There are two calculations. The first or Front Ratio is your housing expense-to-income ratio. This is to say your proposed mortgage payment (principal, interest, taxes and insurance) divided by your gross monthly income. The second or Back Ratio is your total monthly obligations-to-income ratio. This is your gross monthly payment including Mortgage PITI divided by your gross monthly income.
Lenders will review all consumer debt. The total amount of debt will be factored against a consumer’s income to calculate a debt-to-income ratio. If your debt exceeds 45% your monthly gross income, your chances for a loan approval will decrease.
An applicant’s liabilities are reviewed for cash flow. Lenders need to make sure there is enough income for the proposed mortgage payment, after other revolving and installment debts are paid.
Include principal, interest, taxes, hazard insurance, mortgage insurance & hoa fees.
Do not count installment loans that have less than 10 months remaining. Lease payment must be included in the DTI regardless of the remaining number of payments.
