'Cash is still king' in Miami real estate

A very large percentage of wealthy Miami home buyers are from overseas, and a huge portion of those foreign buyers pay for their homes in cash, according to one realtor from the area.

Speaking of her own experience with high-end buyers, Patricia Delinois, CEO of Century 21 Premier Elite Realty, said that "62 percent of the buyers are from overseas, and 90 percent of those buyers are purchasing homes in cash."

Delinois, told CNBC's "Power House" that said "cash is king" among buyers who hail largely from Brazil, Venezuela, Argentina, Canada, France, Colombia, Mexico and Peru. (Delinois made no mention of Russian buyers, who have been prominent in the market in recent years.)
