Not entirely, but he is getting pressure from his lenders. One of his current projects is the Trump International Hotel & Tower in Chicago. It will be 92 stories which is the tallest building constructed since the Sears Tower was built in 1973. Usually Trump has several partners on his deals, but as this article explains, he went in this one solo.

So far, Mr. Trump has lined up buyers for a bit less than $600 million of condo units and condo-hotel units in a residential market that has virtually seized up. Yet he owes lenders as much as $1 billion when the loans are due, according to public records and several people familiar with the project. He has closed around $200 million in sales so far, with roughly $380 million still in contract. The retail portion of the giant building is for sale, at a time of rising vacancies for retail space in Chicago and one of the worst eras for retailers in years.
