You probably thought that taking out a second mortgage was the right thing to do at the time. It could have been a home equity loan to pay off high-interest debt or a home equity line of credit (HELOC) to help pay for school. But now that interest rates are going up and your financial goals are changing, you might be wondering if you can refinance a second mortgage. Yes, if you meet the lender's requirements, the short answer is yes. Refinancing a second mortgage may give you the flexibility you need if you want to get a better rate or lower your monthly payments.

Key Takeaways

You can refinance a second mortgage, whether it’s a home equity loan or HELOC.
Common reasons for refinancing a second mortgage include lowering your interest rate, reducing monthly payments, switching to a fixed rate, or consolidating multiple loans.
The refinancing process is like that of a primary mortgage, starting with shopping around for the best lender, rate, and terms.
Before refinancing, consider both the benefits and the potential drawbacks, which may include closing costs, strict qualification requirements, and the potential for extending your loan term.

But now, with changing interest rates and shifting financial goals, you may be wondering: can you refinance a second mortgage? The short answer is yes, if you meet lender requirements.

If you’re interested in securing a better rate or lowering your monthly payments, refinancing a second mortgage may offer the flexibility you need.

Can you refinance a second mortgage?

While it is possible to refinance a second mortgage, it’s important to understand the full picture before moving forward.

A second mortgage is secured by your home and taken out in addition to your primary home loan. And just like with your original mortgage, refinancing a second mortgage can help you secure better terms, such as a lower interest rate or a more manageable payment schedule.

To qualify, lenders review multiple factors like your credit score, income, debt, and your home’s current value. Common requirements include:

A credit score of at least 620 (700-plus for more competitive rates)
A debt-to-income (DTI) ratio of 43% or lower (total debt payments divided by gross monthly income)
At least 15% to 20% equity in your home
Documentation such as pay stubs, tax returns, and mortgage statements

Why would you refinance a second mortgage?

There are several reasons why you may decide to refinance a second mortgage:

Savings: If you qualify for a lower rate, refinancing could help lower your monthly payments.
Convenience: If your second mortgage is a variable-rate loan, you may want to refinance to a fixed-rate. It’s also possible to consolidate both mortgages into a single loan for easier management.
Equity: If you have enough equity, consolidating both mortgages into a cash-out refinance could provide funds for big expenses like home improvements or high-interest debt repayments.

Whatever your reasons for pursuing a refinance, be sure to consider the pros and cons before you make your decision. Let’s explore some of the top advantages and potential drawbacks.

Advantages

Refinancing a second mortgage can offer potential benefits, including:

Lower interest rates that reduce overall borrowing costs
The ability to switch from a variable to a fixed interest rate, providing more predictable payments
Reduced monthly payments for better cash flow
The option to consolidate your first and second mortgages into a single loan
Access to your home’s equity via a cash-out refinance

Drawbacks

While refinancing can be helpful, it’s important to weigh the potential downsides:

Expect to pay closing costs and fees amounting to 3% to 6% of your loan principal
Stricter qualification requirements based on credit, income, and equity if you are consolidating both mortgages
Extending your loan term can result in paying more interest over time
Potential loss of favorable terms from your original second mortgage

How to refinance your second mortgage

Once you’ve weighed the pros and cons of refinancing your second mortgage and you’ve decided to move forward, what’s next?

Fortunately, the process is relatively simple, and it’s like refinancing a primary mortgage. Here’s what you can expect:

Review your current loan. Start by looking over the terms of your current second mortgage, taking note of its interest rate, payment structure, and prepayment penalties. Knowing this information at the start will help you evaluate refinance offers.
Check your credit and financial health. As with any home loan, lenders will assess your credit score, income, home value and equity, and debt-to-income ratio (a measure of your ability to take on debt). The better your financial health, the more likely you are to qualify with the best possible rate and terms.
Compare refinance options. It pays to shop around for lenders. Compare rates, fees, and loan terms, and consider if you want to keep your second mortgage separate or roll it into a refinance of your first mortgage.
Gather the documentation. You’ll likely need to provide lenders with income statements, tax returns, home valuations, and details about your current mortgages.
Apply and close. Choose a lender and complete the application process. If approved, you’ll move forward toward closing, which includes final paperwork and fees.

Understanding how to refinance a second mortgage can help you enter the process with your eyes wide open, prepared to make informed decisions that support your financial goals — whether this includes saving money or simplifying your financial situation.

Is refinancing right for you?

Before you decide if refinancing your second mortgage is the right strategy for you, ask yourself the following two questions:

Do I meet the necessary criteria to refinance?
Would refinancing help me reach short-term or long-term financial goals?

Consider, for example, your current interest rate. If today’s rates are lower than that of your current second mortgage and your goal is to pay less, refinancing could save you money over time.

You’ll also want to look at how much equity you’ve built in your home, as well as your credit score. Both will impact your ability to refinance with improved terms. More equity typically means lower risk for lenders, which can help you secure a lower rate. Likewise, a higher credit score can improve your chances of approval and open the door to better loan options.

If you feel that overall, your financial situation has improved since you took out the loan, it might be a good time to refinance your second mortgage. But, if you’re planning to move soon or your credit has taken a hit since your last loan, you may be better holding off until conditions are more favorable.
