Open housing market data
The same numbers behind every page on this site, published as free, open datasets — county, metro and state level. CC‑BY‑4.0, mirrored on four hosts so they’re easy to find and easy to cite.

US State Housing Market Snapshot
51 states — median-of-county price/DOM + YoY (through 2026-05-31)
A state-by-state summary derived from our county-level snapshot: for each state, the median across its counties of median sale price, list price, price-per-sqft, days on market and year-over-year change. Median-of-county-medians, not a sales-weighted statewide index — stated explicitly so it is never mistaken for one.
