Wilmington, MAInc. 1665
Wilmington is a suburban town along I-93 and Route 129, positioned between the Route 128 corridor and the Merrimack Valley. The town developed primarily as a post-war suburb, and the housing stock is dominated by single-family ranches, capes, and colonials from the 1950s through 1980s. Commercial corridors along Main Street and Route 129 bring retail and office properties to the mix, and the I-93 interchange has attracted additional commercial development.
For property professionals, Wilmington is a solid middle-market suburb with consistent housing stock, moderate assessed values, and the kind of commercial property base that comes with highway interchange proximity. The town's position makes it accessible to both the Route 128 and Merrimack Valley employment markets.
