The Hidden Trap in Today's HELOC Rates Nobody Mentions

Homeowners are sitting on a record $35 trillion in home equity, and lenders are practically drooling. HELOC ads are everywhere right now, promising flexible cash at rates that sound almost reasonable. But dig past the headline numbers, and the story gets a lot less friendly. Here's the pitch: a home equity line of credit lets you borrow against the chunk of your house you actually own. Unlike a fixed-rate home equity loan, a HELOC is a revolving credit line with a variable rate—meaning it moves up and down, mostly up, tied to the prime rate, which follows the Federal Reserve. And that's the first thing the ads gloss over. The average HELOC rate currently hovers around 8% to 9%, depending on the lender and your credit. That's not a typo. Compare that to a 30-year fixed mortgage, which has been flirting with the mid-6% range. You'd be borrowing at a *higher* rate than a first mortgage, on money secured by your home. Why? Because HELOCs are second liens. If you default, the primary mortgage gets paid first. Lenders price in that risk—and then some. The "convenience" premium you're paying is real. There's a second trap: most HELOCs come with an introductory teaser rate. Maybe it's prime minus a bit, or a promotional 5.99% for six months. Then it resets. And unlike a fixed mortgage, you can't refinance your way out easily if rates spike, because you're already at the mercy of the index. Then there are the fees. Annual maintenance fees. Early closure fees if you pay off the line and close it within two or three years. Application fees. Some lenders even charge a fee just to keep the line open, whether you use it or not. None of this shows up in the big bold rate on the website. So who benefits from the HELOC boom? The banks, obviously. They're collecting higher interest on a loan that's secured by an asset they know you don't want to lose. They also get to keep you as a customer, cross-sell you other products, and lock you into a relationship. The Federal Reserve's rate hikes made existing home equity lines more expensive for millions of borrowers, but lenders didn't exactly rush to pass along savings when rates paused. Consumers who tap equity to consolidate credit card debt or fund a renovation might come out ahead—if they actually pay down the principal and don't treat the line like a checking account. But the data suggests many don't. A 2024 study found that a significant share of HELOC borrowers make interest-only payments, stretching the debt for years. Here's the uncomfortable truth: a HELOC isn't free money. It's a second mortgage with a moving target for a rate. If you're considering one, ask three questions the ads won't answer. What's the maximum rate I could pay? What are all the fees, including the ones buried in the fine print? And what happens if my home value drops and the lender freezes or reduces my line? That last one happened to thousands of borrowers in 2008, and it can happen again. The equity in your home is real. The rate on a HELOC is not as stable as it looks. Treat it like the adjustable-rate debt it is, not a convenient piggy bank. **Closing opinion:** HELOCs can be a useful tool for disciplined borrowers, but the marketing around them is designed to make a variable, second-lien loan feel like a safe bet. The banks profit either way—you only win if you read the fine print and plan for the worst-case rate.
