Free housing data — download & API
Every number on Real Estate Price Map is built on public data, and we give it back. Download 3,072 US counties of home-price data as CSV or JSON — free, no sign-up, no key.
Use it as an API
The JSON is served with open CORS headers, so you can fetch it straight from any site or app — no key, no rate limit:
fetch("https://realestatepricemap.com/data/open/us-county-home-prices.json")
.then(r => r.json())
.then(d => console.log(d.count, "counties", d.as_of));What's in the file
