As Real Estate Market Turns, Donald Trump's Billions Lose Their "4-Handle"

``FORBES' new investigation into Trump's wealth pegs his fortune at $3.7 billion, down $800 million from a year ago. A softening of New York City's real estate market, particularly in retail and office, where valuations are trending down, has diminished his estimated net worth. New information was also a factor. Of the 28 assets or asset classes scrutinized by FORBES, 18 declined in value, including his trademark Trump Tower on Manhattan's Fifth Avenue, his downtown jewel 40 Wall Street and Mar-a-Lago, his private beachfront club in Palm Beach.''
