Cash-Out Refinance vs. HELOC: Which Fits Your Goals?

When you want to turn home equity into cash, the cash-out refinance vs. HELOC decision is usually the first fork in the road. Both use your house as collateral, and both can provide a large sum at a lower rate than most unsecured debt. But they work in very different ways: one replaces your existing mortgage entirely, while the other sits alongside it as a separate line of credit.

The right choice depends on your current mortgage rate, how much money you need, whether you need it all at once, and how much payment uncertainty you can live with. This guide walks through how each option works, what the main lending rules look like, and a side-by-side example so you can see the trade-offs in numbers.

How a Cash-Out Refinance Works

A cash-out refinance replaces your current first mortgage with a new, larger one. The new loan pays off the old balance, and you receive the difference in cash at closing, minus closing costs. You end up with a single mortgage payment, a new interest rate and a new loan term.

Lenders that sell loans to Fannie Mae and Freddie Mac follow specific rules for these transactions. As of October 2026, their published guidelines include:

Ownership time. Both Fannie Mae and Freddie Mac generally require at least one borrower to have been on the property’s title for at least six months before the new loan, with limited exceptions such as inherited property.
Existing loan age. If the refinance pays off an existing first mortgage, that mortgage generally must be at least 12 months old, measured from note date to note date.
Loan-to-value cap. Fannie Mae’s Eligibility Matrix (dated April 2026) caps a cash-out refinance on a one-unit principal residence with a fixed rate at 80% of the home’s value when underwritten through its Desktop Underwriter system. Other loan types and property types can have different limits.

Individual lenders may add stricter requirements of their own, so treat these as general guideposts, not guarantees.

How a HELOC Works

A home equity line of credit leaves your first mortgage untouched. The CFPB describes it as a line you can draw on repeatedly up to a maximum, with repaid amounts becoming available again, similar to a credit card. If you already have a mortgage, a HELOC is a second mortgage that you pay in addition to your first.

HELOCs have two phases. During the draw period, you can borrow as needed and payments are often low. During the repayment period, borrowing stops and payments often rise sharply. For a deeper look at that shift, see our explainer on the HELOC draw period vs. repayment period.

The CFPB notes most HELOCs have variable rates, so payments can change month to month. Some let you convert part of the balance to a fixed rate, typically at a higher rate in exchange for predictability. Lenders can also reduce or freeze the line if your home’s value drops significantly or your finances change.

Cash-Out Refinance vs. HELOC: Side-by-Side Comparison

Feature	Cash-Out Refinance	HELOC
Effect on first mortgage	Replaces it with a new, larger loan	Leaves it in place; adds a second lien
How you receive money	One lump sum at closing	Draw as needed up to a limit
Interest rate	Fixed or adjustable, depending on the loan	Usually variable
Number of payments	One mortgage payment	Two: first mortgage plus HELOC
Upfront costs	Full mortgage closing costs on the entire new loan	Often lower, but may include appraisal, application and annual fees
Interest charged on	The entire new loan balance	Only the amount you have drawn
Payment predictability	High with a fixed rate	Lower; payments shift with rates and phase changes
Risk of losing access	None once funded	Line can be frozen or reduced

A Hypothetical Comparison in Numbers

The figures below are hypothetical, rounded and simplified. They ignore closing costs, taxes and insurance, and they are not a prediction of rates you would be offered.

Imagine a homeowner whose house is worth $400,000. Five years ago they took out a $250,000, 30-year fixed mortgage at 3.5%. Today they owe about $224,000 and pay roughly $1,123 per month in principal and interest. They need about $45,000 for a project.

Option A: Cash-out refinance. They take a new $270,000, 30-year fixed loan at an assumed 6.5% rate. That pays off the $224,000 balance and frees up around $45,000 before costs. The new principal and interest payment is about $1,707 per month, roughly $584 more than before. Notice that the higher rate now applies to the entire $270,000, not just the new $45,000, and the 30-year clock restarts.

