DTI compares your monthly debt payments to your gross monthly income. Lenders use it to determine your ability to manage monthly payments and repay a mortgage.
Front-end DTI (housing ratio) is your housing payment divided by income. Back-end DTI (total ratio) includes all monthly debts plus housing divided by income.
Conventional loans typically require a front-end DTI of 28% or less and a back-end DTI of 36% or less. Some lenders allow up to 45-50% with strong compensating factors.
FHA loans allow a 31% front-end ratio and 43% back-end ratio. With strong credit and reserves, some borrowers can qualify with higher DTIs up to 50%.
USDA loans require 29% front-end and 41% back-end. VA loans have no front-end limit but typically require a 41% back-end ratio, though higher ratios may be allowed.
No, DTI only includes debts that appear on your credit report or are recurring obligations: mortgage, credit cards, car loans, student loans, personal loans, and alimony/child support.
Yes, some loan programs allow higher DTIs with compensating factors like excellent credit (720+), large down payment, substantial reserves, or significant income in certain fields.
Increase income (overtime, side work), pay down credit card balances, pay off car or student loans, avoid new credit before applying, or consider a co-borrower.
