A home equity line of credit looks simple on a lender’s homepage: a rate, a credit limit, and an apply button. The contract behind it is not. Draw periods, rate margins, minimum draws, and early-closure fees decide what a HELOC actually costs, and most first-time borrowers never ask about half of them.
That fine print matters more this fall. The Federal Reserve raised its benchmark rate by a quarter point on September 16, 2026, which moved the prime rate from 6.75% to 7.00% and nudged up the cost of nearly every variable-rate HELOC in the country. Americans are still borrowing anyway: HELOC balances rose $13 billion to $459 billion in the second quarter, the 17th consecutive quarterly increase according to the New York Fed.
Before you sign anything, here are the seven things every first-time HELOC borrower should confirm in 2026.

1. The Draw Period Ends, and Your Payment Jumps
Every HELOC has two phases. The Consumer Financial Protection Bureau explains that you borrow during a draw period, often around ten years, and then move into a repayment period where you pay principal and interest. Depending on your agreement, you may even owe the full balance at once when the draw period closes.
Draw periods are not uniform. NerdWallet notes that the typical HELOC offers a 10-year draw and up to 20 years of repayment, yet online lenders such as Figure and Achieve limit borrowing to five years.
The bigger surprise is the payment jump. Take a $50,000 balance at 7.50%. Interest-only payments during the draw period come to about $312.50 a month. Once repayment starts, the same balance amortized over 20 years costs about $402.80 a month, a 29% increase. Over a 15-year repayment term, it climbs to roughly $463.51, nearly 48% more.
Confirm before signing: the exact draw length, the repayment length, whether the minimum payment is interest-only, and whether any balloon payment applies.

2. Your Rate Is Variable, and It Just Went Up
Most HELOC rates are built from an index plus a margin. The index is usually the prime rate published in The Wall Street Journal, and lenders add a fixed margin on top, as shown in Avidia Bank’s July 2026 HELOC disclosure. Prime generally sits three points above the federal funds rate, so when the Fed moves, your HELOC rate follows, often at the next billing cycle.
The math is easy to run. On a $50,000 balance, every quarter-point increase adds about $10.42 a month in interest. A full percentage point adds about $41.67. September’s hike is small, but it is a reminder that variable rates move in both directions. You can review the full rate picture in our guide to HELOC interest rates in 2026.
| Expert InsightJesse Haddad, a loan officer at Next Door Lending, told NerdWallet that borrowers often fear the variable rate without realizing it tracks prime: “The prime rate is pretty predictable as far as how the market goes.” |
Ask your lender for: the margin (not just today’s rate), the lifetime rate cap, what any introductory rate resets to, and whether you can convert part of your balance to a fixed rate. A fixed-rate option is worth weighing if you would otherwise choose a lump-sum home equity loan, which averaged 8.15% in mid-September.
3. Your Credit Limit Is Set by a CLTV Cap
Lenders do not let you borrow all of your equity. They use a combined loan-to-value (CLTV) limit, which counts your first mortgage and the new line together. NerdWallet reports that most lenders allow up to 85% of your home’s value minus what you owe, though some go further. The Mortgage Reports lists Navy Federal at up to 95%, and NerdWallet shows Farmers Bank of Kansas City offering HELOCs up to 100%.
Here is how it works on a $400,000 home with a $220,000 mortgage balance:
- At an 85% CLTV cap: $400,000 x 0.85 = $340,000, minus $220,000 = a $120,000 maximum line.
- At an 80% CLTV cap: $320,000 minus $220,000 = a $100,000 maximum line.
Your appraisal sets the home value, so a low valuation shrinks the line. Borrowing well under the cap also tends to earn better pricing.
4. Some Lenders Make You Draw the Whole Line on Day One
The flexibility of a HELOC is that you borrow only what you need. Not every product works that way. NerdWallet’s lender reviews flag that both Figure and Achieve require you to withdraw the full loan amount at closing. By contrast, many bank and credit union HELOCs set no minimum advance at all, as Avidia Bank’s disclosure states.
The difference is real money. On a $100,000 line at 7.50%, a mandatory full draw means about $625 a month in interest from the first statement. If your project only needs $30,000 right now, drawing as you go keeps that cost near $187.50.
If you plan to keep the line open as a backup fund, also ask about inactivity fees, which Bankrate puts at $5 to $50 on lines that go unused.
5. The Rate Is Not the Whole Cost
HELOC closing costs run 2% to 5% of the line, or $2,000 to $5,000 on a $100,000 line. On top of that, Bankrate lists annual fees of $5 to $250, transaction fees, and rate-lock fees of around $50.
“No closing cost” offers usually carry a catch. The Mortgage Reports found that Bank of America charges $450 plus reimbursement of covered costs if you close the line within 36 months, and U.S. Bank charges 1% if you close within 30 months. As Alliant Credit Union explains, these early-closure fees let lenders recover setup costs they waived, which matters if you might sell or refinance soon.

