Data and methods

Sources

Every row records its sources and the date it was last checked. The full list with counts is on Data sources.

How managers are identified

1. Building list. Apartment communities come from county appraisal district rolls (5+ units), plus HUD, USDA and TDHCA records.
2. Manager evidence. Code reads each property's website footer, copyright line, "managed by" text, privacy-policy and tour-booking domains, and checks managers' own published property lists. Government housing records name the management agent directly.
3. Confidence. Each match gets a confidence score. Clear cases are accepted automatically; ambiguous ones are reviewed. Each property page says how its manager was identified.
4. HOAs. Texas law requires each HOA to file a management certificate naming its manager. Certificates are read with on-device text recognition and rules built for the certificate's fixed format; unclear ones are reviewed. The latest certificate per HOA wins.
5. Hotels and restaurants. Owners come from Texas Comptroller permits. Related companies are grouped by taxpayer number, shared business mailing address and name.

Quality bar

A property page is indexed for search only when its name and address are confirmed and it has a manager (confidence 0.8 or higher), an ownership group or a unit or room count, plus at least four facts. Company pages need at least 3 properties and hubs at least 10 rows. Pages below the bar stay available but are marked noindex; the rows remain in the files.
