Will I lose my home if I file bankruptcy?

Not if it has less than $250,000 in equity, and if you can afford to make the regular payments.  If you are current on your home mortgage payments and if you can still afford the regular payments under your current mortgage contract, bankruptcy will not affect your home.  This is a factually specific question and you should consult an attorney.  This answer assumes that you qualify for the Arizona homestead exemption.
