Methodology & data sources
- Asking prices and averages
- Computed from 23 active for-sale and 0 active for-lease listings in Caseyville, IL. These are ASKING figures from live listings, not closed-transaction prices, and a segment carried by a handful of listings reads as indicative rather than an average.
- Vacancy rates
- Published per-sector market series, taken at the metro level where one exists and otherwise at the Census-region level — a chart reading "in <region> region" is a regional number, not this city's.
- Zoning and land use
- The current municipal zoning release: 4,971 zoned acres across 10 districts. Shares are of zoned land, so parcels the release leaves unclassified are excluded from the mix.
- Refresh
- The monthly aggregates close at the end of the previous month, so 31 August 2026 — not today — is the honest last update.
- Known limitations
- office vacancy is reported at Midwest region level, retail vacancy is reported at Midwest region level, industrial vacancy is reported at Midwest region level and asking prices run materially above recent closed pricing.
- Coverage
- Metrics below the 10-observation threshold fall back one geographic level. The geography used is named on each figure.
