3 Key Things to Know Before Opening a Home Equity Line of Credit

  • Home equity lines of credit, or HELOCs, may be more appealing than a cash-out mortgage refinance or other sources of borrowed money.
  • Last year, HELOC use ticked up as refinancing lost its luster due to quickly rising mortgage rates.
  • However, there are aspects of HELOCs that borrowers should consider before tapping their home equity.

When homeowners look for ways to fund home improvement projects or other expenses, sometimes a home equity line of credit emerges as an option.

HELOCs, as they're called, let you borrow money against a portion of your home's equity — the difference between your mortgage balance and the house's appraised value — up to a certain amount. You can borrow from the HELOC over time as you need the money instead of getting it all at once as you would with a loan. They can also have lower interest rates than some options, and fewer upfront costs.

Yet experts say there are some aspects of HELOCs that you should consider before getting one.

"It's like a credit card against your home's value," said Seth Bellas, a branch manager with Churchill Mortgage.

HELOC use rose as cash-out refis dropped

Last year, as mortgage rates climbed higher, accessing home equity by taking cash against it during refinancing — a so-called cash-out refi — became less appealing.

Rates on mortgages went from close to 3% at the beginning of 2022 to a peak of above 7% in the fall. Right now, the average on a 30-year fixed-rate mortgage is 6.21%, according to Mortgage News Daily.

As cash-out refis fell, HELOC use began to climb. Last year through September, lenders originated HELOCs totaling $214 billion, up from $159.5 billion during the same period in 2021, according to CoreLogic.

"In a low-rate environment, people were looking at cash-out refis," Bellas said. "Now ... a lot of people have a mortgage with a very low rate, so to do a cash-out refi, they'd be paying [a higher rate] on their full mortgage."

"We've had quite a few people over the past 12 months ... elect to go with the HELOC because of that," Bellas said.

How HELOCs compare with other borrowing options

Generally, HELOCs come with low closing costs compared with mortgages or home equity loans, which operate like other fixed-rate loans, with a set length of time to pay back. And if you have good credit, the rate you can get may be lower than what you'd pay for a personal loan or credit card balance.

Right now, rates on HELOCs are 7.75%, according to Bankrate. That compares with personal loan rates of above 10%, for consumers with high credit scores, and about 20% for credit cards, according to

However, like your mortgage, a HELOC is a lien against your house — meaning that if you don't repay as promised, the lender would have the right to foreclose on your house.

"I would not use a HELOC to buy frivolous things or things you can't afford," said certified financial planner David Demming, president of Demming Financial Services in Aurora, Ohio.

"It should be a short-term bill that you're going to pay off within a finite period of time," Demming said.

Here are three key things to consider before signing on the dotted line.

1. Variable interest rates make it tricky to budget

The interest rate on HELOCs is typically variable, meaning it moves up and down based on the so-called prime rate, which banks use as a basis to set rates on a variety of loans. While the Federal Reserve doesn't control the prime rate, the one it does influence — the overnight lending rate among banks — ends up following suit. 

"Because it's variable, it can be tough to budget from month to month," Bellas said.

Right now, the U.S. is in a rising rate environment, although that is expected to shift as time passes. The Fed's rate-setting committee is meeting this week and is expected to raise that overnight lending rate by a quarter percentage point, which means the prime rate will generally tick higher — and so will HELOC rates.

2. It may be difficult to pay off the principal

HELOCs typically only come with monthly interest payments — meaning none of your minimum payment goes toward the principal.

"If you don't have a lot of excess funds and are making interest-only payments, it can be difficult to find the cash and discipline to pay down that balance," Bellas said.

"I've seen people with a $50,000 balance and five years later it's still close to that [amount]," he said.

HELOCs generally have a "draw" period when you can take money out that often lasts 10 years and then a repayment period of, say, 10 or 20 years, when you start paying both interest and principal. And because of that, your payments will jump if you have only been paying interest.

For instance, a $50,000 balance would yield interest-only payments of $312.50 and then jump to $593.51 during a repayment period of 10 years, according to's HELOC calculator.

If your HELOC has a balance when you sell the home, it must be paid off along with the primary mortgage on the house.

3. Beware of transferring debt to a HELOC

Sometimes, homeowners turn to a HELOC to pay off higher-interest debt, such as credit card balances.

On the face of it, shifting high-rate balances to a HELOC could make sense. However, if you don't have a plan to pay off the HELOC, you're just delaying the inevitable, Bellas said.

"The danger is really that you're recategorizing the debt and kicking it down the road," Bellas said. "There's probably a bigger thing that needs to be addressed."
