What are the risks of using a HELOC to pay off debt?

Using a HELOC to pay off debt can make financial sense — but it comes with five specific risks that every homeowner should understand before proceeding. The most important: a HELOC converts unsecured debt into debt secured by your home. Credit card default damages your credit score. HELOC default can result in foreclosure.

The other four risks are a variable interest rate that can change over time, the possibility of accumulating new debt after consolidating, a reduced equity cushion if home values fall, and a payment increase when the HELOC's interest-only draw period ends. Understanding each of these fully is what separates a decision that works from one that backfires.

The 5 risks of using a HELOC to pay off debt

Here is a plain-English summary of every risk, in order of severity:

1. Your home becomes collateral. Unsecured debt (credit cards, personal loans) cannot threaten your home. HELOC debt can — non-payment puts your home at risk of foreclosure.
2. Your interest rate can rise. HELOCs carry variable rates. If market rates increase, your monthly payment increases with them, although there are guardrails around this.
3. You may accumulate new debt. Paying off credit cards doesn't prevent you from running them back up. Many borrowers end up with both HELOC debt and new card debt.
4. Your equity cushion shrinks. Drawing down your home's equity leaves less financial buffer if property values fall or you need to sell.
5. Your payment increases sharply when repayment begins. During the draw period, you pay interest only. When repayment begins, you pay principal and interest — often on a larger balance.

Each of these is explained fully below.

Risk 1 — Your home becomes collateral

This is the most important risk to understand, and it's the one most often understated in debt consolidation discussions.

Credit card debt is unsecured. If you miss payments, your credit score suffers and your account may go to collections — but your home is not at risk. A HELOC is a lien against your property. If you cannot make payments, your lender has the legal right to foreclose and sell the home to recover the debt.

In practice, lenders rarely foreclose on a HELOC without first attempting loss mitigation — forbearance, loan modification, and other options are typically available. But the legal risk is real and fundamentally different from anything you face with credit card debt. Before using a HELOC to consolidate, ask yourself honestly: is my income stable enough that I'm confident I can service this debt even in a financial setback? If the answer is uncertain, the risk may not be worth taking.

Risk 2 — Your interest rate can rise

HELOCs carry variable interest rates, typically tied to the prime rate or another market benchmark. When market rates rise, your HELOC rate rises with them, and your monthly payment increases accordingly.

This matters most for borrowers who are consolidating to lower their monthly payment. If rates rise significantly after you open the HELOC, the rate advantage that made consolidation appealing can narrow or disappear. To understand how HELOC rates change over time and what drives movement, that guide covers the mechanics in detail. You can also check current HELOC rates to see where the market stands today before making any decisions.

Risk 3 — You may accumulate new debt

This is the most common reason HELOC debt consolidation fails — and it has nothing to do with the loan structure itself.

When you pay off credit cards with a HELOC, those cards are now at a zero balance. For borrowers without strong spending discipline, that zero balance becomes an invitation. Within months or years, the cards are back at their previous balances — but now you also have the HELOC to repay. You've doubled your debt problem rather than solving it.

Mitigation strategies include closing paid-off accounts, cutting up cards, or reducing credit limits immediately after consolidation. If you've consolidated before and run balances back up, that pattern is important data about whether this approach will work for you. Honest self-assessment here is worth more than any rate calculation.

Risk 4 — Your equity cushion shrinks

When you draw on a HELOC, your combined loan-to-value ratio (CLTV) — the sum of your mortgage plus the HELOC divided by your home's value — rises. The higher your CLTV, the less equity you have as a financial buffer.

If home values decline after you open the HELOC, your equity can erode quickly. At extreme CLTV levels, you could find yourself underwater — owing more than the home is worth — which would prevent you from selling or refinancing without bringing cash to the table. This risk is most acute for borrowers who borrow close to the maximum allowable CLTV and live in markets where values are volatile.

Risk 5 — Your payment increases sharply when repayment begins

HELOCs have two phases: a draw period and a repayment period. Understanding how HELOC payments work across both phases is essential before you consolidate.

During the HELOC draw period — typically 5 or 10 years — you make interest-only payments on the amount you've borrowed. These payments are relatively low. When the draw period ends, the HELOC enters repayment: you pay both principal and interest on the full outstanding balance, amortized over the remaining term, typically 10 to 20 years.

Here's an illustrative example:

Example is for illustrative purposes only. Actual payments will vary based on balance, rate, and repayment term at the time of transition.

This is known as payment shock. Borrowers who consolidate near the end of a draw period — or who don't plan ahead for the repayment phase — are most vulnerable. If your draw period is within a few years of ending, factor the higher repayment payment into your decision now, not later.

When using a HELOC to pay off debt makes sense

Using a HELOC for debt consolidation makes the most financial sense when all of the following conditions are true:

For borrowers who meet all five conditions, the math can work convincingly. Customers who use a Better HELOC or home equity loan to consolidate high-interest debt save an average of $1,279 per month.¹

When it probably doesn't make sense

A HELOC for debt consolidation is worth avoiding when:

Your income is unstable or you're between jobs. The secured nature of a HELOC means missed payments carry consequences that unsecured debt doesn't. If your income is variable or at risk, this is not the right time.

You've run up debt after consolidating before. If you've paid off cards with a loan or HELOC previously and found yourself back in debt within a few years, that pattern is likely to repeat. A balance transfer card with a 0% promotional period and a hard credit limit may be a better fit.

