Methodology & data sources
- Asking prices and medians
- There are 9 active for-sale and 3 active for-lease listings in Delaware City, DE. The sale median is based on 4 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.
- 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 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.
