Methodology & data sources
- Asking prices and medians
- There are 5 active for-sale and 0 active for-lease listings in Newcastle, ME. The sale median is based on 5 of the for-sale listings that 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.
- 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: 20,885 zoned acres across 15 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 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, 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.
