Completely unexpected! This charming Mansard-style single family, tucked back off of Tremont Street, is a joyful surprise. The bright blue exterior & gardens, lovingly redone by the current owners, give the home an almost storybook feel and create a sweet oasis in the heart of Inman Square. Inside, the house is just as cheerful, with high ceilings, wonderful natural light, loads of character and a flexible 2/3 bedroom layout that feels both comfortable and full of possibility. The current owners have made thoughtful improvements, adding significantly to both its livability & move-in readiness. The kitchen was reconfigured & upgraded with all new appliances, a second-floor laundry room was created and a brand-new washer & dryer installed, the entire interior was repainted & new blinds were installed. Behind the scenes, equally important improvements include a new French drain, sump pump, dry well, radon mitigation system and new support beams in the basement. Finally, where what was once almost entirely asphalt has been replaced with a garden & green-paver driveway, completely changing the feel of the property. This is a truly special home, and just a 7-minute walk to the Union Square T stop!
ADU Potential

Based on listing data, which indicates the property type — not the zoning district. Local dimensional, septic (Title 5), and historic-district requirements still apply. Not legal advice — verify with the municipality.
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 MLS and other third-party data may be inaccurate or out of date.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.
