Florida cities are still among the nation's top metro areas in the share of "underwater" homes in their communities.

A list compiled by the research firm RealtyTrac puts four Florida cities among the top housing markets with seriously 'underwater' homes at the end of last year.

At the top of the list is Las Vegas, but the Nevada gambling mecca is followed by Orlando, Tampa, Jacksonville, Cleveland, Miami, Detroit and Chicago.

Roughly a quarter of the homes in the Florida cities are underwater, a situation in which the loan on a home is greater than the worth of the property.
