Frequently Asked Questions

Where does Realmo's Ontario market data come from?
Realmo compiles Ontario, WI figures from 2 recent recorded sales, 16 active sale listings, 44 tracked off-market properties. Sale and lease figures refresh monthly; vacancy annually. Last updated 31 August 2026.
Methodology & data sources
Asking prices and averages
Computed from 16 active for-sale and 0 active for-lease listings in Ontario, WI. 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.
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.
