Fixed-rate HELOCs: Pros and cons

As you pay down your mortgage, you build home equity – the portion of your home you truly own. Homeowners can borrow their equity with a home equity line of credit (HELOC). While most HELOCs have a variable interest rate, it's becoming more common to find lenders offering a fixed-rate option.

Rocket Mortgage doesn't currently offer HELOCs, but homeowners need to learn how fixed-rate HELOCs work and their pros and cons.

What is a fixed-rate home equity line of credit (HELOC)?

A fixed-rate HELOC allows you to avoid the interest rate changes that may increase the amount you owe.

A fixed-rate HELOC lets you convert part or all of your credit line from an adjustable interest rate to a fixed interest rate for a specific time. Your interest rate will revert to a variable rate once the fixed-rate term expires.

A HELOC is a second mortgage that uses your home equity to establish a line of credit you can borrow from as needed. Most HELOCs have adjustable interest rates that fluctuate with broader economic conditions.

HELOCs are commonly used to pay for remodels, home improvements, hospital bills, education expenses, or debt consolidation. Your home serves as collateral on a HELOC, meaning your lender can foreclose on your home if you default on the loan.

How does a fixed-rate HELOC work?

A fixed-rate HELOC works much like an adjustable-rate HELOC, except you can apply a fixed interest rate to some or all of your balance for a specific time.

The fixed-rate period varies, depending on your lender and the terms of your loan, from several years to a full 30-year loan term.

Most HELOCs have a draw period of up to 10 years, during which you can borrow from the line of credit as needed up to your credit limit.

Once the draw period ends, you can no longer withdraw cash and must make payments on the loan until it's repaid with interest.

The repayment period typically lasts longer than the draw period, usually 10 to 20 years.

How are fixed-rate and adjustable-rate HELOCs different?

Until recently, most HELOCs had a variable interest rate. However, lenders offering a fixed interest rate for part of the repayment timeline are becoming more common.

Fixed-rate HELOCs are different from variable-rate HELOC options in a few key ways:

• They have a set interest rate for a set period.
• They might have higher fees than adjustable-rate options.
• When interest rates are rising, a fixed-rate HELOC can help borrowers lock in the current rate before it rises further.

Pros and cons of a fixed-rate HELOC

It's important to weigh the advantages and risks of taking out a HELOC with a fixed interest rate.

Pros

• More predictable payments: Your rate won’t vary, so you’ll know exactly what your monthly payment will be during the fixed-rate period.
• Immunity against inflation: With a HELOC, fixed interest rates protect you from sudden interest spikes. While traditional HELOCs often have lower rates initially, inflation can make them unpredictable.
• Conversion to a variable interest rate: If interest rates drop during the fixed-rate period, some lenders allow borrowers to switch to an adjustable rate. However, there may be additional fees.

Cons

• Limits on the number of fixed-rate balances: Your lender may limit the number of fixed-rate balances you can hold at once.
• Hidden fees: Your lender may incorporate hidden fees with your fixed-rate HELOC. These can include an annual fee, origination fee, fees for every rate lock you choose to initiate, and penalty fees.
• Minimum required borrowing amount: When you borrow from a lender, they usually have a minimum loan amount to qualify you for the fixed-rate option.
• Fewer lenders available: While fixed-rate HELOCs are available, many lenders remain hesitant to offer them.

How to convert a HELOC from a variable to a fixed-rate

Can you switch from a variable to a fixed-rate HELOC? Yes. Here’s how you can go about doing this:

1. Talk with your current lender or shop around. Not all lenders offer a fixed-rate option. Either way, you'll want to explore different possibilities. Requirements, fees, and rates will vary by lender.
2. Apply for your HELOC. Once you find a lender you’re comfortable with, you’ll follow their application process. Be prepared to provide detailed financial information.
3. Close on your loan. Once you’re approved, you’ll be able to close on the loan.

FAQ

Here are some commonly asked questions about fixed-rate HELOCs.

Can I pay off a fixed-rate HELOC early?

It’s always best to check with your lender before assuming anything. In many cases, you can pay off your fixed-rate HELOC early to save money in the long run, but there may be prepayment penalties and fees.

Why aren’t HELOC rates fixed all the time?

Just like with primary mortgages, adjustable-rate options are common. There are benefits and drawbacks to both variable and fixed-rate mortgages, and the same goes for HELOCs. One is not necessarily better than the other, so many lenders offer both.

Is a fixed-rate HELOC high-risk?

All debt carries some risk, but HELOCs involve using your home as collateral. This means it has additional risks, such as foreclosure. A fixed-rate HELOC, however, removes the risk that your rate will increase with the market rate, as with an adjustable-rate HELOC. That said, always carefully consider your finances and explore all options before taking on more debt.

Can I sell my house if I have a fixed-rate HELOC?

Yes, you can sell your house even if you have taken out a fixed-rate HELOC. Be aware that you won’t get any profits from your home sale until you pay off the balance.

The bottom line: When a fixed-rate HELOC may be a good option for you

Fixed-rate HELOCs offer stable payments and are a good option for those who want predictable, unchanging payments. However, interest rates can be unpredictable. If rates drop, you might pay a higher-than-market rate. On the other hand, if rates are on the rise and likely to keep moving in that direction, or you are on a fixed budget, then a fixed-rate HELOC makes a lot of sense.