You have thin equity margins. Borrowing close to 90% CLTV leaves very little room for error. A modest home value decline could leave you with no meaningful equity — and if you need to sell in the next few years for any reason, that's a real problem.

You're planning to use it for non-essential or depreciating expenses. Using a HELOC to pay off consumer debt for vacations, electronics, or other discretionary spending is different from paying off medical bills or credit cards accumulated during a one-time hardship. Honesty about how the debt was incurred is part of the risk assessment.

HELOC vs. other debt consolidation options

If you're not sure a HELOC is right, here's how it compares to the main alternatives:

The core tradeoff is straightforward: the HELOC typically offers the lowest rate and the highest borrowing capacity, but it puts your home on the line. Personal loans and balance transfer cards carry no collateral risk but come with higher rates and lower limits. See our full cash-out refinance vs. HELOC comparison if you're weighing those two options specifically.

Also worth noting: HELOC interest is tax-deductible only when the proceeds are used to buy, build, or substantially improve the home that secures the loan. Using a HELOC to pay off credit cards does not qualify for the HELOC tax deduction. This is a common misconception worth clearing up before you factor tax savings into your math.

Frequently asked questions

What are the risks of using a HELOC to pay off debt?

There are five: (1) your home becomes collateral — non-payment can lead to foreclosure; (2) your interest rate is variable and can rise; (3) you may run up new debt on paid-off cards; (4) drawing down equity reduces your buffer against home value declines; and (5) your payment increases significantly when the interest-only draw period ends and full principal-plus-interest repayment begins.

Can I lose my home if I use a HELOC to consolidate debt and miss payments?

Yes. A HELOC is a lien against your home. If you default, your lender has the legal right to foreclose. This is the fundamental difference between HELOC debt and unsecured credit card debt. Credit card default harms your credit. HELOC default can cost you your home. This risk doesn't mean you shouldn't use a HELOC — but it must be understood and accepted before you proceed.

I have $50,000 in credit card debt and enough equity — is it smart to use a HELOC?

It depends on four things: how significant the rate differential is between your cards and the HELOC, how stable your income is, whether you have a track record of not re-accumulating debt, and how much equity you'll have remaining after the draw. If all four check out, a HELOC for $50,000 at a meaningfully lower rate can produce real savings. Use the HELOC calculator to model the monthly payment across both the draw period and repayment period before deciding.

What happens if I use a HELOC to pay off my credit cards and then run them back up?

You now have both the HELOC balance and new credit card debt — a worse position than before you consolidated. This is the most common way HELOC debt consolidation fails. If you have a history of running up balances after paying them off, address the spending behavior first. Closing the paid-off accounts immediately after consolidation is one practical way to reduce the temptation.

Is a HELOC better than a balance transfer card for paying off credit card debt?

It depends on your balance size and timeline. For smaller balances — generally under $15,000–$20,000 — that you can realistically pay off within a 12–18 month promotional window, a 0% balance transfer card may be simpler and carries no collateral risk. For larger balances where a HELOC's lower ongoing rate produces substantial savings and you have stable income and significant equity, the HELOC can be the stronger financial move. The key difference is that a HELOC puts your home at risk; a balance transfer card does not.

What happens to my HELOC payment when the draw period ends?

The payment increases — often significantly. During the draw period, you pay interest only on what you've borrowed. When repayment begins, you pay both principal and interest on the full outstanding balance over the remaining term. On a large balance at a higher rate, this transition can more than double your monthly payment. Plan for the repayment-phase payment before you open the line, not after. The HELOC draw period guide explains the transition in detail.

Is HELOC interest tax-deductible when I use it to pay off debt?

No. HELOC interest is only tax-deductible when the proceeds are used to buy, build, or substantially improve the home that secures the loan. Using a HELOC to pay off credit cards, medical bills, or other consumer debt does not qualify for the mortgage interest deduction. See the HELOC tax deduction guide for the full rules on what qualifies.

I paid off my cards with a HELOC and ran them back up — what should I do now?

Stop using the cards and assess your total debt load. If you have sufficient equity remaining, a debt management plan with a nonprofit credit counselor may be the better path before taking on any more secured debt. If the HELOC rate is still materially lower than your card rates, prioritize paying down the cards to zero first — then close or freeze the cards to prevent further accumulation. Taking out a second HELOC or cash-out refinance to pay off the first is generally a sign that the underlying spending behavior needs to be addressed, not the loan structure.

The bottom line

A HELOC can be a powerful debt consolidation tool — but it works by putting your home on the line in exchange for a lower interest rate. That trade is worth making for the right borrower in the right financial position. It's worth avoiding for borrowers with unstable income, a history of re-accumulating debt, or thin equity margins.

The HELOC pros and cons guide covers the full picture if you want to weigh both sides before deciding. And if you want to see what rate you'd actually qualify for — along with an estimate of your monthly payment in both the draw and repayment phases — it takes about three minutes and won't affect your credit score.

¹ The stated average monthly savings of $1,279 is based on an internal analysis of Better Mortgage customers who funded a HELOC or home equity loan through Better between January 1, 2025 and December 31, 2025 and used the proceeds to consolidate existing high-interest debt. Savings represent the average difference between customers’ prior monthly payments on the consolidated debt and their initial monthly payment on the HELOC or home equity loan at funding. Individual savings will vary based on factors including loan amount, interest rates, credit profile, repayment terms, and the type and amount of debt consolidated. Not all customers will achieve similar savings.
