1827
Historic Thaddeus Frost House (c. 1827), a rare Federal-style Colonial prominently sited on a picturesque 12,486 sq ft corner lot in the sought-after Winn Brook area near Belmont Center. Rich in period detail and architectural character, this distinctive property features wide pine floors, original millwork, built-ins, and multiple fireplaces. A unique opportunity for contractors, developers, restoration specialists, or buyers seeking a significant restoration project or the opportunity to build a new home in a premier Belmont location. Convenient to Belmont Center, Route 2, public transportation, Cambridge, Boston, and Winn Brook Elementary School.Property requires extensive structural rehabilitation and is being sold strictly as-is. Significant termite damage exists to main beams, sills, and numerous joists; the foundation also requires substantial restoration. Visible knob-and-tube wiring is present, and the house will require rewiring. The home is not connected to town sewer; the Town has no records regarding a septic system or cesspool. The Thaddeus Frost House is listed on the Town and Massachusetts Registry of Historic Homes and is located within its own Historic District. EXTERIOR RENOVATIONS,ADDITIONS, OR DEMOLITION TO BUILD A NEW HOME, require a Certificate of Appropriateness (COA) from the Belmont Historic Commission. The Commission may enact a one-year demolition delay. Any construction of a new home, including its exterior design, would require approval and a Certificate of Appropriateness under applicable Historic District regulations.

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 MLS and other third-party data may be inaccurate or out of date.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.
