Medfield, MAInc. 1649
Medfield is a suburban town southwest of Boston with a well-defined town center and residential neighborhoods that have developed primarily since the mid-20th century. The former Medfield State Hospital — a large institutional campus that closed in 2003 — is the town's most significant redevelopment opportunity, and its future use will meaningfully affect the local property market.
For property professionals, Medfield is an established suburban market with strong schools, single-family-dominant housing, and assessed values in the upper-moderate range for the region. The state hospital site adds a dimension of uncertainty and opportunity that most comparable suburban communities don't have.
