Welcome to 507 Summer Street, a property that offers the perfect blend of comfort, flexibility, and future potential. Tucked away at the end of a quiet dead-end street, this 4-bedroom, 2-bath home has a warm, welcoming feel from the moment you arrive. The owner's unit has been thoughtfully renovated, creating a move-in-ready space that feels bright, comfortable, and truly like home. Each unit is equipped with its own forced hot air heating system for added convenience and efficiency. One of the property's standout features is the walk-out basement, complete with two separate exits and an existing heating system. Whether you're looking for additional living space, a workshop, storage, or exploring the possibility of creating a one-bedroom accessory dwelling unit (ADU), this lower level offers incredible flexibility. Outside, you'll appreciate the detached garage, ample off-street parking, and a rare bonus-an additional lot located in Blackstone, MA that may offer future building potential (buyers to perform their own due diligence). Whether you're searching for a place to call home with room to grow or a property with long-term upside, 507 Summer Street offers a unique opportunity in a peaceful setting with possibilities that are hard to find.
