5151 N Harlem Avenue offers a rare value-add investment opportunity within Chicago’s high-demand Northwest Side office market. This 12,596-square-foot, three-story property is prominently located at the signalized intersection of N Harlem Avenue and W Foster Avenue in a corridor with strong traffic exposure of approximately 36,200 vehicles per day. The building is currently 61% occupied by a diverse tenant roster across financial, professional, and service uses, providing stable in-place income with upside potential through lease-up of the remaining approximately 4,896 square feet. Tenants benefit from exceptional accessibility, including proximity to the Harlem CTA Blue Line station, direct access to I-90, and quick connectivity to O’Hare International Airport. The surrounding area features a strong mix of national and local retailers such as Target, Kohl’s, Best Buy, Dick’s Sporting Goods, Marshalls, Nordstrom Rack, and multiple restaurants. Investors have the opportunity to capitalize on market fundamentals, including limited supply and long-term demand for well-located office assets. Flexible lease structures further enhance owner-user potential, creating a compelling investment for both stabilization and future appreciation.
