My neighbor went through this when he rented out his house to somebody who turned out to be a serial rent dodger. The guy knew every legal trick in the book, and got to live rent-free for 6 months. In the mean time, my neighbor almost lost the house because he had depended on part of the rent money to pay for his mortgage.
