DALLAS-One of the city’s prominent high-rises has a new ownership, as well as a new leasing and management agent. Cornerstone Advisers acquired the 20-story Northpark Central and hired Transwestern to handle leasing and management for the 491,803-square-foot office building.

Cornerstone purchased the class A property from a fund sponsored by Apollo Real Estate Group for an undisclosed amount. Local experts estimate the asset, located at 8750 N. Central Expressway, sold for more than $50 million.

With the acquisition, Cornerstone now owns three office properties in the Metroplex including Waterway Tower in the Las Colinas submarket and Three Forest Plaza in the Park Central submarket. Transwestern handles the leasing and management for all three properties, according to Matt Hurlbut in Transwestern’s local office. He and Fletcher Cordell will head up the leasing team, while Susanne Doublin and Nicole Sladovnik will manage the property.
