A full bedroom and bathroom on the first floor provide a convenient option for guests, extended family, or a home office. Upstairs, the spacious loft offers even more flexibility and could easily be used as a playroom, office, media room, or converted into a fifth bedroom. The primary suite is a relaxing retreat with a spa like bathroom featuring a frameless glass shower, soaking tub, dual vanities, and a large walk-in closet. Two additional bedrooms, a laundry room, and plenty of storage complete the second floor. The fully fenced backyard is designed for easy maintenance, with pavers and drip irrigation creating a comfortable space for relaxing, entertaining, or enjoying evenings outdoors. The home also includes upgraded flooring throughout the main level, Lutron smart lighting, and an additional deeded parking space directly in front of the property that can accommodate a larger vehicle.
