Methodology & data sources
Asking prices and medians
There are 3 active for-sale and 1 active for-lease listings in Colonia, NJ. The sale figure is the Middlesex County average, as too few listings here state a price per square foot; too few for-lease listings state a rent per square foot for a rent median. These are ASKING figures from live listings, not closed-transaction prices, and a figure resting on fewer than 10 listings says so where it is quoted.
Price per square foot
The county-level $/SF blends closed sales aggregated over the trailing months of available data, not a single day's snapshot — it can differ from any one month's own median.
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 October 2026 — not today — is the honest last update.
Known limitations
office vacancy is reported at Northeast region level, retail vacancy is reported at Northeast region level and industrial vacancy is reported at Northeast region level.
Coverage
Metrics below the 10-observation threshold fall back one geographic level. The geography used is named on each figure.
