Key takeaways
- A HELOC can work well for planned expenses like renovations. Some HELOCs let you borrow in stages, while others require that you borrow a substantial amount upfront.
- Your home is collateral, and higher rates or the end of the draw period can raise your payments.
- A HELOC lets you keep your existing mortgage rate, unlike a cash-out refinance. Compare both with a home equity loan before deciding.
A HELOC can be a good idea when you’re borrowing for something with lasting value, you can afford the payment after the draw period ends even at a higher rate, and keeping your current mortgage beats refinancing it. If any of those doesn’t hold, a home equity loan, a cash-out refinance, or saving first may serve you better. New to HELOCs? Start with our guide to how a HELOC works.
HELOC pros and cons
| HELOC advantages | HELOC disadvantages |
| Access funds throughout the draw period, subject to your lender’s withdrawal requirements | Your home is at risk if you can’t repay |
| Pay interest only on the amount borrowed | Variable rates can increase your payments |
| Keep your existing mortgage rate | Payments may jump when repayment begins |
| May offer lower rates than credit cards | Your lender can freeze unused credit |
| Interest may be tax-deductible for qualifying home improvements | Fees and closing costs may apply |
5 Questions to Answer Before Getting a HELOC
1. What are you borrowing for?
A HELOC often makes sense for home renovations. Check how much your lender requires you to withdraw at the start, since interest begins on funded money.
Uses that tend to fit
Home improvements are a common fit. Some HELOCs let you draw money as contractors bill you, rather than borrowing everything upfront. Others, including Tomo Mortgage’s, require a substantial initial withdrawal, which can suit a project with a known budget.
The interest may also be tax-deductible. Under IRS rules, the money must be used to buy, build, or substantially improve the home securing the loan, and you must itemize deductions. Other limitations apply, so ask a tax professional.
Other large, one-time expenses can make sense when you have a clear payoff plan.
Uses that need a hard look
Debt consolidation can reduce your interest costs: the Federal Reserve reported an average rate of 22.15% on credit card accounts that incurred interest in the second quarter of 2026. But using a HELOC also turns unsecured debt into debt backed by your home.
The interest generally isn’t tax-deductible when you use the money to pay off credit cards, and any savings can disappear if you start building up credit card balances again.
Uses that carry the most risk
Using a HELOC for groceries, bills, or other everyday expenses can leave you with growing debt and no clear way to pay it off.
And a HELOC isn’t a guaranteed emergency fund. Your lender can freeze the loan, as explained in question 4.
2. Can you afford the payment after the draw period ends?
Budget for the payment after the draw period, because it could be much higher than what you initially pay.
During the draw period, some HELOCs let you pay only interest. Once that period ends, you’ll typically start paying back the principal too, often over 10 to 20 years. Some HELOCs instead require a large balloon payment when the draw period ends. The CFPB explains how these repayment options work.
Here’s how payments on a $50,000 balance could change:
| Payment stage | At 8% interest rate | At 10% interest rate |
| Draw period, interest only | $333/month | $417/month |
| Repaid over 20 years | $418/month | $483/month |
| Repaid over 10 years | $607/month | $661/month |
These hypothetical examples illustrate how payments change based on the interest rate and repayment period. They assume a $50,000 balance, monthly payments, and a fixed interest rate at each stage. Rates shown are not APRs, Tomo Mortgage terms, or an offer of credit. Actual HELOC rates may change, and the payments exclude fees.
If the higher payments would strain your budget, especially during a lower-income year, consider borrowing less, paying down principal early, or choosing a home equity loan with predictable payments.
3. Could you handle a higher rate?
Most HELOC rates are variable, meaning your payment can increase even if you don’t borrow any more money.
Your rate is typically based on an index, often the prime rate, plus an amount set by your lender. Under federal disclosure rules, lenders must also tell you the maximum rate that could apply.
See what your payment would look like if your rate rose by two percentage points. Then check your agreement for that maximum rate, which could be higher still.
Some HELOCs let you convert part of your balance to a fixed rate, making future payments more predictable. Check whether this option is available and what it costs.
4. What happens if your lender freezes the line?
Don’t assume unused HELOC credit will always be available.
Under federal rules, lenders can temporarily freeze new borrowing or reduce your limit in certain situations, including:
- Your home’s value drops significantly, even if you’ve made every payment on time.
- Your financial circumstances change significantly, and the lender reasonably believes you may be unable to meet your payment obligations.
- You default on an important requirement in your agreement.
For freezes or reductions under these provisions, your lender generally must notify you in writing within three business days and explain why. Access must be restored when the condition no longer applies, though you may need to request reinstatement. The lender cannot charge a reinstatement fee, although certain reasonable appraisal or credit-report fees may apply.
That’s why it’s worth keeping a separate emergency fund instead of relying entirely on your HELOC.
5. Is a HELOC better than your other options?
If your existing mortgage has a low interest rate, a HELOC lets you borrow without giving it up.
For context, Freddie Mac reported that the average 30-year fixed mortgage rate was 7.40% on October 15, 2026. A cash-out refinance replaces your entire mortgage at a new rate, while a HELOC charges interest only on what you borrow.
But a HELOC isn’t always the cheapest option. Compare it with:
- Home equity loan: Provides a lump sum, typically at a fixed rate. Better if you know exactly how much you need and prefer predictable payments. Reference our HELOCs vs. home equity loans article for a more detailed comparison.
- Cash-out refinance: Replaces your current mortgage with a larger one. Worth considering if refinancing your existing balance makes financial sense too.
- Personal loan or line of credit: Usually unsecured, so your home isn’t collateral, though rates are typically higher than on borrowing that uses your home as collateral.
- Saving first: Avoids interest charges and putting your home at risk, if the expense can wait.
Compare your total costs, not just rates. As the CFPB notes, HELOC lenders may charge fees, and some plans have minimum borrowing requirements. Fees can include appraisal, application, closing, or annual charges. Selling your home also generally means paying off the HELOC, so upfront costs matter if you might move soon.
Eligibility requirements vary by lender, including how much equity you need and what credit score or income qualifies.

Frequently asked questions
Can I use a HELOC for anything?
HELOCs can generally fund a range of expenses, but you should check your lender’s terms for any restrictions.
What matters most is your ability to repay. Under IRS rules, interest is generally only tax-deductible when you use the money to buy, build, or substantially improve the home securing the line, subject to other requirements.
Can I cancel a HELOC after I sign?
Yes. If your HELOC is secured by your principal home, you generally have until midnight of the third business day after opening the line or receiving the required disclosures and cancellation notice, whichever is later.
You must notify your lender in writing. Under Regulation Z’s cancellation rules, the lender must refund fees paid to open the HELOC, including applicable application and appraisal fees.
