The government is still doing this right now:
Denise Tejada bought a house last month at the age of 20, thanks in large part to a loan guaranteed by the Federal Housing Authority. This story offers a dramatic demonstration that, despite the housing bubble causing the worst economic downturn in generations, the ideology of home ownership is alive and well in the United States and still being supported by the government.
Without question, Tejada's loan is toxic--to her and to the taxpayers who are backing the loan. Her house cost $155,000. Tejada's loan was apparently made on a micro-down payment of just 3.5%, the minimum down payment to qualify for an FHA loan. On top of this, however, she got an additional government backed loan to make improvements. Her total loans amount to $183,0000. In short, she was immediately underwater on her new house.
