Can you refinance a HELOC? 5 ways to replace, lock or raise your line

8 min read · LenderMatch Learn

Yes, you can refinance a HELOC. You can replace it with a new line from your lender or another one, pay it off with a fixed-rate home equity loan, or roll it into a cash-out refinance of your first mortgage. Some lenders also let you lock part of the balance at a fixed rate or raise your limit. Every option means qualifying again on credit, income and equity.

On an $80,000 balance at 8.50%, those choices range from $533 to $776 a month, and one of them raises the rate on your whole first mortgage. Below: each option, the math side by side, and what it costs to switch. If a new line or loan is the answer, letting several lenders compete shows you the range of offers before you commit to one.

Can you refinance a HELOC? 5 ways to do it

“Refinancing” a HELOC can mean five different things. Here is what each one does:

Refinancing an $80,000 HELOC: a worked example

Say your home is worth $400,000. You owe $210,000 on a 3.25% first mortgage from 2018 ($1,132 a month) and $80,000 on a HELOC at 8.50% (the 7.00% prime rate as of October 20, 2026, plus an assumed 1.50% margin). You pay interest only: $567 a month. Your draw period ends soon.

Principal and interest, calculated by LenderMatch with a standard amortization formula. The 8.00% and 8.25% rates are assumptions for illustration, not quotes. Before closing costs.

The lowest payment is not the cheapest loan. The new interest-only line pays nothing toward the $80,000, so the balance is still there when its own draw period ends. The 15-year fixed loan costs the most each month but is paid off in 15 years, with about $59,700 in total interest at 8.25%.

Your equity sets the ceiling. Together the two loans are $290,000, or 72.5% of the home’s value. A lender that caps all loans on a home at 85% of value would allow $340,000 in total, so a new line could be as large as $130,000. At an 80% cap, it could be $110,000. See how much equity you can borrow for how lenders set that cap.

Can I refinance my HELOC with another bank?

Yes. The CFPB’s HELOC booklet says that if another lender offers you a line of credit, “you may be able to use that to pay off your original line of credit,” and that application and other fees may apply. Typically the new lender pays off the old balance at closing, and the old line is closed so its lien on your home can be released.

Before you apply, compare what the switch costs. The CFPB lists the up-front charges a HELOC can carry: an appraisal fee, an application fee that might not be refunded if you are turned down, and closing costs such as title search and filing fees. Some lenders waive some or all of them. Also check your current agreement for an early termination fee.

One protection applies to every new line on your main home. Under federal law, you can cancel a new HELOC within three business days after it opens, and the lender must return the fees you paid, including application and appraisal fees.

Can you get a HELOC to pay off another HELOC?

Yes. The new line restarts the draw period, so the payment can drop back to interest only.

The trade-off: you are pushing the repayment date out, not paying the balance down. In the example, $80,000 at an interest-only 8.00% costs $6,400 a year in interest and leaves the full $80,000 owed. If your draw period is ending, see HELOC draw period ending for how big the payment jump can be and when a new line makes sense.

Can you refinance a HELOC to a fixed rate?

There are two ways. The first is a fixed-rate lock with your current lender. The CFPB says some HELOCs let you convert some of your balance to a fixed interest rate, which is “typically higher than the variable rate” but gives you a predictable payment. Ask whether a lock has a fee, a minimum amount or a deadline.

The second is a home equity loan, from your lender or a new one, that pays off the line. It turns a moving payment into a fixed one and ends the ability to borrow again. Both choices work best when you no longer need to draw money. See HELOC vs home equity loan for a full comparison.

Can you refinance a HELOC into your mortgage?

Yes, with a cash-out refinance: a new, larger first mortgage pays off both your current mortgage and the HELOC, leaving one payment. Under Fannie Mae’s rules, paying off a HELOC this way counts as a cash-out refinance unless the whole line was used to buy the home. That matters because the new loan then has to meet the cash-out rules, including their limits on how much of your home’s value you can borrow.

It tends to make sense only when your current mortgage rate is close to or above today’s rates. In the example:

Uses the Freddie Mac 30-year fixed average of 7.40% for the week of October 15, 2026. Before closing costs. The cash-out also starts a new 30-year term on the $210,000 you had already paid down for eight years.

Here the cash-out costs $182 more a month, because the rate on the first $210,000 rises from 3.25% to 7.40%. Check your own numbers with the cash-out refinance calculator and our guide to cash-out refinance vs HELOC.

Can you increase your HELOC limit?

Often, yes, but it does not happen on its own when your home value rises. You ask your current lender, and it reviews you again. One consumer lending company’s guide, updated August 12, 2026, says lenders typically look at your equity, credit history and income, may check your home’s current value with an appraisal or an automated valuation, and run a credit check. If approved, you usually keep the same account with a higher limit.

Federal law treats a limit increase on your main home like a new line in one way: you have three business days to cancel the increase. If your lender will not raise the limit, a new, larger line from another lender that pays off the old one does the same job.

What happens to your HELOC when you refinance your first mortgage?

If you refinance only your first mortgage and keep the HELOC open, the HELOC lender usually has to agree to stay in second place behind the new mortgage. Fannie Mae requires any lien that is not paid off to be “clearly subordinate” to the new refinance mortgage. Ask your HELOC lender early how its subordination process works, since the new first mortgage usually cannot close until that step is done.

Is it worth refinancing a HELOC?

It can be when one of these is true:

• Your draw period is ending and the repayment payment does not fit your budget.
• Your rate or margin is high. A new lender may offer a lower margin over the prime rate, especially if your credit has improved since you opened the line.
• You want a payment that cannot change. A fixed-rate lock or home equity loan protects you from rate increases.
• You need more room and your current lender will not raise the limit.

It may not be worth it when the fees eat most of the savings. Divide the total up-front cost by the monthly savings to find how many months it takes to break even, the same math explained in when refinancing makes sense. If you live in Texas, home equity lines follow special state rules; see HELOCs in Texas.

Frequently asked questions

Can you refinance a HELOC during the draw period?

Yes. You can replace or pay off a HELOC at any point, during the draw period or after it ends. Before you do, check your agreement for an early termination fee or prepayment penalty, which the CFPB lists among the HELOC costs to compare.

Can I refinance my HELOC with the same bank?

Often, yes. Your current lender may offer a new line, a renewal, a fixed-rate lock on part of the balance or a higher limit. Expect it to review your credit, income and home value again, the same way a new lender would.

Does refinancing a HELOC hurt your credit?

Applying usually means a hard credit check by the lender you choose, with your permission. Our guide to whether rate shopping hurts your credit explains how inquiries are counted and how long they stay on your report.

Can you refinance a HELOC and get more money?

Yes, if you have the equity. A new line can be larger than the old balance, up to the lender’s combined limit on all loans against the home. In the example in this article, a lender with an 85% combined limit could allow a line of up to $130,000 to replace an $80,000 balance.

Does LenderMatch check my credit?

No. LenderMatch never pulls your credit. A lender you choose may check it, with your permission, when you apply.
