Daniel M. Blanco, executive vice president and director of leasing for Broad Street, represented the ownership, while Louis D'Avanzo, Nate Pennington and Christina Coppetelli of Cushman & Wakefield negotiated for the tenant. Financials details of the transaction were not released, but space on that floor is advertised at $30 per sf.

"The tenant wanted to stay in its current location, but needed to expand its existing space to handle the increased enrollment at this facility," says Blanco. Broad Street's in-house team build out of the expansion space, while still enabling Kaplan to maintain day-to-day business in its existing space.

Built in 1916, 61 Broadway is now more than 85% occupied. The tower is home to investment firm Ingalls & Snyder LLC, American Lung Association and international law firm Healy & Baillie. Broad Street Development is an owner and management group led by Raymond Chalmé.
