Stay classy

Guatemalan entrepreneur and onetime politician Harold Caballeros learned one of his biggest lessons in commercial real estate in the late 1990s real estate boom in Miami: the art of the hyper-focus.

Caballeros, earning his M.B.A. at the University of Miami, was swept up in the buying frenzy, particularly in condos and apartments. With opportunities all over, Caballeros zeroed in on a small strip of Brickell Avenue, in the financial hub of downtown Miami.

In a few months, he and some business partners bought and flipped more than 40 units, apartments and condos, for a solid profit. “I got to know every price, every listing and every square foot,” Caballeros says. “Working only on Brickell worked out well for me.”
