I have come to the depressing realization that DHs mother will likely be living with us soon. Which isn't all terrible because she will clean the house to a ridiculous degree, BUT she is nuts, she managed to call the police so often at her apartment (on her SO and on my BIL who was living with her) that they are kicking her out, and she smokes like a chimney. Well, her SO is going to jail for the next ten years (probation violation), and BIL has found somewhere else to live. So because she is being kicked out she will likely loose her housing assistance, and currently she is supposed to be staying with her sister but realistically I don't see that working out, two crazies and a bunch more people living together doesn't work out.
Pros: Childcare - I can get a job or go back to school. She loves to Clean.
Cons: She is a nut job.
