Deciding whether or not to pay off your car before applying for a mortgage can significantly impact the terms you get on your loan. As you think through this decision and weigh your options, understanding how mortgages work and how existing debts influence your mortgage application is crucial. This decision involves weighing the benefits of a lower debt-to-income ratio against the potential impact on your ability to save for a down payment or an emergency fund. In this guide, we’ll explore the pros and cons of paying off your car loan before getting a mortgage and how it affects your mortgage application. 

What Is DTI and Why It Matters for Mortgages

Your debt-to-income (DTI) ratio is a simple calculation lenders use to determine how much of your monthly income goes toward paying debts. To find your DTI, add up all your recurring monthly obligations—such as credit cards, student loans, personal loans, and car payments—and divide that number by your gross monthly income.

For example, if you earn $6,000 per month before taxes and spend $2,000 on debt payments, your DTI ratio would be about 33%.

Lenders rely on this figure because it gives them a snapshot of your financial health. A lower DTI ratio suggests you have enough income left over each month to comfortably manage a mortgage, while a higher DTI ratio signals greater financial strain and higher risk for the lender. Most mortgage programs prefer a DTI below 36%–43%, though exact limits vary by loan type.

Understanding your DTI is essential before applying for a mortgage. It not only affects whether you qualify but also impacts your loan terms, interest rates, and the amount you’re approved to borrow.

Understanding the Impact of Car Loans on Mortgage Applications

Your debt-to-income (DTI) ratio is one of the key factors that lenders consider when evaluating how much you qualify to borrow. This ratio measures the percentage of your gross monthly income that goes toward paying your debts, including your car loan. A high DTI ratio can signal financial stress, which lenders view as a higher risk, potentially leading to higher interest rates or even denial of your mortgage application.

Car loans contribute to your DTI ratio, so having an outstanding balance can affect your mortgage application. By paying off your car loan, you lower your overall debt, which can improve your DTI ratio and make you a more attractive applicant for a mortgage that will likely get you better loan terms and lower interest rates.

Pros of Paying Off Your Car Loan Before Applying for a Mortgage

1. Improved Debt-to-Income Ratio for Mortgage Approval

One of the primary benefits of paying off your car loan before buying a home is the improvement in your DTI ratio. With one less debt to account for, your DTI ratio decreases, which can enhance your chances of a favorable mortgage. A lower DTI ratio demonstrates to lenders that you have a manageable level of debt relative to your income, making you a more reliable borrower.

2.  Better Credit Score Before Buying a House

Paying off your car loan can also raise your credit score. A lower credit utilization rate and a history of timely payments will contribute to a higher credit score. Since your credit score plays a crucial role in determining your mortgage eligibility as well as interest rates and terms, improving it can lead to a better mortgage.

3. Greater Mortgage Affordability and Purchasing Power

With a reduced DTI ratio and an improved credit score, you may be able to qualify for a larger mortgage amount. This can increase your purchasing power and allow you to afford a more expensive home or secure a better rate, ultimately saving you money over the life of the loan. Additionally, paying off your car loan early will free up more cash each month. 

Cons of Paying Off Your Car Loan Before Getting a Mortgage

1. Financial Strain from Paying Off a Car Loan Early

One potential downside of paying off your car loan before applying for a mortgage is the financial strain it might impose. Using a significant portion of your savings or diverting funds from other financial goals to pay off the car loan could impact your ability to cover a down payment or manage closing costs associated with the mortgage.

2. Opportunity Cost: Pay Off Car Loan or Invest Elsewhere?

The funds used to pay off your car loan could potentially be invested elsewhere. If the interest rate on your car loan is lower than the potential return on investments or savings, it might make more sense to keep the car loan and invest the funds. Assessing the opportunity cost of paying off the car loan versus investing in other financial opportunities is an important consideration.

3. Losing Liquidity and Emergency Flexibility

Paying off your car loan may leave you with less cash on hand for unexpected expenses. Lenders like to see that you have reserves for emergencies, moving costs, or repairs. If you drain savings to pay off a car, it could signal to underwriters that you’re financially stretched, even with a lower DTI.

FAQs About Car Loans and Home Buying

Does paying off a car loan right before applying for a mortgage raise any red flags?

In some cases, yes. Large lump-sum payments can reduce your liquid savings, which underwriters check to ensure you have enough reserves. If your bank statements show a sudden drop in cash, lenders may question whether you’re financially prepared for ongoing mortgage obligations.

Is it better to make extra payments on a car loan instead of paying it off all at once?

Making extra payments can lower your balance and improve your DTI gradually, while still keeping more cash in your savings account. This strategy may strike a balance between reducing debt and preserving funds for a down payment and closing costs.

Will my mortgage rate automatically improve if I pay off my car loan?

Not necessarily. While eliminating the loan may improve your DTI and credit score, mortgage rates are also influenced by market conditions, your income, down payment amount, and overall credit profile. Paying off the car loan can help, but it doesn’t guarantee a lower rate.

How long after paying off my car loan should I wait before applying for a mortgage?

Your credit report typically updates within 30–60 days after paying off a loan. Waiting at least one full billing cycle ensures lenders see the change in your DTI ratio and credit score before reviewing your application.

Consulting with a Mortgage Lender to Get Feedback

We always recommend that our members consult with a mortgage lender to understand how much they qualify for and what their financial strengths and weaknesses are. Consider asking the following questions to a lender:

  • How will paying off my car loan affect my mortgage application and approval chances?
  • What are the potential financial impacts of using funds to pay off the car loan versus investing them elsewhere?
  • Can you help me evaluate alternative strategies to improve my mortgage application without paying off the car loan?
