Investors & landlords

I appreciate the feedback.  My in laws have a mortgage on their house and have also accumulated a lot of other debt ( credit cards, loans, etc).  They can afford the mortgage but not the monthly payments of the other debt.  Their credit score isn’t good and won’t get approved for any loans.   The idea was my wife and I issue a loan to them with deferred interest secured by their house which would get paid back when the house was sold.  Definitely not the most ideal situation but just trying to keep them in their house.
