NEW YORK CITY-A mixed-use property across from Atlantic Yards has secured its largest lease to-date. The Human Resources Administration of New York (HRA) signed a 20-year lease for 400,000 square feet inside the 10-story, 660,000-square-foot building at 470 Vanderbilt Ave. in Downtown Brooklyn, says landlord GFI Development Co., the development arm of GFI Capital Resources Group.

The organization will consolidate three of its Brooklyn offices into the space, says GFI. The new offices will house job training programs and other services provided by some 1,800 employees. Construction will begin toward the end of the year, with move-in targeted for winter 2012-13.

The deal involved a variety of parties and lenders, and will be financed through a recapitalization led by investment firm Starwood Capital Group LP, involving $30 million of equity, a $130-million senior loan by CIBC and $44 million of tenants improvement financing arranged by Lance Capital LLC and CGA Capital Corp.
