Frequently Asked Questions
Where does Realmo's Saint John market data come from?
Realmo compiles Saint John, IN figures from 14 active sale listings, 4 active lease listings, 252 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 14 active for-sale and 4 active for-lease listings in Saint John, IN. 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.