Option B: HELOC. They keep the 3.5% first mortgage and open a HELOC, drawing $45,000 at an assumed 8.5% variable rate. An interest-only draw-period payment would be about $319 per month. If the balance were later repaid over 20 years at the same rate, the HELOC payment would be about $391. Combined with the first mortgage, total monthly principal and interest would run about $1,442 to $1,514, assuming the HELOC rate holds steady.

In this scenario, keeping a low first-mortgage rate makes the HELOC cheaper month to month, even at a higher rate on the borrowed portion. The picture could flip if the existing mortgage rate were higher than today’s refinance rates, or if HELOC rates rose substantially.

When a Cash-Out Refinance May Make More Sense

Current rates are at or below your existing rate. If refinancing would not raise the rate on your main balance, the biggest drawback largely disappears.
You want one predictable payment. A fixed-rate refinance locks in a single payment for principal and interest.
You need a large, known amount right away. A lump sum suits one-time costs with a clear price tag.
You also want to change your loan term or type. For example, moving from an adjustable-rate loan to a fixed-rate loan. Our guide on what to know before refinancing your mortgage covers the broader decision.

When a HELOC May Make More Sense

Your current mortgage rate is low. A HELOC lets you keep it untouched.
Your costs will arrive over time. Ongoing projects or uncertain expenses fit a line you draw only when needed, paying interest only on what you use.
You want lower upfront costs. HELOC setup costs are often smaller than refinancing an entire mortgage, though the Federal Reserve’s consumer guide notes fees can still run into the hundreds of dollars.
You can handle variable payments. You should be comfortable with a payment that can rise when rates go up and when the repayment period begins.

Costs, Risks and Tax Points to Weigh

Closing costs. A cash-out refinance carries closing costs on the whole new loan, which can include origination charges, an appraisal and title fees. Always compare your Loan Estimates. A HELOC may involve appraisal fees, application fees, annual fees and per-draw transaction fees.

Foreclosure risk. Both options put your home on the line. The CFPB cautions that falling behind on a HELOC could cost you your home, and the same is true of any mortgage.

Equity drain. Pulling cash out lowers your equity, which can leave less cushion if home prices fall. Our article on whether you lose home equity when you refinance explains how that works.

Taxes. According to IRS Publication 936 (for 2025 returns), interest on home equity loans and lines of credit is deductible only if the money is used to buy, build or substantially improve the home securing the loan, and overall mortgage debt limits apply ($750,000, or $375,000 if married filing separately, for debt taken out after December 15, 2017). Tax rules can change, so confirm current rules with the IRS or a tax professional.

Frequently Asked Questions

Can I get a cash-out refinance soon after buying my home?

Generally not right away. Fannie Mae and Freddie Mac guidelines usually require at least six months on title, and an existing first mortgage being paid off generally must be at least 12 months old, with some exceptions.

How much equity can I take out?

It depends on the lender and loan program. For a conventional cash-out refinance on a one-unit primary home, Fannie Mae’s April 2026 Eligibility Matrix caps the loan at 80% of the home’s value for fixed-rate loans underwritten through Desktop Underwriter. HELOC limits are set by each lender.

Is a HELOC rate always higher than a mortgage rate?

Not always, but HELOCs are second liens and usually carry variable rates, so they often price differently from first mortgages. Compare actual offers rather than assuming.

Can I refinance later if I choose a HELOC now?

Usually, yes, but the HELOC lender may need to agree to remain in second position, or the HELOC may need to be paid off as part of the refinance.

Bottom Line

A cash-out refinance trades your existing mortgage for a new, larger one with a single payment and a lump sum of cash. A HELOC keeps your first mortgage intact and gives flexible access to funds at a usually variable rate. If your current rate is low and your needs are spread out over time, a HELOC often costs less each month. If you want predictability, need one large sum, and today’s rates are close to or below your existing rate, a cash-out refinance may be the cleaner choice. Compare official Loan Estimates and total costs before deciding.
