Trump began his career at his father's real estate company, Elizabeth Trump & Son. He later renamed the company The Trump Organization, which has its headquarters at 40 Wall Street. The company focused on middle-class rental housing in Brooklyn, Queens, and Staten Island. One of Trump's first projects, while he was still in college, was the revitalization of the foreclosed Swifton Village apartment complex in Cincinnati, Ohio. His father had purchased it for $5.7 million in 1962. Trump became closely involved in the project. With a $500,000 investment, he turned the 1200-unit complex with a 66 percent vacancy rate to 100 percent occupancy within two years. In 1972, the Trump Organization sold Swifton Village for $6 million.
