I will apologize in advance if I missed something from one of your previous posts, but I'm going to ask whether or not you received something in writing from Hanna & Associates. If so, it should list the previous creditor and the current creditor; this should tell you who currently owns the debt. The reason I'm inquiring about this? Fred Hanna's office doesn't usually purchase bad debt - they simply collect it. Now, I could be wrong, as they may have discovered a gold mine in the way of foreclosed 2nd mortgages, but I just haven't seen any of this type of activity involving Hanna's office.
If you are correct, and Hanna did purchase the debt, I'm confident that you can negotiate a settlement, but if I were you I wouldn't do anything until after you have something in writing from Hanna's office, which will help clear up a few of these details for you. And, if settlement is not an option for you, I suggest that you speak with a bankruptcy attorney to determine your qualifications, and whether or not this is a good option for you. I'm betting that it is, as this is a fairly large balance.
Good luck!
