Hello Ethan, Debt to income ratio, or DTI, compares how much you owe each month to how much you earn. Lenders add up all your monthly debt payments, credit cards, car loans, student loans, plus your new mortgage payment, then divide that by your gross monthly income. Most lenders want to see that number under 43%, though some loan programs allow a bit higher depending on other factors like credit score or down payment size. It's basically their way of gauging whether you can comfortably handle a new mortgage payment on top of everything else you already owe. Lower DTI usually means better loan terms and more buying power, so paying down existing debt before applying can genuinely help.
