Where does Realmo's Barnwell market data come from?
Realmo compiles Barnwell, SC figures from 4 recent recorded sales, 64 active sale listings, 1 active lease listings, 424 tracked off-market properties, the current Barnwell zoning release. Sale and lease figures refresh monthly; vacancy annually. Last updated 31 August 2026.
Methodology & data sources
- Asking prices and averages
- Computed from 64 active for-sale and 1 active for-lease listings in Barnwell, SC. 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: 5,100 zoned acres across 12 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 South region level, retail vacancy is reported at South region level and industrial vacancy is reported at South region level.
- Coverage
- Metrics below the 10-observation threshold fall back one geographic level. The geography used is named on each figure.
