Data Foundation
Transparent by construction.
We use only federal and open data sources. No paid data providers, no licensed feeds. Every series is documented below, with cadence, coverage, and link to the upstream authority.
Data foundation
Every lot price cites its work.
Comp transactions, active permits, MLS pricing, federal jobs and rates data — every number on the platform traces back to a public source you can audit. Builders defend the price, not us.
