<prompt> Human: Hello everyone, Im not quite sure if this is the right subreddit for this post but i am kinda desperate for advice as i need it by sometime tomorrow. Let me start off by saying that i inherited a house when i was 8 years old from my grandfather and i split ownership with my father, to the best of my knowledge everyone was allowed to come through and get any personal property, mementos, keepsakes, etc from the property and that turned a few members of the family into vultures. My stepsister has always been more of a childthats the best, most polite way i can put it starting arguments, guilt tripping for money, a substance abuser at certain points and there have been some allegations of much more serious problems and events that i have heard from other family members. My dad had always given in to her demands and pleas at nearly every request, I informed my mom that when he passed i wouldnt baby her like he had. Well my father passed away a year ago this month, he left her a cabinet, table, his truck, and he asked mom to give her a certain writing desk, all of which i am fine with. The house is a bit run down but we just had someone come in and explain that it wont be a terrible amount of work to make it livable, we are planning an auction of nearly all the items on the property, and offered to sell the house to my stepsister for only 10,000, she can only do contract for deed and we talked and agreed at 400mo for rent and 2,000 out of the auction for the roof to be given to her IF the auction makes a substantial amount. some tools to fix the roof and a couple of other small items. Today she asked that rent be set to a happy medium, some money from my car that i am selling, extra items, the welder, air compressor, grinder, more items in the house, and the agreed terms from yesterday including the 2,000 from the auction and said well talk about the other stuff Monday. At this point we just want the house off our hands and the money from the car and auction, and would have no problem just auctioning off the lota home and two garages with a fairly sizable yard. So i guess my question is, What should i do about my stepsister and would it be wrong to call off this shady agreement and just auction off the house if she continues with how shes acting? Any and all advice would be highly appreciated.I may sound bitter about my father but Im not i love and miss him, I spent most of my life taking care of him, as ive always lived with him and my mom, especially in his last few years, i stayed home and did my best to help himEdit 1: Shes also said that everything not sold at auction will stay in the garage and that If you need anything you can come get the key from meEdit 2: Shes my half sister, not step sister, sorry. Tl;dr: My problematic half sister who has been known to be greedy, use family, and con people is starting to act shady about a house Im selling her and auction of the contents, what do you think i should do about her and would it be wrong to just auction off the property itself?  <response>: Dont sign anything. Not a thing.You need to stop giving stuff to your sister. Have an estate sale or auction and sell all of the belongings. Dont tell your sister that youll give her anything. If the sale makes a profit, then you could decide to give her cash from it.If your sister wants the house, she needs to get a mortgage for it. If she cant get a mortgage, you need to just sell the house on the open market auction, regular sale.... Dont let your sister move into the house unless she buys it or you could end up spending to get her out when she becomes a squatter.Dont give your sister anything to which she isnt entitled.
