You went through chapter 7 2 years ago and found your 2nd mortgate listed on your credit report as discharges and included in bankruptcy 0 balance what does this mean?

It may mean the credit report is in error. It may mean there was no equity supporting the second mortgage and your lawyer filed a motion to "strip" it down (especially if it was before the 2007 changes took effect). It may mean you do not owe the second mortgage any more.

It is unclear if the credit report is a new one, and you don't say if you've been paying the second mortgage since then.
