Welcome to Summer Lake, one of Oakley's most sought-after communities. This spacious 5-bedroom, 4 full bathroom home is thoughtfully laid out - with a downstairs bedroom and full bath perfect for guests or multigenerational living. The open-concept kitchen flows directly into the family room, anchored by granite countertops, stainless steel appliances, and hand-scraped hardwood floors and plantation shutters add a clean, custom finish. A separate dining space gives you flexibility for special occasions, and the upstairs loft creates the perfect bonus space for a playroom, home office, or second hangout zone. Step outside to a low-maintenance backyard designed for enjoyment - covered patio, built-in fire pit, turf, and a dog run. Private, quite and no rear neighbors. Three-car garage. Close distance to Summer Lake Elementary, the community pool, clubhouse, lake, parks, and trails.
