Bright and versatile, this move-in ready 3+ bedroom, 4-bath home with a 2-car garage is located in Castro Valley’s award-winning school district! The main level offers three bedrooms and two full baths, along with hardwood flooring and an open, airy living space filled with natural light. The kitchen features stainless steel appliances and plenty of counter space, making it ideal for cooking and entertaining. The spacious DOWNSTAIRS BONUS AREA includes a full bath and a wet bar with cooktop wiring already in place, making it easy to convert into a kitchenette. This versatile bonus area offers potential for an in-law suite, office, or game room, providing great flexibility for a variety of needs (buyer to verify possible uses). Out back, enjoy low-maintenance composite decking, a private setting, and an in-ground pool, plus a pool house with its own full bath. Prefer no pool?

Ideally located less than two miles from BART—a commuter’s dream—and close to hiking trails, the golf course, and vibrant downtown Castro Valley. This is a must-see home you won’t want to miss!
