Exceptional opportunity to own two well maintained buildings on a single deeded lot in Biddeford. 18 Congress Street, a separate two-unit building consisting of two 2-bedroom, 1-bath apartments. The property has seen significant updates, including a newer Biasi boiler (approximately five years old) and a new roof installed in July 2025. The primary residence at 19 Free Street is a raised ranch offering comfortable living space along with an impressive heated four-car attached garage. While some interior finishes may offer opportunities for cosmetic updates, the home has been thoughtfully maintained and features a newer Biasi boiler, heat pumps installed approximately five years ago in the primary and second bedrooms, hardwood flooring in the living room, central vacuum system, and a whole-house propane-powered Siemens generator for added peace of mind. The grounds are enhanced by beautifully landscaped gardens, a storage shed with its own electrical subpanel, and ample outdoor space to enjoy. POSSIBLE Additional LOT for an ADU or small home. Whether you're seeking owner-occupied flexibility, rental income potential, multi-generational living arrangements, or an investment opportunity, this unique property offers a variety of possibilities in a convenient Biddeford location. Rarely does a property with two residential buildings on one lot become available with this combination of space, utility, and income-producing potential.
