Keep your low mortgage rate: why a HELOC can beat a cash-out refinance in 2026
The short answer
A cash-out refinance replaces your entire mortgage at today's rate, while a HELOC or home equity loan only charges the new rate on the amount you borrow. If your current rate is well below the roughly 7% market average of September 2026, keeping it and adding a second loan for the cash you need usually costs less in total, even if the second loan's rate is higher.
Side-by-side example
You owe $300,000 at 3.25% and want $60,000 for a renovation.
| Cash-out refinance | Keep first mortgage + home equity loan | |
|---|---|---|
| New borrowing | $360,000 new 30-year loan at 7.0% | Keep $300,000 at 3.25%; add $60,000 at 8.5% over 15 years |
| Approximate monthly principal and interest | About $2,395 | About $1,306 (current loan, if it started as $300,000) + $591 = about $1,897 |
| Upfront costs | Often 2% to 5% of $360,000 | Usually lower, sometimes waived on HELOCs |
Rates are illustrative. Your actual payment on your current loan depends on its original amount and age. The point is that repricing $300,000 from 3.25% to 7% costs far more than paying a higher rate on $60,000.
When a cash-out refinance can still win
- Your current rate is already near or above today's rates.
- You want one loan and one payment and value simplicity.
- You need a large amount relative to your balance, and a second lien would push your combined loan-to-value too high.
HELOC or home equity loan?
A HELOC works well for projects paid in stages and gives flexibility, but its rate is usually variable and rose after the Fed's September 2026 increase. A home equity loan gives a fixed rate and payment for a known amount. Compare them in detail.
Protect yourself
Any loan secured by your home puts the home at risk if you cannot pay. Borrow for purposes that improve your finances or your home, and have a repayment plan.
Common questions
Can I get a HELOC if I have a first mortgage?
Yes. That is the most common setup. The HELOC is a second lien behind your first mortgage.
How much can I borrow with a HELOC?
Most lenders cap total debt on the home at about 80% to 90% of its value. Subtract what you owe on your first mortgage to estimate your maximum line.
