Overview

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.

Pre-existing termite damage in the basement. The seller has monitored it as advised by the previous seller—no known new activity since purchase. Roof is thought to be at least 20 years old.
