Hey NaturalLove
Lenders are always losing documentation and always wanting updates throughout the process, so hang in there and fax it again.
Once you complete the modification you can request they correct their reporting to the agencies, and if you make progress make sure to get it in writing for later years just in case, and it happens, it shows up again.
One concern I had, is that you no longer are living at the property, it could void the agreement cause it is probably a requirement that it remain your primary resident.
Be careful!
