<prompt> Human: Apologies for formatting, Im on mobile. We live in British Columbia and approximately 4 years ago, my sister-in-law was denied financing on a new vehicle. She asked my wife if she would co-sign on the loan and she agreed. After a check from the finance office, they got the green light and everything was finished.Now just this week, my wife and I have decided that we want to look into purchasing a new home. My wife calls our mortgage broker to talk about our finances and she was asked about a 40000 loan thats affecting our oweown ratio. My wife told the broker that she was only a co-signer on it and the broker said that it looked like there was more to it. After sister-in-law does some digging, she discovers that the only part of this loan that has to do with her his the payment comes out of her account. My wife is the principal loan holder, there is no co-signer on the loan and all the payments the sister-in-law is making is going towards my wifes credit.On the upside, she hasnt missed a payment yet so my wifes credit is great. Her sister has been paying for her car for 4 years and her credit is still in the tank. Now we cant buy a house at the moment and I dont know if its because the dealership fudged the paperwork to make the sale, A buddy worked for said dealership and told me they were crooked as fuck. Or my wife, her sister and her husband all happened to miss a giant chunk of information while signing papers. I wasnt there when it happened so I cant make any real assumptions.Edit: I was going to let my wife proof read this before I posted it, but she feel asleep before I was finished. Now that she has seen it, she has told me that her sister had a previous loan and a different car that got added to the top of the new load and that is how it became 40000. Very sorry for the confusion this may have caused.Edit 2: For others that have asked, my wife is not on the insurance or registration for the vehicle.  <response>: Yesh, that sounds like a bad situation. Im not sure anything can help. If the SILs credit is still tanked, she wont be able to get a loan to buy the car drom your wife. I think you guys might be stuck until the loan gets small enough. I hope SIL doesnt screw up any payments!
