New Castle County occupies the northern end of Delaware, bounded on the east by the Delaware River and cut across by the Chesapeake and Delaware Canal. Its age-restricted communities sit largely in the suburbs around Wilmington and in the areas south of the canal near Middletown, with I-95, US 13 and US 40 providing access. This search includes both houses and condos in those communities. Active Adults Realty works statewide and understands how northern Delaware's active adult neighborhoods differ from the coastal ones.
