When applying for a mortgage, lenders look at more than just income. They also consider how much of that income goes toward monthly debt payments.
This is called your debt-to-income ratio, or DTI.
DTI compares your monthly debt payments to your gross monthly income, which is your income before taxes and other deductions.
Lenders use this number to help understand how a new mortgage payment may fit into your budget. Different loan programs have different DTI guidelines, so there isn't one number that works for every borrower.
Understanding your DTI before buying a home can help you get a clearer picture of your financing options.
