回複：What makes you so sure the situation would change..

A lot of times, if the house is foreclosed or in the process of being foreclosed on, the tenants take advantage not to pay the rent. The bank has a lot of other important things to worry about, they are not as dilligent in collecting the rent either. By the time the buyer takes over the house, he/she will find that the tenants have stopped paying the rent for a couple of years. When those tenants are used to not paying the rent, it is very hard to make them pay again. That's why you need to get rid of those tenants first.
