In yet another sign that times are tougher for Plantation foreclosure attorney David Stern, he is looking to unload luxury assets worth tens of millions, including two estate properties on Hillsboro Beach that stretch from the Intracoastal to the blue waters of the Atlantic and what is believed to be his Italian-built superyacht. Stern, 50, made a fortune by building Florida's largest foreclosure legal practice, with an army of attorneys and more than 1,000 employees processing paperwork for repossessions throughout the state. He received a $58.5-million payout last January when he took his paperwork operation public and the new company, DJSP Enterprises, began trading on the Nasdaq stock exchange. He collected expensive properties, Ferraris and other luxury cars, and two jets.
