<prompt> Human: The Details:Im 24, still in college going half-time, never owned a house before, make 33kyr, have a slightly above average credit score. My income vs. expenses are such that I could manage paying the mortgage myself should she not be able to, I have a 4 month emergency stash for special cases. She is about 30, her and her husband make about 60kyr, have 3 kids, a lot of medical bills, and terrible credit. they bought the house for 47k, want to fix it up and sell it for 80-120k, want me to get a 30yr fixed mortgage for 50k, then use some of that to pay off their car, and then rent from me for 2 years while they fix it up to sell. Their mortgage is currently held by her boss who has a 6 interest and the boss wants her to buy it outright or move out within the next 2 months.The PayoffFor using my credit, they will pay me 150 a month on top of the mortgage, insurance, tax. They will pay for: any closing costs, appraisals, repair maintenance. After I will get 25 equity when we sell, or profit if we decide to rent it out when they move out. The Issue:I know mixing family and money should be taboo, but I would hate to see my niece and nephews homeless, and it could potentially be profitable. My question is, from your experiences, will the potential for my credit being ruinedgaining a huge money sink be worth 150-ish a month and 25 equity on the home once we sell?EDIT: I did some more research. I asked other family members who I know she has taken small loan payments from, like using someone elses credit card to buy a household appliance. They miss their payments on that frequently. I called the boss to ask about payment history. DAMN holyf!k shes 34 a year late. She used to rent from her boss at another place and was consistently late on that. That was the last straw. So I told her no, I couldnt buy her mortgage off her so she could just start being late with someone new instead. Annndd then the guilt trip...ooohhh the friggin guilt trip. Its gonna be an awkward Thanksgiving and Christmas.Anyway, thank you all for the advice. Some really solid ideas on what I would have had to do if I did go through with it, and some really good questions were raised that, when answered, helped me to make my decision. Im just going to gift her some money for a down payment on an apartment and help her create a budget this Christmas. Happy holidays!Assistant: So you are going to own the house then? Not quite sure what the proposal is. Of course it is a terrible idea to get financially entangled with someone who has terrible credit but you know that already.Human: Yes, I would own it, put her in a leasing contract so she pays the mortgage plus some extra for me, and we would agree to either sell it or rent it out after she fixes it up. Im just not sure if Im being blind about this because she is my family. The proposal is essentially getting 150 per month and about 15k when we sell the house, for using me to buy the house from them so they dont lose the equity they already put into it. The house is now worth about 67k.  <response>: The deal is also making you an instant landlord with all of the legal responsibilities that entails. Instead of fixing it up, your sister could ruin the house instead and youre left with nothing. She might have the best intentions but good intentions dont make a house flipper successful.
