I have a sister who lived in dad's rental unit free at first...then dirt cheap $350 a month.(he even paid for her utilities!) Dad felt sorry for her after she ran off with a guy from the internet....leaving her kids behind. She moved into dad's rental after she moved back to hometown ( after internet guy got some other woman pregnant and help her blow her divorce settlement from her husband) and had no place to stay. fast forward. 5 years. She found a new guy....moved in with him. Left her now grown son in dad's rental to pay the 350 a month. Every time she has a fight she threatens her new guy with moving back to dad's rental with her son. (which son doesn't want to happen) Anyway...we now need to sell the rental because mom has Alz. and dad has glaucoma, can't drive, hard of hearing...poor judgement. Failed the cognitive assessment test at Doctors. They now need the income they can get from selling this rental. He can't take care of it anymore.....( I have hired people to care for them.....) and dad does not want to move. Doctor suggested nursing home for both parents. The problem...my sister keeps sending me text messages causing problems, and threatening me in voice mails because my uncle and I have co _poa and she thinks we need to discuss everything with her. We have told them we will have to sell the rental...and she threatens that we will never see her and her children again, that when my parents do pass away...she will not help with anything, That I will be alone, my husband will divorce me, my children will hate me, and that even my older sister can't stand me. I pretty much ignore her ranting because she sounds crazy. We did get her son a lease(dad never made them sign one) to cover him for the next year and hopefully when it gets sold, the new owners will honor the lease and maybe let him to sign a new one. Even knowing he has a lease...she is ranting that I am "kicking my godchild out on his A--. . A couple years ago she made the comment that she" doesn't understand why dad just doesn't GIVE her the rental!" It's like she feels entitled to it or something. Dad never thought ahead...never planed for an event like Alz. He needs all his income...it is too late for planning because of the 5 years look back period. My sister doesn't hear anything I tell her.Any suggestions on how to handle her? Dad always made the mistake of handing things to her...getting her out of jams...and it seems she expects me to do the same with her threats. I have been caring for my parents for 4 years now...am over there once a week somtimes more. It is a 50 mile round trip for me. My sister hasn't been there for 6 months at a time. When she does visit it is like a BIG deal for her. What can I do? She is wearing me out with her nonsense.Any suggestions?
