When I got my mortgage 16 years ago I had a friend co-sign, he was the primary borrower, I had no credit history at the time. I have made all payments, he is in& out of jail, I don't know where he is. I did get a quit claim in 2001 from him, he is still on the mortgage. I am going to pay off loan soon, do I need to find this person to do that? What if I can't find him? Thanks.
