Walpole, MAInc. 1659
Walpole is a suburban town south of Boston with a well-defined town center and residential neighborhoods that have grown through successive waves of development. The town is also home to MCI-Cedar Junction (formerly MCI-Walpole), the state's maximum-security prison, which occupies a significant parcel and creates a unique land-use dynamic. The residential areas are predominantly single-family homes with moderate to generous lot sizes.
For property professionals, Walpole is a solid suburban market with good schools, commuter rail access, and a housing stock that spans enough eras to create meaningful variation in building condition. The prison's presence is a local reality that affects some nearby property values but does not define the broader market.
