While formally founded in 1983, Key Properties maintains roots dating back to 1952 when Abraham Schlussel launched his construction business. Beginning in the 1970s and through the following decade, he expanded into real estate investment as a private owner and joint venture partner. His sons, Marc and David, joined the company in the mid-1980s as co-managing partners, and have continued to guide and expand the company’s portfolio. In 2017, David’s son, Jonathan, joined Key Properties – marking the involvement of a third generation of Schlussels. Key Properties invests in a diverse range of commercial property types – with a focus on value-added potential – and is a leading expert in Brownfields redevelopment and condemnation proceedings.

The company was named a 2017 “New Jersey Family Business of the Year” honoree by Fairleigh Dickinson University’s Rothman Institute of Innovation and Entrepreneurship, for its contributions to the economy and community.
