Ok. Here's the deal. My wife's sister is having trouble paying their house payment because they have a ARM loan. I guess they have reached the year limit on the loan and the interest rate shot up a lot on them. they both have bad credit. She's went to banks and mortgage companies and the best rate they can get is like 11%. My sister in-law asked if we could buy their house and rent it to them. We've both got great credit so it shouldn't be a problem getting a loan. The sister in-law owes like $110K on the house. How could this impact my/our credit score? I really don't want to add more debt to my credit report and I'm affraid it will have a negative impact on my score. They want to buy the house back after they improve their credit score. How long could that take? If I sell the house back to them after say 5 years, will I be able to sell it back to them for what they owe? I don't want to get into trouble for selling the house below it's value and that's something to consider. I'm not looking to make money from them, just help them out. I do plan to get into real estate real soon so I'm affraid this will hinder my plans. Any advice would be great. I don't mind helping them out but I don't want it to hurt our credit or future purchases.
