Debt to income ratio (DTI) is an important factor to consider when applying for a mortgage. It is calculated by dividing your total monthly debt payments by your gross monthly income. The lower your DTI, the more likely you will be able to get approved for a loan. Lenders prefer a low debt-to-income ratio because it ensures that a borrower can handle their monthly loan payments in addition to their other expenses. Borrowers with a high debt-to-income ratio may be viewed as too risky for a loan and may be turned down. It is important to maintain a healthy DTI to ensure you have a better chance of getting approved for a mortgage.
