Where does Realmo's Trenton market data come from?

Methodology & data sources
- Asking prices and averages
- Computed from 4 active for-sale and 0 active for-lease listings in Trenton, 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: 1,177 zoned acres across 9 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 and industrial vacancy is reported at Midwest region level.
- Coverage
- Metrics below the 10-observation threshold fall back one geographic level. The geography used is named on each figure.
