Fraud on a loan application
under Federal Law can be $10,000+ and imprisonment.
BK will not protect you since the lender can file a request for relief of automatic stay and file a motion to quash the BK due to a fraudulent loan application.
It appears that you applied for a no-doc stated loan.
AT the time of loan application, you needed to state your true income and not fabricate your income to make the ratios work to qualify for the loan. That is why you could not make your mortgage payments since your actual income was less then that which was stated on your loan app.
