NEW YORK CITY-In continuing its Manhattan acquisition spree, publicly-traded multifamily REIT UDR, Inc. completed its acquisition of the 14-story, 210-unit 21 Chelsea luxury apartment building from owner 21 Chelsea LLC for $138 million on Friday morning. The transaction is the latest deal to close in UDR’s current credit facility, which also includes the 706-unit, 35-story Rivergate apartment tower in Murray Hill and the 185-unit View 14 in Washington DC. In total, the three communities were acquired for $687 million.

Tom Toomey, president and CEO of UDR, says the latest acquisitions are all part of the company’s new Northeast strategy. “It continues our portfolio transformation of owning apartment homes in markets characterized by above average job growth, low home affordability and limited new supply, three of the key drivers to strong rental growth,” Toomey says, in an earnings report. The company now plans to redevelop all three of the buildings with new improvements and amenities.
