Where does Realmo's Seabrook market data come from?
Realmo compiles Seabrook, NH figures from 6 recent recorded sales, 7 active sale listings, 23 active lease listings, 317 tracked off-market properties, the current Seabrook zoning release. Sale and lease figures refresh monthly; vacancy annually. Last updated 31 August 2026.
Methodology & data sources
- Asking prices and averages
- Computed from 7 active for-sale and 23 active for-lease listings in Seabrook, NH. 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: 6,194 zoned acres across 11 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 Northeast region level, retail vacancy is reported at Northeast region level, industrial vacancy is reported at Northeast region level and asking prices run materially above recent closed pricing.
- Coverage
- Metrics below the 10-observation threshold fall back one geographic level. The geography used is named on each figure.
