Yes. To add another mortgage, simply add it as a new debt in the "Debts" section. Then priority rank which mortgage (debt) you would like the software to focus on. The primary mortgage is the focus of the software unless a debt is priority ranked higher than that mortgage. If a debt has been ranked higher than the mortgage, the software will counsel your client to pay down any debts first and then it will help them take the necessary actions to pay off the primary mortgage. Make sure to just put the principal and interest portion of the payment in this section. Include the taxes and insurance portion of the payment in the expense section as a monthly expense.
