You do need to show some type of small surplus at the end of the month to prove that you can afford to stay in your home.....however, some investors have approved a mod with a deficit, so it depends on the investor.....but in most cases they require a surplus of $100-$250 per month.
Good luck, God bless and please post any other questions you may have.
