Buying your first home is an exciting journey, but it’s also a major financial decision. While you may already be thinking about home inspections, offers, and location, there’s one key aspect of mortgage approval that often gets overlooked until it’s too late: your Debt-to-Income (DTI) ratio. Understanding what this ratio is, how it’s calculated, and how it impacts your mortgage approval is critical to securing the best mortgage rates and setting yourself up for a successful homebuying experience.
In this guide, we’ll dive into the depths of DTI and give you actionable steps to improve your ratio so you can position yourself as an ideal candidate for lenders.
What is Debt-to-Income (DTI) Ratio?
The Debt-to-Income (DTI) ratio is a simple calculation used by lenders to measure how much of your monthly income goes towards paying off debt. In essence, it’s a way for them to gauge your ability to handle new debt—in this case, a mortgage—on top of your existing financial obligations. The lower your DTI, the more confidence lenders will have that you can make your mortgage payments on time.
DTI is expressed as a percentage and is calculated using the following formula:
DTI = (Total Monthly Debt Payments / Gross Monthly Income) × 100
Let’s break it down:
- Total Monthly Debt Payments: This includes payments on things like student loans, auto loans, credit card minimums, and any other debts you’re obligated to pay each month. Lenders will also include your projected monthly mortgage payment in this total.
- Gross Monthly Income: This is your pre-tax income, including wages, salaries, bonuses, and any other income sources such as rental income, side gigs, or investments.
For example, if your total monthly debt payments are $2,000 and your gross monthly income is $6,000, your DTI ratio would be:
(2,000 / 6,000) × 100 = 33.3%
Why Does DTI Ratio Matter?
Lenders use your DTI ratio to assess your financial health and determine whether you can take on the responsibility of a mortgage. Simply put, the lower your DTI ratio, the better your chances of qualifying for a mortgage, and the more favorable your mortgage terms will be. Lenders typically view borrowers with high DTI ratios as risky, as they may already be stretched too thin financially.
Here’s a rough breakdown of what different DTI ranges can mean for your mortgage prospects:
- Under 36%: Generally considered a good DTI ratio. You’re likely to qualify for a mortgage with favorable terms.
- 36% – 43%: This range is often the cutoff for many mortgage programs, including FHA loans. You may still qualify, but your mortgage options could be more limited.
- Over 43%: Lenders see this as risky territory. You may have difficulty getting approved, or you may need to make significant changes to improve your DTI before applying for a mortgage.
Types of DTI Ratios: Front-End vs. Back-End
When it comes to your mortgage, lenders actually look at two different DTI ratios: front-end and back-end.
- Front-End DTI: This ratio only considers your projected housing costs, including your monthly mortgage payment, property taxes, homeowners insurance, and any homeowner’s association (HOA) fees. It’s also known as the “housing ratio.” Lenders prefer a front-end DTI of 28% or less, meaning no more than 28% of your gross monthly income should go towards housing expenses.
- Back-End DTI: This is the more commonly referenced DTI ratio, which includes your total monthly debt payments, including housing and non-housing-related debt (student loans, car loans, credit card payments, etc.). Lenders typically want to see a back-end DTI of 36% or less, although some mortgage programs allow up to 43%.
Both ratios give lenders insight into how well you can manage debt and whether you’ll have enough money left over for living expenses and savings after covering your monthly debts.
How to Calculate Your DTI Ratio
Let’s say you earn $5,500 per month in gross income and have the following monthly debts:
- Student loan: $400
- Car loan: $350
- Credit card minimum: $150
Your total monthly debt is $900. To calculate your back-end DTI, you’d do the following:
($900 ÷ $5,500) × 100 = 16.36%
If you’re looking at homes with an estimated mortgage payment of $1,400, here’s how you’d calculate your new DTI:
($900 + $1,400) ÷ $5,500 × 100 = 41.82%
In this case, your back-end DTI would be just under 42%, which may still qualify you for a mortgage, but with limited options.
How to Improve Your DTI Ratio for Mortgage Approval
If your DTI is on the high side, don’t worry—there are several steps you can take to lower it and increase your chances of getting approved for a mortgage.
1. Pay Down Existing Debts
One of the most effective ways to lower your DTI is to pay off some of your existing debts. Start by tackling high-interest debts like credit card balances or personal loans, which not only lower your DTI but can also improve your credit score. Even making extra payments toward student loans or car loans can help.
2. Increase Your Income
Another way to lower your DTI is to increase your gross income. This could mean asking for a raise at work, taking on a side job, or increasing your business revenue if you’re self-employed. Any boost in income will reduce the impact of your existing debt when calculating your DTI.
3. Avoid Taking on New Debt
Before applying for a mortgage, avoid taking on any new debts. This includes financing big-ticket items like cars, appliances, or furniture. New loans will add to your monthly debt payments and increase your DTI, making it harder to qualify for a mortgage.
4. Refinance or Consolidate Debt
If you have high-interest loans or credit cards, consider refinancing or consolidating your debt to lower your monthly payments. This can reduce your overall debt load and help bring your DTI ratio into a more favorable range.
5. Increase Your Down Payment
The larger your down payment, the smaller your mortgage will be, which means lower monthly payments and a lower DTI ratio. If you have extra savings or access to gift funds from family, consider increasing your down payment to bring your DTI down.
6. Stretch Out Your Mortgage Term
Choosing a longer mortgage term, such as 30 years instead of 15 years, can lower your monthly payment and improve your DTI. While you’ll pay more in interest over the life of the loan, it could help you qualify for a mortgage if your DTI is close to the cutoff point.
How DTI Ratio Affects Your Mortgage Rate
In addition to determining whether you qualify for a mortgage, your DTI ratio can also impact the mortgage interest rate you’re offered. Borrowers with lower DTI ratios are seen as less risky, which means lenders are more likely to offer favorable terms, including lower interest rates. A lower interest rate can save you tens of thousands of dollars over the life of the loan, making your home more affordable in the long run.
Final Thoughts: Planning Ahead for Mortgage Success
Your Debt-to-Income (DTI) ratio plays a pivotal role in your mortgage approval and the terms you’ll be offered. As a first-time homebuyer, understanding and improving your DTI can increase your chances of qualifying for a mortgage with a favorable interest rate.
By paying down existing debt, increasing your income, avoiding new loans, and making smart decisions about your mortgage term and down payment, you can set yourself up for success on your homebuying journey. Take the time to calculate your current DTI, and if necessary, make adjustments well before applying for a mortgage. This proactive approach will give you more control over the process and improve your chances of securing your dream home with confidence.
