Frequently Asked Questions
A DTI below 36% is generally considered excellent. If your DTI goes above 43%, most traditional lenders will not approve you for a mortgage.
DTI calculations strictly use your Gross Income (your income before taxes and deductions are taken out). This is why you must budget carefully, as your actual take-home pay is much lower.
