The Emmett House -- Historic Charm, Rare Scale & Exceptional Potential! A once-in-a-lifetime opportunity to own one of Belmont's most distinctive historic properties. This beautifully preserved landmark 2-story duplex dates back to the late 1800s & showcases timeless architectural character with a historically significant exterior facade reflecting early Belmont's charm & heritage. Set on an expansive approx. 17,774 sq.ft. lot, the property features 2 spacious units, each with 3 beds & 2 baths, totaling approx. 3,023 sq.ft. This square footage does not include the approx. 600 sq ft detached two-car garage with additional storage, which provides valuable parking, functionality, and flexibility. This rare configuration offers options for owner-users, extended family, rental income, or long-term investment. The property may offer future value-add potential, including possible interior modifications to create up to 4 units plus ADU potential, subject to buyer investigation & city approvals.
