By the 1970s, many of those Harlemites who were able to escape from poverty left the neighborhood in search of better schools and homes, and safer streets. Those who remained were the poorest and least skilled, with the fewest opportunities for success. Though the federal government's Model Cities Program spent $100 million on job training, health care, education, public safety, sanitation, housing, and other projects over a ten-year period, Harlem showed no improvement. The city began auctioning its enormous portfolio of Harlem properties to the public in 1985. This was intended to improve the community by placing property in the hands of people who would live in them and maintain them. In many cases, the city would even pay to completely renovate a property before selling it (by lottery) below market value.
