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.
Estimates — not financial advice
These figures are illustrative estimates for informational purposes only — not an appraisal, valuation, or guarantee of rent, income, or returns, and not financial, tax, or investment advice. Rent is either the figure reported on the MLS listing — in-place rent that may differ from market and is not verified against the actual leases — or, where the listing reports none, an estimate from HUD Small Area Fair Market Rents, a government benchmark that may differ from actual market rent. Each figure is labelled with its source. Cap rate, NOI, and returns depend on the assumptions shown, which you can change. MLS and other third-party data may be inaccurate or out of date. Verify all figures independently and consult your own financial, tax, and legal advisors before making any investment decision.
