The buyers are primarily users that plan to build buildings for their own purposes on the land, Harry E. Wardell, a vice president with locally based Lincoln Property Co., tells GlobeSt.com. Wardell and Steven J. Medwin, also a vice president with Lincoln Property represented CSX Transportation in all three sales.

"CSX has always sold their surplus land," Wardell says. These three pieces totaling 41.1 acres were the last three pieces of CSX's surplus land in South Florida and almost on the whole East Coast of Florida, he says.

Coparts Inc., which holds wrecked automobiles until insurance companies inspect them, purchased the biggest tract of land. The company bought 23.4 acres for nearly $2.3 million, which is about $97,998 per acre. The site is located in northwest Miami-Dade County, west of Northwest 36th Avenue between Northwest 107th Street and Northwest 119th Street. Michael Sigerman of Lucky Commercial Realty represented Coparts Inc.
