Build-to-Rent Community Register: free sample (Tensorust LLC)
2,323 build-to-rent style clusters (35,495 homes built 2015+, $9,140,080,265) held by one owner group per street.
Headline: Build-to-rent communities do not show up as one record anywhere: they sit on the county roll as dozens of parcels titled to one or several LLCs.
This repository is a free teaser, not the dataset. It holds 25 example rows and a summary table with no names in it. The full file has 2,323 rows and is sold by Tensorust LLC: https://tensorust.com/datasets/btr-community-register/.

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.
