HELOC vs. Cash-Out Refinance: Which One Should You Use?

You’ve got equity in your house and something you need to pay for. Two products can get you there, and they work almost nothing alike.

HELOC vs. cash-out refinance usually comes down to one question most people never ask: what happens to the mortgage you already have? One product replaces it. The other leaves it alone. That single difference decides the answer more often than anything else.

HELOC vs. cash-out refinance: what’s the real difference?

A cash-out refinance replaces your existing mortgage with a new, larger one. A HELOC sits behind it and leaves your first mortgage untouched.

Take the cash-out first. You pay off the loan you have, take out a bigger loan, and receive the difference. When it’s done you have one mortgage — a brand new one, at today’s rate, on today’s terms.

A HELOC is different in kind, not just in size. HELOC stands for home equity line of credit. It’s revolving credit secured by your house, more like a credit card than a mortgage in how you use it. You get a credit limit. Draw what you need, when you need it. Interest accrues only on what you’ve actually drawn, not on the full line.

Here’s the part that matters. Your original mortgage keeps running exactly as it was. The HELOC takes a second position behind it.

Which one fits if your current rate is low?

The HELOC, usually. And this is the whole ballgame for a lot of homeowners right now.

Think about what a cash-out refinance actually does to a mortgage you like. It pays that loan off. Every dollar of the new balance — including the part you already owed — comes at the new rate. If you locked in something attractive a few years ago, a cash-out hands it back.

A HELOC doesn’t touch it. You keep the first mortgage on its original terms and borrow separately against the equity above it.

Now flip it. If your existing rate is higher than what’s available today, the calculus reverses, and consolidating everything into one new first mortgage can make real sense. Our cash-out refinance page covers how that path works.

So before you compare anything else, look up the rate on the loan you already have. That number does most of the deciding.

What does a cash-out refinance require?

Seasoning, and two separate clocks have to finish.

Fannie Mae’s rules, updated effective December 10, 2025, set the standard. At least one borrower has to have been on title for six months before the new loan disburses, with limited exceptions for property you inherited or received through a legal award. And the first mortgage you’re paying off generally has to be at least twelve months old, measured note date to note date.

One useful exception: subordinate liens of any age can be paid off through a cash-out refinance. The twelve-month rule applies to the first mortgage.

What this means for you is simple. If you bought recently, a cash-out may not be available yet regardless of how much your equity has grown. A HELOC may still be, since it doesn’t refinance the first mortgage at all.

How does the repayment actually work on a HELOC?

In two stages, and the second one surprises people.

A HELOC has a draw period followed by a repayment period. During the draw period you can borrow, repay, and borrow again against the line. When the draw period ends, the line closes to new borrowing and you repay what’s outstanding.

Most HELOCs carry a variable rate, which means the rate moves with an index over time. A first mortgage at a fixed rate does not. That difference is the main risk in the trade, and you should size your borrowing with it in mind rather than assuming today’s payment is the permanent one.

Ask any lender two questions before you sign: how long is each stage, and what happens to the payment when the draw period ends. You can read through the structure on our HELOC page, but the answers should come in writing for your specific line.

What is the three-day right of rescission?

It’s a federal cooling-off period that lets you cancel, and whether you get it depends on the property.

Under 12 CFR 1026.23, when you take a loan secured by a lien on your principal dwelling, you have three business days after closing to rescind — to unwind the transaction entirely. The clock starts at the latest of three events: when the loan is consummated, when you receive the rescission notice, or when you receive all material disclosures. Nobody disburses money during those three days.

Two limits are worth knowing.

First, purchase and construction financing on your home is excluded. Buying a house doesn’t come with a rescission right. Refinancing one, or putting a HELOC on it, generally does.

Second — and this one lands hard on the Grand Strand — the protection applies to your principal dwelling. A loan against a beach condo you don’t live in, or against a rental in Surfside, doesn’t carry it. Plenty of homeowners here assume the three days are automatic on any loan. They aren’t.

Can you get either one on a second home or a rental?

Sometimes, and the menu narrows considerably.

Cash-out refinancing on a second home or an investment property is a standard product with its own pricing and reserve expectations. HELOC availability on non-primary property is much more limited, because lenders treat a second-lien line on a property the borrower doesn’t live in as a different level of risk.

On a condo, there’s a further layer. A first-lien refinance runs through project review, so the building’s finances, insurance, and owner-occupancy mix all get examined alongside your file. That review can matter more than your own qualifications.

Bring me the address before you plan around either product. Availability on a specific building isn’t something worth guessing at.

When is borrowing against your house a bad idea?

When you’re converting a debt that can’t take your house into one that can.

Consolidating credit cards into home equity is the classic example. The math often looks great. What the math doesn’t show is that you’ve moved unsecured balances onto a lien against the roof over your head, and cards that get paid off have a way of filling back up.

Consolidation works when something structural changed — the spending that created the balances has stopped, or a real income shift makes the new plan sustainable. It doesn’t work as a reset button. I’d rather say that plainly than write you a loan that makes next year worse.

One more thing worth checking with someone who isn’t me. Whether the interest you pay is deductible depends on how you use the money, and that’s a tax question. Ask your CPA before you assume anything about it.

What’s the one thing to do?

Write down the rate on your current mortgage, then decide whether you’re willing to lose it.

That’s the fork. Willing to lose it, and a cash-out refinance is on the table with everything it simplifies. Not willing, and you’re looking at a HELOC, which means you’re comparing a variable rate against keeping a fixed one.

Everything else — how much equity you have, what you need the money for, how fast you want it — matters after that question, not before it.

Frequently asked questions

What’s the difference between a HELOC and a cash-out refinance?

A cash-out refinance replaces your existing mortgage with a new, larger loan and pays you the difference, so your original loan and its rate go away. A HELOC is a revolving line of credit secured by your home that sits in second position behind your existing mortgage, leaving that first loan and its terms in place.

How long do I have to own my home before a cash-out refinance?

Under Fannie Mae’s requirements updated effective December 10, 2025, at least one borrower must have been on title for six months before the new loan disburses, with limited exceptions for inherited property or property received through a legal award. The first mortgage being paid off generally must be at least twelve months old, measured note date to note date.

Do I get three days to cancel a HELOC or a refinance?

Under 12 CFR 1026.23, a loan secured by a lien on your principal dwelling generally carries a three-business-day right of rescission, starting at the latest of consummation, delivery of the rescission notice, or delivery of all material disclosures. Purchase and construction financing is excluded, and the right does not apply to a property that isn’t your principal dwelling.

Should I use a HELOC or a cash-out refinance if my mortgage rate is low?

A HELOC usually fits better, because a cash-out refinance pays off your existing mortgage and reprices the entire balance at current terms. A HELOC leaves your first mortgage untouched. The tradeoff is that most HELOCs carry a variable rate that can move over time.

Can I get a HELOC on a rental property or second home?

Sometimes, though availability is much narrower than on a primary residence, since lenders view a second-lien line on non-owner-occupied property as higher risk. Cash-out refinancing on a second home or investment property is more widely available, with its own pricing and reserve requirements. On a condo, project review applies to a first-lien refinance.
