Who is the student? Are both of your names on those loans? What is the total on the loans? How much equity do you have in the home? Are you in the U.S.? Is he spending responsibly?
Would need a lot of info to give financial advice. I recommend you figure out two budgets - one if he stays in the home, one if he leaves. (Because you have no control over whether he leaves or not). You might also want to consult an attorney just to find out what your financial options are. Do either of you have retirement savings or a pension? Is there a loan on the car that is in your name only but that he drives?
