Dover, NHInc. 1623
Dover is the largest city in Strafford County and one of the oldest settlements in New Hampshire. The city's downtown along the Cocheco River has been revitalized, with restaurants, shops, and residential conversions in former mill buildings. The housing stock ranges from dense, multi-family neighborhoods near downtown to suburban single-family areas in the northern and western sections.
For property professionals, Dover is the most complex market in Strafford County — urban density downtown, suburban neighborhoods, commercial property along the highway corridors, and the Cocheco and Bellamy Rivers creating flood zone exposure. The city's growth and downtown revitalization have driven appreciation in the walkable neighborhoods.
