Cash-Out Refinance vs HELOC: Which Should You Choose?
The core difference in cash-out refinance vs HELOC is what happens to your first mortgage. A cash-out refinance replaces your existing mortgage with a new, larger loan and pays you the difference in cash.
A HELOC leaves your first mortgage untouched and adds a second, revolving line of credit on top. Choose a cash-out refinance when today's rates are near or below your current rate.
Choose a HELOC when your existing rate is low and you want to protect it.
Cash-Out Refinance vs HELOC: Side-by-Side
| Cash-Out Refinance | HELOC | |
|---|---|---|
| Loan structure | New, larger first mortgage that replaces your old one | Second loan that sits behind your first mortgage |
| Rate type | Usually a fixed rate on the whole new balance | Usually a variable rate tied to the prime rate |
| Effect on existing mortgage | Repays and replaces it at today's rate | Leaves it fully intact, rate untouched |
| How you get the money | One lump sum at closing | Revolving credit line you draw as needed |
| Closing costs | About 2% to 5% of the new loan amount | Low or sometimes zero upfront costs |
| Rate behavior | Locked for the life of the new loan | Can rise or fall with the prime rate |
| Best when | Your current rate is high, or you want one fixed payment | Your current rate is low and you want flexible access |
Which should you choose?
Pick a cash-out refinance if your current mortgage rate is at or above today's rates and you want one fixed payment. Pick a HELOC if your existing rate is low, since a refinance would reprice your entire balance at a higher rate.
A homeowner holding a very low mortgage rate almost always keeps it and uses a HELOC for extra cash. Both loans use your home as collateral, so missing payments can lead to foreclosure.
How Each Option Works
A cash-out refinance and a HELOC both turn home equity into cash, but through opposite structures.
A cash-out refinance pays off your current mortgage with a new, bigger loan. You get the difference in cash at closing. You now have one payment at one new rate for the entire balance.
A HELOC is a second loan that leaves your first mortgage alone. It works like a credit card secured by your home. You draw money during a set period and pay interest only on what you use.
Both options usually cap your combined loan-to-value at about 80% to 85%. That limits how much equity you can tap. To see how much you may qualify for, try our mortgage calculator.
The Rate Trap: Why Cash-Out Refinance Can Cost More
The biggest hidden risk in cash-out refinance vs HELOC is repricing your whole loan. A cash-out refinance replaces your entire mortgage at today's rate.
Suppose you owe $250,000 at 3%. You want $50,000 in cash. A cash-out refinance turns your full $300,000 balance into a loan at today's higher rate. You just repriced money you already had cheaply.
A HELOC avoids this. Your $250,000 stays at 3%. Only the new $50,000 carries the higher HELOC rate.
This is the key decision rule. When your current rate is much lower than today's rates, a HELOC almost always wins on total interest. Run both scenarios in our budget planner before you decide.
Costs, Rates, and Payments Compared
Closing costs and rate type separate these two options as much as structure does.
A cash-out refinance carries closing costs of about 2% to 5% of the new loan. On a $300,000 loan, that is $6,000 to $15,000. In return, you usually lock a fixed rate and one predictable payment.
A HELOC often has low or zero upfront costs. But its rate is variable and tied to the prime rate. Your payment can rise if the prime rate climbs, and a HELOC rate is often higher than a first-mortgage rate.
So you trade certainty for flexibility. Weigh both against your long-term plan in our net worth tracker.
Is the Interest Tax Deductible?
Interest on either loan is deductible only if you use the money to improve your home. This rule comes from the Tax Cuts and Jobs Act and IRS Publication 936.
You can deduct the interest if you use the cash to buy, build, or substantially improve the home that secures the loan. A kitchen remodel or an addition can qualify.
You cannot deduct the interest if you use the money to pay off credit cards, buy a car, or cover tuition. The purpose of the funds decides the deduction, not the loan type.
This rule applies equally to a cash-out refinance and a HELOC. Always confirm your situation with a tax professional, since limits and records matter.
Which Should You Choose?
Your existing mortgage rate is the deciding factor in cash-out refinance vs HELOC. It usually matters more than closing costs or convenience.
Choose a cash-out refinance when today's rates are at or below your current rate. You may lower your rate and pull cash in one move. It also suits people who want a single fixed payment.
Choose a HELOC when your current rate is low and you want to protect it. It also fits ongoing needs, like a renovation you fund in stages.
If you are still weighing a refinance itself, compare 15-year vs 30-year mortgage and fixed vs ARM mortgage terms first.
Frequently asked questions
Is a HELOC or cash-out refinance better if I have a low mortgage rate?
A HELOC is almost always better if your mortgage rate is low. A cash-out refinance replaces your entire balance at today's higher rate. A HELOC keeps your low first-mortgage rate and charges the higher rate only on the new money you borrow.
Does a cash-out refinance replace my current mortgage?
Yes. A cash-out refinance pays off your existing mortgage and replaces it with a new, larger loan. You receive the difference in cash at closing and make one payment at the new rate on the full balance.
How much can I borrow with each option?
Both usually cap your combined loan-to-value at about 80% to 85% of your home's value. On a $400,000 home, that leaves roughly $320,000 to $340,000 in total loans, minus what you already owe on your mortgage.
Is the interest on a cash-out refinance or HELOC tax deductible?
The interest is deductible only if you use the money to buy, build, or substantially improve the home that secures the loan, per IRS Publication 936. Using the funds for other purposes, like debt payoff, makes the interest nondeductible.
Which has lower closing costs, a HELOC or a cash-out refinance?
A HELOC usually has lower closing costs, often little to nothing upfront. A cash-out refinance typically costs 2% to 5% of the new loan amount. But a HELOC carries a variable rate that can rise over time.
Can I lose my home with either option?
Yes. Both a cash-out refinance and a HELOC use your home as collateral. If you miss payments, the lender can foreclose. Borrow only what your budget can safely repay, even if rates rise on a HELOC.
