Dover, MAInc. 1635
Dover is one of the most affluent and rural towns in the Boston metro area — a community of estates, horse farms, and wooded parcels that has maintained its low-density character through large-lot zoning and conservation easements. The town has no commercial district, no traffic lights, and a housing stock that consists almost entirely of large single-family homes on multi-acre parcels.
For property professionals, Dover is a rarified market where individual properties are assessed in the millions and where the estate-like character means every property is unique. Private wells, private septic, limited fire hydrant coverage, and long driveways are the norm. The town's proximity to Wellesley, Needham, and the Route 128 corridor keeps demand strong among executives and professionals seeking space and privacy.

Insurance & Underwriting
