Front-end and back-end debt-to-income ratios
Many mortgage lenders consider two different debt-to-income ratios when they're deciding whether to give you a mortgage loan and how much to lend. The two ratios include:
- The front-end ratio: The front-end ratio is the amount of your monthly income that will go to housing costs after you've purchased your home. It takes into account your property taxes; your insurance; your mortgage payment of principal and interest on your mortgage loan; and any homeowner's association fees. You'll divide the total value of housing costs by your income to get the front-end debt-to-income ratio for mortgage approval.
- The back-end ratio: The back-end ratio considers your housing costs along with all of your other debt obligations. To calculate this, add up all of your financial obligations, including your housing costs, loan payments, car payments, credit card debts, and other outstanding loans.
Lenders generally consider both types of debt-to-income ratios; however, the back-end ratio is typically more important because it gives lenders a big-picture view of your finances.
If your housing costs will be a little bit high relative to your income but you have no other debt payment obligations at all, a lender may be more willing to lend to you. This is because your total financial obligations will still be manageable even with that bigger mortgage loan.
What debt-to-income ratio do lenders want to see?
Typically, lenders want to see a front-end debt-to-income ratio of 28% and a back-end ratio of 36%. However, some conventional lenders will allow a back-end ratio of up to 43%. If you're able to obtain a loan through a program with government backing, such as an FHA loan, your back-end debt-to-income ratio could go as high as 50%.
The lower your debt-to-income ratio, the more likely you'll be to qualify for a loan at a favorable mortgage interest rate. This is especially if you have other positive factors, such as a good credit score.
How to improve your debt-to-income ratio for mortgage borrowing
Unfortunately, many people have too much debt relative to their income to qualify for a mortgage loan. High monthly loan payments can result in a debt-to-income ratio that's too high to obtain a home loan.
To improve your debt-to-income ratio for mortgage approval, you could try to earn more so you have a higher income relative to your debt. You can and should also try to pay down debt aggressively so you have less debt that counts toward your monthly financial obligations.
Buying a lower cost home could also help, as this could reduce your mortgage loan costs as well as costs for property taxes and insurance.
A good debt-to-income ratio is key to qualifying for a home mortgage
It's a good idea to know what your debt-to-income ratio is before you apply for a mortgage so you can make certain you're able to afford to borrow as much as you need.
If you don't make enough to qualify, you'll need to scale down your expectations for the amount you can borrow. Alternatively, you could pay off your other debts before applying for a home loan. Calculating your debt-to-income ratio for mortgage loans is easy: Just add up what you owe and compare it to your income and you'll figure out this important number.
