Wow Richard, I can't believe what you are having to deal with. You are making me count my blessings. I only have to deal with a trouble making nutjob sister in law who luckily lives far enough away I don't have to deal with her often.
I hope the renter will stick to her guns and not pay them. A little stomach upset and barfing will do your brother some good, especially if he blows some darling wifey's way.
Hang tough!!
