The price of Brickell dirt keeps rising, even for land tied up in bankruptcy cases.

U.S. Bankruptcy Judge Laurel M. Isicoff in Miami on Tuesday approved the $21.5 million sale of Miami developer Renzo Renzi’s Brickell-area land to Watson Investigations LLC. The Coral Gables company has until July 30 to close on the acquisition of the 33,927-square-foot site at the corner of Southeast Eighth Street and First Avenue.
