About this home

Incredible opportunity to own a magnificent expanded ranch perfectly situated mid-block on a flat, usable lot with endless potential. This house needs TLC. This sprawling 3- to 4-bedroom home offers a versatile layout, starting with an oversized blacktop horseshoe driveway leading to an attached garage. The exterior boasts beautiful vinyl siding with a partial brick skirt and custom brick planters, while the front of the home is finished in elegant cedar impression siding. Inside, you’re welcomed by an open floor plan featuring hardwood floors, a formal living room drenched in natural light, and a chef’s kitchen outfitted with oak cabinetry and ample counter space. The main level includes three spacious bedrooms and a full bathroom, plus an additional private wing that offers a potential fourth bedroom with its own full bath—ideal for extended family. A full finished basement with high ceilings, outside entrance, and space for a possible second kitchen (with proper permits) expands the opportunity even further. The backyard includes a wooden deck that needs some TLC, a two-car carport, and plenty of space to create your dream outdoor oasis. Home is being sold as is, making this the perfect chance to customize, invest, or make your move-in vision a reality.
