ALEXANDRIA, VA-The Mark Winkler Co. residential portfolio has just been sold off in three separate transactions valued at an aggregate $900 million. Consisting of 12 nearly fully leased apartment properties, the portfolio features more than 5,000 units located in various areas of Northern Virginia.

The JBG Cos. walks away with the bulk of the portfolio, taking 10 of the properties. With the disposition of its multifamily assets, Winkler bows out of the real estate market; the company already sold off its office and retail holdings. The multifaceted disposition was orchestrated on behalf of Winkler by Bill Roohan, Andy Boyer, Mike Muldowney, John Sheridan, and Jonathan Greenberg of real estate services firm CB Richard Ellis.

JBG spent $780 million for 10 of the apartment communities. The company has closed on the purchase of nine of the properties, which account for a total of 3,726 units, and expects to close on the final transaction in May. JBG's new purchases include Alexandria's Alexandria-Millbrook at Mark Center, Lynnbrook at Mark Center, MeadowCreek at Mark Center, Willow Run and Brookdale at Mark Center. Also included are Stoneridge at Mark Center, Hillwood at Mark Center, Annandale's Fairmont Gardens, Reston's Fairway Apartments and Arlington's Dominion Towers.
