ORNV3,
I just Googled it and it looks like the 1099 c is cancellation of debt which is covered by the Mortgage Forgiveness Debt Relief Act of 2007. I think this is good news! Here's a link to the info I found on the IRS website:
Home Foreclosure and Debt Cancellation
If I understand it correctly, if they've issued you a 1099 C it looks like you're off the hook for the deficiency (fingers crossed)!!
Let me know what you find out.
