The newly listed Unit A4 at 22 Branchfield Street in Dorchester’s Lower Mills section offers that rarest of properties in Boston: a decent condo for under $200,000. Better yet, it’s not a studio! Better yet, the 562-square-foot spread is a genuine 1-BR rather than a studio or a studio with conversion possibilities. It has an open living room and dining room, and there’s laundry in the building. The condo last sold for $154,000 in August 2015 and is now asking $195,000 through Re/Max Destiny.
