South Florida faces a growing affordability problem as housing demand outstrips supply, according to Ana-Marie Codina, whose family firm develops master-planned communities in the region.

“We definitely need more supply,” Codina said in an interview at a Bloomberg New Voices event in Miami on Friday. “There’s very little differential between what rents we’re getting versus some of our competitors who have older product or less amenitized product. And that’s a function of supply.”
