Data sources

REAIGENT7 area insights are compiled from public government, academic, and industry research datasets. Every figure shown on a listing or area page comes from one of the sources below. We aggregate, normalize, and surface them through the AI assistant on listing and area pages — we do not modify the underlying data.

Some fields these publishers include (demographic, income, and similar protected-class proxies) are never shown to buyers or given to the AI — see our Fair Housing Policy.

Each source is refreshed on its publisher’s schedule — monthly for market and home-value data; annually for fair market rents, air quality, and most Census and federal datasets; mortgage-rate averages periodically. Climate normals and hazard maps are long-term datasets that change only when their publishers revise them. For binding decisions on a specific property — pricing, contracts, inspections — REAIGENT7 always defers to the licensed listing agent. See the Terms of Service for full attribution and use terms.
