About this home

Charming, beautifully remodeled 3-bedroom, 1-bath home offering 1,035 square feet of comfortable living space, plus a detached 250-square-foot cottage (ADU). The rental income from the cottage provides an excellent opportunity to offset your mortgage, making it easier to own more home in this desirable, quiet court location. Tasteful updates are found throughout the property. Gorgeous hardwood floors flow through most of the home, complemented by tile flooring in the kitchen, bathroom, and laundry room, with carpet in select areas. The updated kitchen features Corian countertops, attractive wood cabinetry, a 4-burner gas range, built-in microwave, and abundant cabinet space. A spacious laundry room offers even more storage with extensive built-in cabinetry. The inviting living room showcases a custom tray ceiling, elegant crown molding, and energy-efficient LED lighting, creating a warm and welcoming atmosphere. Step outside to a patio deck overlooking the private, fenced backyard with lush lawn—perfect for relaxing or entertaining. A matching storage shed provides additional space for tools, gardening equipment, or seasonal items. A standout feature of this property is the detached, updated studio ADU, offering exceptional flexibility and income potential. Currently rented for $1,750 per month plus utilities, the cottage is separately fenced for added privacy and is ideal as a rental, guest house, private home office, or space for extended family. Move-in ready and thoughtfully updated, this exceptional property combines comfort, style, and outstanding investment potential. Don't miss this rare opportunity!
