How Each Works and When to Use Them

Home equity lines of credit (HELOC) and mortgages are both borrowing methods that utilize a homeowner's property, each serving specific needs. Mortgages provide a lump sum amount for purchasing a home or refinancing an existing loan, which is repaid through fixed payments over time. In contrast, HELOCs allow homeowners to borrow against their accumulated equity, offering flexible borrowing options as needed while some HELOCs require the full loan amount to be withdrawn at the time of origination (with additional draws during the draw period as the balance is paid down).

Here, we'll examine thedifferences between HELOCs and mortgages, such as interest rates, repayment structures, eligibility criteria, and when each option is most useful.

HELOC vs. Mortgage: At a Glance

When comparing HELOCs and mortgages, the key differences come down to how funds are accessed, repaid, and used.

What Is a HELOC?

A home equity line of credit (HELOC) is a type of loan that allows homeowners to borrow funds against the equity they've built in their home, which functions similarly to a credit card. HELOCs generally function as revolving lines of credit that use your home as collateral. Borrowers can withdraw money as needed during a draw period , or specific lump sums, depending on the lender requirements, often using it to pay for home renovations or debt consolidation. Similar to a credit card, HELOCs allow homeowners to borrow up to a maximum credit limit and only repay the amount borrowed with interest.

HELOCs are also examples of second mortgages because they're secured by the home in addition to an existing primary mortgage, meaning the lender has a secondary claim to the property if the borrower fails to repay. These loans often have variable interest rates, which can cause monthly payments to change over time.

What Is a Mortgage?

A mortgage is a loan used to buy real estate, secured in an agreement between a lender and borrower. The lender provides a lump sum of money upfront, and the borrower repays it over the loan term. The home acts as collateral, meaning the lender reserves the right to take the property if the loan isn't repaid. Most mortgages are paid in monthly installments that include both principal and interest over terms of 15 to 30 years.

While a HELOC is considered a secondary mortgage, financial decisions like a cash-out refinance are considered primary mortgages. These replace an existing home loan. In a cash-out refinance, you take out a new, larger mortgage, pay off your original loan, and receive the difference in cash, all under a single updated loan agreement.

Key Differences Between HELOCs and Mortgage Loans

While HELOCs and mortgages seem similar, they differ in a number of ways.

How They're Used

Mortgages are used to purchase a home or refinance an existing mortgage.Products like cash-out refinances are often used to access home equity, but they do so by replacing an existing mortgage loan with a larger one. Refinances will also be fixed with a clear repayment plan determined by the loan terms.

HELOCs are only used once homeowners have built up sufficient equity in their home and want to access this equity without refinancing their whole mortgage. Depending on the type of HELOC offered by your lender, you may receive the full loan amount at the beginning with subsequent draw features (such as Freedom Mortgage's HELOC) or be able to draw funds from your equity during a set period. You and your lender can go over what's most convenient for your goals, whether it's ongoing or unpredictable expenses, home renovations, emergency expenses, or even college tuition.

HELOC Rates vs. Mortgage Rates

HELOCs typically use a variable interest rate, which is a fluctuating interest rate that changes based on market conditions. This rate flexibility may cause monthly HELOC payments to change, with 2026 average interest rates currently sitting around 8%–8.5%, according to the Wall Street Journal. HELOC rates are generally a bit higher than mortgage rates because of the increased risk for lenders.

In most cases, mortgages are fixed-rate loans, which keep monthly principal and interest payments the same for the life of the loan. Despite some mortgage products offering variable rate options, like adjustable-rate mortgages (ARMs), mortgage rates still tend to be more stable options with lower interest rates than HELOCs.

Benefits and Risks

Both mortgages and HELOCs have their own unique benefits and downsides. Here are a few to consider:

HELOCs

Pros

• Flexible access to funds
• Only pay interest on the amount borrowed
• Typically lower upfront costs
• Can be used to pay for ongoing or unexpected expenses

Cons

• Usually have variable interest rates
• Higher interest rates than most mortgage products
• Uses your home as collateral

Mortgages

Pros

• Lower interest rates than HELOCs
• Fixed monthly payments over the life of a loan
• Clearly defined repayment schedules

Cons

• Higher upfront costs
• Can't access home equity without refinancing
• Interest is paid on the entire loan immediately
• Also uses your home as collateral; risk of foreclosure if the mortgage goes unpaid

Repayment

Unlike mortgages, HELOCs have what's called a "draw period," which is a predetermined window of usually up to 10 years in which homeowners can borrow money from their home equity as needed. During this time, they might pay interest, but they won't pay on the principal until they enter the repayment period, when they can no longer withdraw funds. Instead, homeowners begin repaying the principal with interest.Repayment periods can last anywhere from 10 to 20 years, depending on loan terms.

