ucsf_med have your agent get a preliminary title report to find out all the liens on the home and who is actually on title at the moment. I would not do anything until I found out who is on title and what order the liens are in. If the private lender somehow got title to the home then he is on the hook to pay off the first and second. Chances are that he doesn’t want to go through the hassle of making payments.
I don’t have time to explain right now but there are middlemen operating out there who insert themselves into the foreclosure process to get money out of the deal. I have heard of this but have not run into it yet. You may indeed be running into that right now but I am not sure.
So first and foremost get the pr done. If this person is indeed the new owner then it should be recorded. I wouldn’t do anything until that is completed.
