Tucked away at the end of a quiet cul-de-sac in one of Costa Mesa's most sought-after Back Bay enclaves, 2342 Cynthia Court presents a rare opportunity to own a custom single-family residence in a location where demand continues to rise and opportunities remain incredibly limited. Positioned on the highly desirable Back Bay side of Costa Mesa - away from freeway influence - this home offers an exceptional blend of privacy, lifestyle, and long-term upside just moments from everything that defines Newport Beach and coastal Orange County living. Unlike many nearby properties, this is not a PUD and there are no HOA dues, offering the privacy, ownership experience, and flexibility today's buyers are increasingly searching for - and rarely finding this close to the coast. From the gated courtyard entry and tranquil fountain, to the rich stonework, custom millwork, crown molding, and expansive living spaces, the home carries a sense of warmth, quality, and timeless character from the moment you arrive. Thoughtfully designed throughout, the residence blends comfort and functionality with inviting spaces ideal for both everyday living and entertaining. At the heart of the home is a chef-inspired kitchen featuring premium Viking appliances, custom cabinetry and paneled appliances, farmhouse sink, stone counters, and generous entertaining space designed for intimate evenings and larger gatherings alike. Natural light pours throughout the home and flows seamlessly into a private backyard retreat complete with low-maintenance turf, spa, and mature lemon tree. The spacious primary suite offers a true retreat, featuring a large walk-in closet, cozy double-sided fireplace, and spa-inspired ensuite with skylights, soaking tub, oversized walk-in shower, dual vanities, and custom finishes throughout. Situated walking distance to the Back Bay trails and nature preserve, and only minutes from Newport Beach, Lido Marina Village, 17th Street, award-winning dining, shopping, top-rated schools, and the beach, this is the type of neighborhood buyers wait years to break into. The Back Bay pocket of Costa Mesa continues to see tremendous pride of ownership, transformation, and demand, making cul-de-sac opportunities like this increasingly rare as buyers continue seeking coastal property with long-term upside near the ocean.
