Imagine you're planning a major home renovation, and you need to access a significant amount of money to cover the costs. You’ve built up equity in your home over the years, and now you’re faced with a decision: Should you take out a Home Equity Line of Credit (HELOC) or a second mortgage?

Choosing between a HELOC vs second mortgage can be tricky, especially since both options allow you to leverage your home’s equity. Although they serve similar purposes, each comes with unique features tailored to different financial needs.

What is the difference between a HELOC and a 2nd mortgage?

Is a HELOC a second mortgage? Technically, yes. Both allow homeowners to borrow against their home's equity, and if you draw money from it, it’s essentially a second loan against your home—but they function differently.

“A HELOC provides flexibility as you can draw funds as needed, up to a certain limit, and you only pay interest on the amount you use,” says Peter Lopipero, a former real estate agent and mortgage broker who is now a full-time real estate investor. (It’s sort of like applying for a credit card—even though your credit limit may be $10,000, you don’t have to charge that much.)

In contrast, a second mortgage, also known as a home equity loan, offers a one-time lump sum of money upfront. You repay that loan with fixed monthly payments and (typically) a fixed interest rate for the entire term of the loan.

In this article, we will explore the differences between HELOCs and second mortgages in more detail.

HELOC vs second mortgage: Rates

  • HELOC: “HELOC interest rates generally start lower but are variable, meaning they can increase with market conditions,” says real estate expert Alexis Orivri. The average HELOC rate in 2024 tends to hover around 9% for most borrowers, though this can vary depending on factors such as your credit score and loan-to-value (LTV) ratio.

    Some lenders also offer fixed-rate options or hybrid products that combine fixed and variable rates, allowing you to lock in a rate for part of your loan balance. It’s important to note that while rates can fluctuate, they are influenced by broader market conditions and individual borrower profiles.
  • Second mortgage: These typically come with fixed interest rates, usually around 6%. “Second mortgages offer stability with fixed rates, making payments more predictable,” Lopipero says. These rates are influenced by factors such as the homeowner's credit score, home equity, loan amount, and prevailing economic conditions, making them ideal for those who prefer consistent monthly payments and wish to avoid the rate fluctuations associated with HELOCs.

HELOC vs second mortgage: Repayment

  • HELOC: It offers flexibility during the draw period, typically lasting around 10 years, where you can borrow, repay, and borrow again up to a set limit based on your home equity. You often have the option to make interest-only payments during this time, keeping the principal balance unchanged.

    Once the draw period ends, the repayment phase begins, usually lasting 10 to 20 years. During this time, you'll repay both principal and interest, with monthly payments that are generally fixed. However, since HELOCs usually have variable interest rates, your payments may fluctuate based on market conditions.
  • Second mortgage: It provides a lump sum upfront, with repayment starting immediately through fixed monthly payments that cover both principal and interest. This fixed structure offers predictability, making it easier to manage your budget and long-term financial planning.

HELOC vs second mortgage: Access to funds

  • HELOC: During the draw period, you can borrow, repay, and borrow again as needed, similar to using a credit card. This feature is particularly useful for ongoing projects where the total cost may be uncertain.

    However, once the draw period ends and the repayment period begins, you can no longer withdraw additional funds. At this stage, you’ll start repaying both the principal and interest on the amount you’ve borrowed, with monthly payments that may increase if the interest rate is variable.
  • Second mortgage: On the other hand, second mortgages provide a lump sum upfront with no option to withdraw additional funds later. This structure makes it more suitable for specific, one-time expenses. The repayment terms are fixed, offering consistent monthly payments over the life of the loan, which typically ranges from 10 to 30 years. This can make budgeting easier and reduce financial stress over time.

HELOC vs second mortgage: Pros and cons

Both options offer distinct advantages and risks, and understanding how they align with your financial goals will help you make the best decision for your situation. By weighing these factors carefully, you can ensure your choice meets your financial needs and long-term objectives.

Pros of HELOCs:

  • Flexibility: You can borrow as needed, with access to funds over time for ongoing expenses, like home renovations or education.
  • Interest-only payments (during draw period): Many HELOCs allow you to make interest-only payments during the draw period, making monthly payments more manageable in the short term.
  • Potential tax deductions: If used for home improvements, the interest on a HELOC may be tax-deductible.

