You will need to check with your state's laws regarding how much notice is required.

For mortgage debt, the following additional requirements must be met:the party making the payments is obligated on the mortgage debt,there are no delinquencies in the most recent 12 months, andthe borrower is not using rental income from the applicable property to qualify.
