How Debt-to-Income Ratios Affect Mortgage Approval
Debt-to-income ratios is one of the biggest hurdles in getting approved for a mortgage loan. Not all income counts when it comes to mortgage qualification. Verified and qualified income is the only income that can be used for debt-to-income ratio qualificatin. The debt-to-income ratio (DTI) is a key financial metric used by lenders to assess a borrower’s ability to manage monthly payments and repay debts. It is particularly important in the context of mortgage loans. The debt-to-income ratio is calculated by dividing the borrower’s total monthly debt payments by their gross monthly income and expressing the result as a percentage.
The formula for calculating the debt-to-income ratio is as follows:

The total monthly debt payments typically include housing-related expenses (such as mortgage payments, property taxes, and homeowners insurance) as well as other debts like car loans, student loans, and credit card payments.
For mortgage loans, lenders often look at two types of debt-to-income ratios:
<strong style=”background-color: transparent; font-family: inherit; font-size: inherit; color: var(–bb-body-text-color);”>Front-end ratio (or housing ratio): This ratio includes only housing-related expenses (mortgage, property taxes, homeowners insurance, and sometimes homeowners association fees). Lenders usually prefer this ratio to be below a certain threshold, often around 28% to 31%.
<strong style=”background-color: transparent; font-family: inherit; font-size: inherit; color: var(–bb-body-text-color);”>Back-end ratio (or total debt ratio): This ratio includes all monthly debt obligations, not just housing-related expenses. This includes housing expenses along with other debts. Lenders typically have a maximum allowable back-end ratio, often around 36% to 43%, although this can vary.
Different lenders may have slightly different criteria for acceptable debt-to-income ratios, and these ratios can also depend on the type of mortgage and the borrower’s overall financial profile. It’s essential for borrowers to be aware of their debt-to-income ratio and work to keep it within the acceptable range to improve their chances of qualifying for a mortgage loan at favorable terms.
