Brandywine Realty Trust is recapitalizing a large portion of its Northern Virginia office portfolio.

The Philadelphia-based REIT sold an 85% stake in eight Herndon office buildings totaling 1.3M SF to Boston-based Rockpoint Group for $312M, Brandywine said Wednesday in its Q3 earnings release.

The portfolio consists of four buildings in the Dulles Corner office park and four buildings in the Woodland Park complex, Brandwyine Senior Vice President Janet Davis tells Bisnow. The portfolio is composed of 2355 Dulles Corner Blvd., 2411 Dulles Corner Park, 13880 Dulles Corner Lane, 13825 Sunrise Valley Drive, 2121 and 2201 Cooperative Way, 2251 Corporate Park Drive and 2291 Wood Oak Drive.

Brandywine will retain a 15% ownership in the portfolio and will continue to manage and lease the buildings. It listed the portfolio for sale Sept. 30 and the buyer obtained mortgage financing to fund the transaction, the earnings release said.

The REIT's Northern Virginia holdings also include three office buildings in Fairfax, two in Falls Church, two in McLean and two in Vienna. In suburban Maryland, it owns three office buildings in Silver Spring, three in Rockville and one in Bethesda.

“We view Washington D.C. as a key market for us, and we will continue to seek opportunities to grow through select acquisitions of existing properties as well as development and redevelopment opportunities in urban or urbanized suburban markets that provide opportunities for sustained tenant demand and rent growth," Brandywine Senior Vice President John Norjen said in a statement.

The deal is the latest in a string of D.C.-area acquisitions for Rockpoint Group. The firm in March acquired Downtown D.C.'s Beacon Hotel for $60M. In April 2017, it bought the Shenandoah Building in Tysons for $55M, and in 2016 it bought Tysons' Westwood Metro Tower for $54M.

Brandywine announced the Northern Virginia deal alongside a major acquisition in Austin, Texas. Brandywine bought the remaining 50% interest from its partner on a 12-building portfolio totaling 1.6M SF, a deal that valued the portfolio at $537M.
