BOULDER – A Dallas investment firm recently chalked up a 38 percent return on its 2014 purchase of a building aerospace giant Lockheed Martin leases in Gunbarrel.

Macfarlan Capital Partners closed on the sale of the property at 6304 Spine Road at the end of last month for $18.45 million. The buyer was a New York-based entity called Maia Boulder LLC.

Macfarlan bought the office building in July 2014 for $13.4 million.

Bethesda, Md.-based Lockheed Martin (NYSE: LMT) leases the entire 171,000-square-foot building, where the company employs roughly 450 people who support Lockheed’s Space Systems business.

Lockheed recently had signed a five-year lease extension with Macfarlan prior to the building sale.

Maia Boulder LLC, according to Colorado Secretary of State records, shows a primary address that corresponds to New York investment firm Empire Square Group, though officials for the company could not be reached for comment.
