In the case of the Vegas tower, he promised investors he would develop two towers but failed to secure enough buyer commitments for more than one. He also failed to close on enough units in the tower that did get built, and was forced to sell hundreds of units at a loss to a timeshare company in order not to default on yet another loan.
