John Marshall II boasts a coveted Tysons Corner submarket location within easy access to such major thoroughfares as the Capital Beltway, the Dulles Toll Road and Interstate 66. Built in 1996, the nine-story structure on Greensboro Drive has a current assessed value of about $39 million, according to Fairfax County records. In addition to its class A office attributes, the property offers parking accommodations via a seven-level parking facility it shares with a neighboring office building. John Marshall II proved a great draw for a slew of hopeful investors.

"Not only does the sale speak to the excellent health of the Washington, DC office market," notes Cousins president and CEO Tom Bell, "it also recognizes the quality of the building and the quality of a customer like Booz Allen Hamilton."

For Cousins, the sale of John Marshall II marks the seventh office disposition this year. The timing was right for the company to let go of the asset. "Looking at the properties we own and those we own with other companies, and the prices we were being offered, we thought that we were seeing values that we probably won't see for a very long time," Matt Gove, Cousins director of corporate communications, tells GlobeSt.com. "We felt we owed it to our shareholders to capture the value that we've created in these projects while the market is still good."
