This repository is a **free teaser**, not the dataset. It holds 25 example rows and a summary table with no names in it.

All datasets: https://tensorust.com/datasets/ ## Method and limits Parcels with year_built of 2015 or later owned by business entities (individuals and trusts removed). Owner names resolve to control groups through the Tensorust control graph (shared addresses, registered agents, SEC subsidiary lists). A cluster is one group, county and street name with 5 or more such homes. by_county.csv sums clusters, homes and value by county. It is a street-level proxy, not a plat or subdivision match. Not individual homeowner data: only business-entity owners are included. Not a plat-level community list: a long street can hold two communities, and one community can span streets. Not proof the homes are rented: builder inventory and model homes can appear. Market values are county roll values, not appraisals. ## Sources - County appraisal rolls (2025 and 2026 roll years): Harris (https://hcad.org/pdata/), Dallas (https://www.dallascad.org/), Tarrant (https://www.tad.org/), Collin (https://www.collincad.org/), Travis (https://traviscad.org/), Bexar (https://www.bcad.org/), Maricopa (https://mcassessor.maricopa.gov/), Clark (https://www.clarkcountynv.gov/assessor), Gwinnett (https://www.gwinnettassessor.manatron.com/), Duval (https://www.coj.net/departments/property-appraiser), Hillsborough (https://www.hcpafl.org/), Orange (https://ocpaweb.ocpafl.org/), Mecklenburg (https://www.mecknc.gov/AssessorsOffice), Fulton, Cobb, DeKalb, Shelby - Texas Comptroller active franchise taxpayers (control graph links): https://data.texas.gov/ - SEC EDGAR Exhibit 21 subsidiary lists (control graph links): https://www.sec.gov/edgar/search/ - Tensorust control graph (Nov 2026 build) ## License The sample and summary here are free to view, analyze and cite with attribution to "Tensorust LLC, https://tensorust.com/datasets/btr-community-register/".