Cons of HELOCs:

  • Variable interest rates: Rates can fluctuate, leading to higher monthly payments if rates rise, which may strain your budget.
  • Risk of over-borrowing: The flexibility to borrow as needed can lead to accumulating more debt than initially planned.
  • Foreclosure risk: Since your home is collateral, missing payments could lead to foreclosure.

Pros of second mortgages:

  • Fixed interest rates: A fixed-rate structure offers stability in payments, reducing the risk of fluctuating costs and providing predictability for long-term budgeting.
  • One-time lump sum: Ideal for large, one-time expenses like home renovations, medical bills, or debt consolidation.
  • Potential tax deductions: As with HELOCs, interest may be tax-deductible if the funds are used for home improvements.

Cons of second mortgages:

  • Increased debt load: Taking on a second mortgage increases your overall debt, which can impact your credit score and financial stability.
  • No flexibility: You receive a lump sum upfront with no option for additional borrowing, which may be less ideal for ongoing expenses.
  • Foreclosure risk: Like a HELOC, defaulting on a second mortgage can lead to foreclosure.

HELOC and second mortgage: Impact on credit score

When considering a HELOC or a second mortgage, it's essential to understand the risks and their potential impact on your financial health and credit score.

“Applying for either a HELOC or a second mortgage can temporarily lower your credit score due to the hard inquiry,” Orivri says. “However, both options may improve your credit utilization ratio, potentially boosting your score.”

“High usage or missed payments could harm your credit with either option, but consistent payments can positively influence your credit over time,” she says.

How to choose the right option for you

“A HELOC might be more suitable for those who need ongoing access to funds over time, like for home renovations,” Lopipero says. “A second mortgage could be a better choice for those who need a specific amount for a one-time expense, such as debt consolidation or a large purchase.”

Here’s what to consider when deciding between a HELOC or a second mortgage:

  • Your financial goals: Determine whether you need continuous access to funds (HELOC) or a one-time lump sum for a specific purpose (second mortgage).
  • Interest rate preferences: Decide if you prefer the flexibility of a variable rate (HELOC) or the stability of a fixed rate (second mortgage).
  • Usage of funds: For ongoing expenses, a HELOC offers more flexibility. For a one-time expense, a second mortgage may be more appropriate.
  • Repayment plan: Consider whether you prefer variable payments that fluctuate based on usage (HELOC) or a predictable repayment schedule with fixed monthly payments (second mortgage).
  • Your financial situation: Consider your ability to manage potential rate increases with a HELOC or if fixed payments suit your financial outlook better.

To tailor the choice to your unique situation, consult with a financial advisor or lender who can provide personalized guidance.

FAQs: 2nd mortgage vs HELOC

Is a HELOC considered a second mortgage?

Yes, a HELOC is considered a second mortgage. Both a HELOC and a traditional second mortgage allow you to borrow against the equity in your home, using your property as collateral. The key difference lies in how you access the funds: A HELOC provides a revolving line of credit, while a traditional second mortgage gives you a lump sum upfront with fixed monthly payments.

How can a HELOC be used? And a second mortgage?

A HELOC offers flexibility and can be used for various purposes, including home improvements, debt consolidation, education, or emergencies. However, some lenders may impose limits on borrowing amounts or dictate how the funds can be used.

In contrast, second mortgages are typically suited for larger, one-time expenses such as home renovations, medical bills, or paying off high-interest debt, and generally have fewer restrictions on fund usage.

According to Orivri, “interest on both HELOCs and second mortgages may be tax-deductible if the funds are used for home improvements.” However, if the funds are used for other purposes, such as paying off credit card debt or financing a vacation, the interest will not be tax-deductible.

Can I have multiple second mortgages on my home?

Yes, it is possible to have multiple second mortgages on your home, but it depends on your lender’s approval and your equity in the property. Each additional mortgage increases the risk for lenders, so they will closely evaluate your financial situation, credit score, and the amount of equity you have before approving another second mortgage.

However, it’s important to note that taking out multiple second mortgages can significantly increase your overall debt and monthly payments, which could strain your finances.
