Nestled in the heart of Lafayette, a premier East Bay community renowned for its exceptional quality of life, natural beauty, and family-friendly atmosphere, 3615 Chestnut Street represents a rare multifamily investment opportunity. In a market where multi-family properties seldom become available—comprising only a small fraction of the housing stock amid a predominance of single-family homes—this twin-style duplex, constructed in 2014, offers a compelling option for investors or owner-occupants seeking stability and potential in one of California's most desirable suburbs. Spanning approximately 2,053 square feet on a 4,800-square-foot lot, this two-story property features two well-designed units, each with an open-layout 2-bedroom, 2.5-bathroom configuration ideal for modern living. Highlights include luxury vinyl plank flooring, stainless steel kitchen appliances, custom finishes, and a paver driveway leading to ample parking with a one-car garage suitable for vehicles or storage. The site also holds potential for adding 1-2 accessory dwelling units (ADUs), providing avenues for future expansion in a community committed to sustainability and thoughtful growth. The property's prime location enhances its appeal, with a Walk Score of 92/100 placing it within easy reach of downtown Lafayette's shops, dining, and amenities. Residents enjoy convenient access to the Lafayette BART station for seamless commutes to San Francisco and beyond, three nearby shopping centers just a 7-minute walk away, major freeways, and scenic trails in Mount Diablo State Park. Families are drawn to the area for its top-rated schools in the Lafayette Elementary School District and Acalanes Union High School District, including highly regarded institutions like Lafayette Elementary, Burton Valley Elementary, and Acalanes High School, which consistently earn accolades for academic excellence. Currently fully occupied and income-producing, the property generates steady revenue with Unit 1 leased at $3,700 per month through November 30, 2025, and Unit 2 at $3,750 per month through May 31, 2026. In Lafayette's stable and sought-after rental market, supported by low crime rates, clean air, and a vibrant small-town vibe, 3615 Chestnut Street stands as an exceptional asset poised for long-term value. Additionally, the adjacent property at 3621 Chestnut Street—a three-unit multifamily residence with a duplex and detached ADU—is also available for purchase, presenting a unique chance to acquire both side-by-side parcels for expanded investment potential.
