Early in his career, he was buying lots across the country and improving them on 40-year mortgages from the federal government at 5.5 percent interest. Those terms meant "we didn't have to put up much cash," he told Bender.

Not even Trump Tower was built with Trump's money. Chase Manhattan provided him with $24 million in financing to buy the leases, along with a $150 million construction loan.
"He can, thus, add another star to the honor badge of the venture capitalist:
