What is Debt-to-Income Ratio (DTI)?

DTI is a financial metric that helps lenders assess your ability to manage your debt payments relative to your income. It’s expressed as a percentage and represents the portion of your monthly income that goes towards paying your debts. There are two primary components of DTI:

  1. Front-End DTI: This includes your housing-related expenses, such as your monthly mortgage payment, property taxes, homeowners insurance, and any homeowner association fees.

  2. Back-End DTI: This encompasses all your monthly debt obligations, including your mortgage, credit card payments, auto loans, student loans, and other installment loans.

How to Calculate Your DTI

Calculating your DTI is relatively straightforward. You’ll need to divide your total monthly debt payments (front-end and back-end) by your gross monthly income (your income before taxes and deductions). The formula looks like this:

DTI = (Total Monthly Debt Payments / Gross Monthly Income) x 100

For example, if your total monthly debt payments amount to $2,000, and your gross monthly income is $6,000, your DTI would be:

DTI = ($2,000 / $6,000) x 100 = 33.33%

When you qualify for a mortgage loan, your back-end DTI cannot exceed the maximum determined by the loan program you are applying for. Conventional lending will allow up to 50% max DTI and VA and FHA will allow even higher than this in some cases. But, jumbo and portfolio type loans will typically limit you to 43% or 45% DTI.

Excellent! You are in a great position to take on a new home mortgage and likely have a lot of room between what you’re comfortable paying per month for a new housing payment and your maximum payment per month.

While you should pay off your debt as soon as possible, this debt to income ratio should allow you to live the lifestyle you want without major constraints.

Healthy. You should avoid incurring more debts but are still in great shape to qualifying for a new home loan.

You are in a relatively good situation but should consider reducing your debt load so that your new home payment does not limit your ability to save and invest.

Elevated. You should start working on a plan that will help you reduce your debts or increase your qualifying income.  

You can still qualify for a new housing payment above the amount you are currently paying but you are more limited in your ability to go as high as you may need to in order to get the home you desire.

High. Such a debt to income ratio indicates financial strain. You should devote as much money and energy as possible to pay off your loans in preparation for buying a new home.

The maximum debt to income ratio for a new home loan is typically 45-50%.  In this range you are likely to only qualify for a payment the same or slightly higher than your current housing payment.

Dangerous. More than half of your income is used to pay off debts and your current housing payment. If you’re not following a strict payment plan yet, don’t hesitate to consult a financial advisor and get professional help.

In this range it will be extremely difficult to qualify for any new loans to include a new home loan unless the payment is significantly lower than your current housing payment or you drastically reduce debt.

The Impact of DTI on Mortgage Qualification

Now that you understand what DTI is and how to calculate it, let’s delve into why it’s crucial for your mortgage qualification:

  1. Lender’s Risk Assessment: Lenders use your DTI to assess the level of risk associated with lending you money. A higher DTI indicates that a significant portion of your income is already committed to debt payments, which may make it riskier for you to take on additional debt.

  2. Loan Eligibility: Different mortgage programs have varying DTI requirements. Conventional loans typically have stricter DTI limits, while government-backed loans like FHA and VA loans may allow for slightly higher DTIs. Meeting these requirements is essential for mortgage approval.

  3. Monthly Budget: Your DTI also affects your monthly budget. A lower DTI means you have more disposable income each month, making it easier to handle unforeseen expenses or save for the future.

Managing Your DTI for Mortgage Approval

If your DTI is currently on the higher side and you want to improve your chances of mortgage approval, here are some strategies to consider:

  • Pay Down Debt: Reducing your existing debt balances can lower your DTI and make you a more attractive borrower. Pay off debt with higher monthly minimum payments first as this will have the biggest impact on your approval.

  • Increase Income: If possible, look for ways to increase your income, which can improve your DTI ratio. Keep in mind that side hustles and 2nd jobs require a 2 year history of receipt in order to count as qualifying income.

  • Adjust Your Budget: Review your monthly expenses and see if there are areas where you can cut back, allowing you to allocate more funds towards debt payments.

  • Consider Co-Signers or Joint Applications: Including a co-signer or applying for a mortgage with a joint applicant with a strong financial profile can help you qualify for a larger loan amount.

In conclusion, your Debt-to-Income Ratio (DTI) plays a significant role in determining your mortgage eligibility and the terms of your loan. Understanding how DTI is calculated and taking steps to manage it can enhance your chances of securing the mortgage you need to achieve your homeownership goals. Remember that different lenders and loan programs may have varying DTI requirements, so it’s essential to shop around and find the best fit for your financial situation.
