Southborough is an affluent town along the Massachusetts Turnpike and Route 9, positioned between the MetroWest communities and Worcester. The town is home to several private schools — St. Mark's School, Fay School, and the New England Center for Children — which create institutional land use and contribute to the town's educational reputation. The housing stock is predominantly single-family homes on generous lots.
For property professionals, Southborough is an upper-value residential market where schools, highway access, and lot size drive demand. The town's position on the Mass Pike makes it accessible to both the Route 128 and Worcester employment markets.
