An Introduction to Debt to Income Ratios

Why Lenders Care About DTI Ratios

No matter how good a person's intents may be, all people eventually run into troubles in life.

People who are nearly maxed out on their monthly living expenses give themselves little room to adjust to sickness in the family, a layoff, an automotive accident, or something else which causes economic hardship.

Lenders typically lend money to people who they believe are likely to pay off their loans in a timely manner. While mortgages are secured by the property they are used to purchase, foreclosing on a home can both be expensive & time consuming.

Lenders like to know that consumers have some economic slack available to help them get through rough patches.

Front End Ratio

The front end ratio can be thought of as what portion of your paycheck goes toward paying for your monthly residential living expenses. It includes the cost of any loan payments along with other required expenses tied to the property including property taxes, homeowners insurance along with any homeowners association dues.

As a general rule of thumb a front end ratio of 28% or below is considered highly desirable, though lenders may allow higher levels for borrowers with strong profiles.

Back End Ratio

The back end ratio can be thought of what portion of your paycheck goes toward paying your monthly residential living expenses AND other debt obligations.

As a general rule of thumb a back end ratio of 36% or below is considered highly desirable, though lenders may allow higher levels for borrowers with strong profiles.

Debt-to-income Mortgage Loan Limits for 2018

Generally speaking, for most borrowers, the back-end ratio is typically more important than the front-end ratio. Here are DTI limits for popular mortgage loans. The soft limits may allow approval using automated underwriting software, whereas the hard limits may require manual approval and other compensating factors like a high credit score or perhaps even a co-signer.