The repayment process for mortgages is a bit more straightforward. Once a prospective owner's mortgage application is approved, the lender will provide the funds needed to purchase the home, and the borrower will be expected to repay the loan with interest through fixed, monthly payments over a predetermined loan term.

Tax Considerations

Mortgage interest is usually tax-deductible if the loan is secured by a home and used to purchase, build, and or improve a primary or secondary residence. Homeowners may also deduct property taxes, though these deductions do have their limits, or "caps."

In contrast, HELOC interest is tax-deductible only if the funds are used for substantial improvements on the property that secures the loan. Using withdrawn money for other purposes, like debt consolidation or everyday expenses, will generally exempt these funds from deduction eligibility.

Home Equity Line of Credit vs. Mortgage Requirements

When comparing mortgages and HELOCs, lenders review several key factors to determine eligibility. While both require borrowers to meet certain thresholds, the specific criteria can vary depending on the type of loan, especially HELOC requirements.

• Credit: Most mortgages require homebuyers to have a credit score of 620 or higher, while FHA loans accept applicants with scores as low as 500-580. For HELOCs, lenders often have credit requirements of 660 or higher, with stronger scores allowing for better rate options.
• Debt-to-income ratio (DTI): HELOC lenders traditionally require a DTI of 43%-50%. Most lenders for conventional mortgages will only accept borrowers with DTI below 36%, although some accept maximum DTIs of up to 50% if borrowers have a high credit score or make a large down payment.
• Down payment: HELOCs themselves don't require down payments; instead, they can be used to fund down payments on primary mortgages. Most mortgages, however, usually require down payments ranging from 3.5% to 20% of the loan value.
• Closing Costs: For mortgages, closing costs range from 2% to 6% of the purchase price, while HELOC closing costs can be anywhere from 0 to 5% of the mortgage value. These fees can cover much of the same expenses associated with a mortgage, often with fewer third-party fees and lower initial costs.
• Home equity: HELOCs typically require homeowners to have at least 15%–20% equity in their home to qualify, since you're borrowing against what you already own. Primary mortgages used to buy a home don't require existing equity, but refinance options like cash out refinances typically require you to leave about 20% equity in the home after refinancing.

Is a HELOC or Mortgage Right for You?

HELOCs are great options if you already own a home and need flexible access to the equity. Since it functions as a revolving line of credit, it's particularly beneficial for ongoing expenses like home renovations or tuition,. However, borrowers should beware of HELOC's fluctuating payments due to its variable interest rates, and their home will serve as collateral.

Mortgages, on the other hand, are often better suited for larger, one-time expenses, such as home purchases or refinancing existing loans. A mortgage is also a stronger choice for borrowers looking for housing options with lower interest rates and more predictable repayment plans, especially in fixed-rate loans.

HELOC vs. Mortgage FAQs

Here are some commonly asked questions about HELOCs and mortgages.

Is a Home Equity Line Of Credit Considered a Mortgage?

Technically, HELOCs are regarded as revolving lines of credit, but they are also considered secondary mortgages–not primary mortgages like conventional loans or VA loans.

Which Is Better for Refinancing, HELOCs or Mortgages?

It depends on your goal. A mortgage refinance, like a cash out refi, is better suited for homeowners looking to replace their existing loan, get a lower interest rate, or change the terms of their loan, while HELOCs are a more flexible option for those seeking ongoing access to credit for expenses like debt consolidation without refinancing their entire mortgage.

Is a HELOC or Mortgage Better for Home Renovations?

Given that HELOCs allow homeowners to borrow funds as needed, these would be better suited for long-term renovations where costs are spread out over time. Mortgage products like cash-out refinances are likely better options for renovations that warrant fixed, one-time payments upfront.

Final Thoughts: Understanding HELOCs vs. Mortgages

HELOCs and mortgages each offer distinct advantages. HELOCs offer unique flexibility and allow borrowers to draw funds over time, but they typically come with a variable interest rate and function as a second loan on top of your existing mortgage. A mortgage, by contrast, provides stability through structured monthly payments and often fixed rates, and is commonly used as a primary or replacement loan when purchasing or refinancing a home.

If you're ready to take the next step and explore your options, applying for a HELOC can help you determine how much equity you can access and what terms you may qualify for.
