Home Value, By Source

The Census Bureau's American Community Survey (2023 5-year estimate) puts Rock Island's median home value — across all owner-occupied homes, not just recent sales — at $118,400. Separately, Rock Island County's current median listing price (via Realtor.com data, 2026-06-01) runs $159,950. These cover different geography (city vs. county) and different measures (assessed value vs. active listings), which is why we show both rather than picking one — full source list on our data sources page.

Affordability Snapshot

Rock Island's Census-reported median home value works out to about 2.1x the area's median household income, and median gross rent runs roughly 17% of that same income on an annualized basis. Housing economists commonly flag a price-to-income ratio above 4x as historically elevated -- useful context, not a personal affordability verdict.
