Developers and investors looking to get their foot into growing downtown Miami have two opportunities with a $40 million portfolio and the final Miami Worldcenter site hitting the market.

The noncontiguous, five-building portfolio comprises older two-story retail buildings totaling 72,517 square feet on less than an acre in the Central Business District.

Zoning allows construction of up to 80 stories on the lots, although taller building proposals would be an option requiring city and Federal Aviation Administration approval.