| Bank of America | About 85% | Not disclosed | None | $450 plus covered costs if closed within 36 months |
| U.S. Bank | 80% | 660 | $75 (waivable) | 1% fee if closed within 30 months |
| Navy Federal CU | Up to 95% | About 620 | None | No early-closure fee found; membership required |
| Figure | 85% | 600 | None | Full draw at closing; 5-year draw period |
| FourLeaf FCU | 85% | 670 | None | Repay closing costs if closed within 3 years; 12-month intro rate |

6. Approval Hinges on Credit, DTI, and Equity
Minimum credit scores vary by lender. In NerdWallet’s September 2026 lender table, Figure and Achieve start at 600, Farmers Bank of Kansas City at 660, and FourLeaf at 670. The best pricing typically goes to borrowers with scores above 740, a debt-to-income ratio of 36% or lower, and at least 15% to 20% equity left in the home.
Expect a hard credit check and paperwork similar to your original mortgage: proof of income, your Social Security number, and a home valuation. If you are close to a threshold, see how to qualify for a HELOC in 2026 for steps to strengthen your file first, then compare written offers side by side using our HELOC lender comparison framework.
7. The Fine Print: Freezes, Foreclosure Risk, and Taxes
A HELOC is secured by your house. The CFPB notes that if you already have a mortgage, a HELOC counts as a second mortgage you pay on top of the first. Miss enough payments and foreclosure becomes possible.
Most HELOC agreements also let the lender freeze or reduce your available credit if your home’s value drops significantly or your finances change materially, even with a spotless payment record. Treat the unused portion as useful, not guaranteed.
Finally, set tax expectations. Interest is deductible only when the money is used to buy, build, or substantially improve the home securing the loan, and the combined mortgage debt cap is $750,000. The One Big Beautiful Bill Act made those limits permanent instead of letting them expire after 2025. Our HELOC tax deduction rules guide covers the details.

The Bottom Line
A HELOC is still one of the cheaper ways to borrow in 2026, and its average rate sits below both home equity loans and most unsecured credit. But the headline rate tells you the least. The margin you negotiate, the fees you avoid, and the draw rules you accept decide the real cost, especially now that prime is rising again.
Get every one of these seven answers in writing, compare at least three offers, and borrow only what you could still repay if rates climb another point. If you are still weighing products, our HELOC vs. home equity loan comparison can help you decide which structure fits your plans.
Frequently Asked Questions
What are the most important things to know before opening a HELOC in 2026?
Confirm the draw and repayment periods, the margin over prime, the CLTV cap, any minimum draw, the full fee schedule, the approval tiers, and when the lender can freeze your line. With prime at 7.00% after the September 2026 Fed hike, the margin and fees matter more than the advertised rate.
What credit score do I need for a HELOC?
Many lenders accept scores in the 600 to 670 range, based on NerdWallet’s September 2026 lender data. Scores above 740 usually unlock the lowest margins.
How much can I borrow with a HELOC?
Multiply your home value by the lender’s CLTV cap, often 85%, then subtract your mortgage balance. A $400,000 home with a $220,000 mortgage supports a line of up to about $120,000 at 85%.
Will my HELOC rate rise after the Fed’s September 2026 hike?
If your line is variable and tied to prime, yes. Prime rose to 7.00%, and many HELOCs adjust at the start of the next monthly billing cycle. The Fed’s next meeting is October 27 to 28, 2026.
Can I open a HELOC and not use it?
Yes, as long as the lender has no minimum draw requirement. Check for annual or inactivity fees, which can make an unused line cost money.
What happens when my HELOC draw period ends?
You can no longer borrow, and payments switch to principal plus interest. On a $50,000 balance at 7.50%, that can raise a $312.50 interest-only payment to about $402.80 over a 20-year term.
Can I lock a fixed rate on a HELOC?
Many lenders let you convert part or all of your balance to a fixed rate. Bankrate notes rate-lock fees of around $50, so ask how many conversions are allowed.
Is HELOC interest tax-deductible in 2026?
Only if the funds buy, build, or substantially improve the home that secures the line, and only within the $750,000 combined mortgage debt limit. You also need to itemize deductions.
Does closing a HELOC early cost money?
It can. Lenders such as Bank of America and U.S. Bank charge fees or recapture waived closing costs if you close within roughly 30 to 36 months.
