Families are stressful

We have been dealing with some issues with my mother in law for a few months now, and have been trying to convince her to come and live with us. A few weeks ago we found out that my father in law lost a bunch of important clients (he owns his own company) and that he may not be able to pay his alimony. Mother in law is unemployed now, and owns two house, one that was just rented out and the one she lives in. My husband's brother just called to tell us that she may be losing that house, which was our biggest fear. We had been trying to get her moved out for months so we could go in, pack the house and rent it out, covering most if not all of the mortgage. Now it is a crisis and we need to figure out what to do, because if she keeps sitting there, all of her stuff will be on the curb.
