We are pleased to present an opportunity to acquire a highly upgraded office building with Class A finishes. The Waters at Creekside presents investors with a rare opportunity to purchase a fully leased medical and professional office asset in one of Orange County's most accessible and established business environments. Located at 2900 Bristol Street, Building H, in Costa Mesa, California; the 12,457-square-foot, two-story office building offers stable in-place cash flow, a diversified tenant roster, and strategic freeway connectivity that supports long-term occupancy and tenant retention. The property generates annual gross rental income of $309,271, producing a Net Operating Income (NOI) of $225,947. Based on the current offering price, the asset is being offered at a 6.50 percent capitalization rate, providing investors with immediate yield from a stabilized income stream. The second floor provides a significant anchor tenancy and long-term demand driver. The ground floor features a diversified mix of professional and medical-related users, including financial services, insurance, psychology, and therapy tenants. This tenant composition reduces income concentration risk while creating a complementary service environment that supports occupancy stability. Situated within The Waters at Creekside office park, the property benefits from exceptional regional accessibility. The building is positioned immediately adjacent to the interchange of State Route 73 and State Route 55, providing direct access throughout Orange County and Southern California. The property's strategic location also offers convenient connections to Interstate 405 and Interstate 5 via State Route 55, making it highly accessible for employees, clients, and patients traveling from throughout the region. This investment opportunity is ideal for private investors, family offices, 1031 exchange buyers, and professional office investors seeking a stabilized, income-producing asset in Southern California's most established office markets.
