All monthly expenses are considered as a debt in calculating your debt to income ratio. Any fixed payments that your are obligated to pay need to be notated. The credit report will list most of these items with your payment history. We do not count utilities, most insurance, groceries or other discretionary expenses.
What will need additional document is based on your situation...
obligations such as child support, alimony or IRS debts. You can provide documentation such as a court order or divorce decree along with payment history.
If you have an IRS obligation, three monthly payments must have been made to be eligible for a mortgage loan. Otherwise proof of total payment is required. So for any tax returns presented, we must show that the check for payment has cleared your asset statement.
