originates from county tax assessor and recorder records. For properties held by LLCs, shell companies, or trusts, Realie provides structured owner names, owner mailing addresses, and parent entity resolution across 180M+ U.S. properties through a normalized REST API, CLI, and MCP server.
Raw county assessor tax rolls list owner names as recorded, often truncated or formatted inconsistently (e.g., "SMITH JOHN T & MARY E" vs "SMITH JOHN T ET AL"). Furthermore, commercial and residential investment properties are frequently held under single-purpose LLCs. Realie’s ownership pipeline parses raw owner strings into structured individual and corporate parties, normalizes mailing address clusters, and identifies controlling parent entities across 3,100+ counties.
Tax assessor rolls record owner strings formatted for local tax billing. These strings routinely mangle party roles, split names across arbitrary character boundaries, or bundle multiple individuals into one field.
Realie applies an entity resolution pipeline that extracts individual parties (first name, last name, suffix) and corporate entities (LLCs, LPs, Corporations, Trusts). This turns unstructured text into clean, queryable arrays of owner entities and roles.
Real estate portfolios often isolate individual assets inside single-purpose entities (e.g., "123 MAIN ST LLC"). By clustering owner mailing addresses and cross-referencing corporate filings, Realie links related SPVs back to their true parent entity or portfolio owner.
This allows analysts and developers to query portfolio holdings by owner name or mailing address across all 50 states.
