Loan Modification before or after a 13?

[Ann]

Well, I need yet more advice here.. Before I decided to file for bk I was in the process of asking for a loan modification on my mortgage and my second mortgage. Now I have since learned about lien stripping. I have not paid my 2nd mortgage for 2 months now. I'm waiting to see what will be offered from them. Should I not do a loan mod now on both before I file or what? I think my second mortgage is really an unsecured debt at this point. I don't want to have to do a quick file (in case they try to foreclose) because I want to "plan" my bankruptcy as recommended here. Also, can the second mortgage foreclose on my home if I'm only 1 payment behind on my first or even if I'm current on my first? Thanks. Learning more and more here everyday!
