Move over Los Angeles. A 60,500-square-foot Florida mansion, called Le Palais Royal, is now on the market for $159 million which is $10 million higher than the asking price for Palazzo D’Amore, the Beverly Hills mansion which had been the most expensive listing in the United States, CNBC reports. However, Florida may not have the crown for long; a 74,000-square-foot house in Bel Air is under construction and is set to be priced at an astounding $500 million.
