Finance of America Mortgage, a Blackstone Company, has signed a lease for 9,000 square-feet of space on the second floor of Rivulon’s newly completed 125,000-square-foot, four-story office building in Gilbert.

Thomas Title & Escrow also signed a lease for 4,000 square-feet of space in the building.

Rivulon is a 250-acre mixed-use development near Gilbert Road and Loop 202 that broke ground in late 2014.

Brian Ellis, president and chief operating officer of Nationwide Realty Investors, which is the Ohio-based group behind the development, said the announcement “is reflective of Rivulon’s strong momentum and Gilbert’s great market.”

Gilbert’s first Mercedes-Benz dealership is set to open at Rivulon in the summer.

The $750 million business district will include 3 million square-feet of office space and 500,000 square-feet for retail and hospitality.
