A rare opportunity to own a spacious home in the heart of Gorham with exceptional flexibility and built-in income potential. The main residence at 164 Main Street offers approximately 3,118 square feet of finished living space over two floors, with 4/5 bedrooms, 2 full baths, and an attached 2-car garage. Thoughtfully maintained by the current owners, who have lived and worked here for approximately 30 years, the home offers generous living space in a convenient location near Gorham's walkable downtown, local businesses, restaurants, services, and area amenities. What truly sets this property apart are the additional spaces that complement the main residence. Above the garage is an approximately 644-square-foot one-bedroom apartment, currently rented, providing an opportunity for supplemental income or potential future use for extended family, guests, or other needs. At the rear of the property is approximately 826 square feet of finished professional office space, also currently leased. The office includes a waiting area, office/exam rooms, storage, a bathroom, ADA access, and dedicated parking, allowing the property to provide additional income without sacrificing the primary residential living space. Currently zoned Office Residential, the property's size and configuration may also offer possibilities for additional development, expanded units, a possible backlot, or other future uses, subject to applicable zoning, municipal approvals, and buyer due diligence. Whether you're looking for a substantial primary residence, additional rental income, space for future flexibility, or a property with longer-term possibilities, 164 Main Street offers a combination that is difficult to find in Gorham.
