"We want to take advantage of the appreciation that trophy properties have realized and redeploy this capital to mine opportunistic real estate investments for greater returns," says Eric Hadar, CEO of Allied Partners. Hadar and Robert Vahradian, president of Allied Partners, add that the company has earmarked $500 million in principal equity for investment in real estate.

The firm plans to focus on existing properties, real estate development and mezzanine lending here and other major metropolitan markets. The firm owns approximately two million sf of office, retail, multifamily and hotel properties primarily in the New York area. Its holdings include 568 Broadway, 95 Wall St., 50 West 40th St. and Woodbury Centre.
