What's special

A rare turnkey 2-family with lots of options! Move into one unit and have the tenant subsidize some of your mortgage, rent out both, or tear down and rebuild. Potential to build 2 side-by-side townhomes on the existing lot (buyer to do all due diligence). The larger units feature hardwood floors, a renovated eat-in kitchen, an updated bathroom, and split air conditioning/heating units. The smaller unit features hardwood floors, a smaller eat-in kitchen, a cozy bathroom, and a separate entrance. Separate driveways allow for autonomy for each unit. Flat lot with frontage on both streets. Easy access to rt 128/95, bus 61, proximity to Lazazzero Playground and Hardy Pond, MacArthur Elementary School, and the newly built state-of-the-art Waltham High School.
