Bolton, MAInc. 1682
Bolton is a small, affluent, semi-rural town between Worcester and the Route 495 corridor. The town's landscape is defined by conservation land, orchards (including the well-known Bolton Orchards), and large-lot single-family homes. The Nashua River runs along the town's western boundary.
For property professionals, Bolton is a moderate-to-high-value residential market where lot size and rural setting are significant value components. The town's proximity to Route 495 and I-190 makes it commuter-accessible while maintaining a rural character.
