If you need to pull money out of your house, you have two mainstream options and they suit opposite situations. Choosing wrongly is expensive in a way that is not obvious for several years.
#What each one actually is
A cash-out refinance replaces your existing mortgage with a larger one and hands you the difference. You end up with a single loan, a single payment and a new rate applied to the entire balance.
A HELOC leaves your existing mortgage untouched and adds a second, revolving credit line secured against your equity. You draw what you need, when you need it, and pay interest only on the drawn balance.
That structural difference drives everything else.
#The decisive question: what is your current rate?
If your existing mortgage is at 3.2% and current rates are 6.4%, a cash-out refinance is usually a serious mistake. To borrow $60,000 you would reprice your entire $310,000 balance from 3.2% to 6.4%, which costs roughly $10,000 a year in additional interest on money you already had. A HELOC lets you keep the cheap mortgage and pay a market rate only on the new money.
If your existing rate is above current market rates, the calculus flips. A cash-out refinance lets you take the money and improve the rate on everything at once. Run both scenarios through the refinance calculator, entering the cash-out amount, to see the total cost difference rather than guessing.
#Rate structure and risk
Cash-out refinances are typically fixed-rate. You know the payment for thirty years. Cash-out pricing usually carries a small premium over a rate-and-term refinance — commonly a quarter point — because the lender is taking on more exposure.
HELOCs are almost always variable, priced as prime plus a margin. That means your payment moves with the policy rate. In a rising-rate environment a HELOC that looked cheap at drawdown can become uncomfortable. Many HELOCs also have an interest-only draw period, typically ten years, after which the loan amortises and the payment jumps sharply — a shock that catches a lot of borrowers.
#Upfront costs
Cash-out refinance closing costs run 2% to 5% of the entire new loan, not just the cash you take. On a $370,000 loan that is $7,400 to $18,500, which is a lot to pay for access to $60,000.
HELOC costs are far lower — often a few hundred dollars, sometimes nothing, occasionally with an annual fee. Some lenders waive costs entirely if you keep the line open for three years.
This asymmetry matters enormously for smaller borrowing needs. Below roughly $50,000, closing costs alone usually make a cash-out refinance the worse option unless you were refinancing anyway.
#Flexibility
A HELOC is a credit line. Draw $12,000 for a kitchen, repay it, draw $20,000 two years later for a roof. You pay interest only on what is outstanding.
A cash-out refinance is a single lump sum. If you take $60,000 and only spend $35,000, you are paying interest on $25,000 sitting in a savings account earning less.
For staged projects, uncertain amounts, or a standby emergency facility, the HELOC's flexibility is worth real money.
#A quick decision framework
Choose a cash-out refinance when: your current rate is at or above market, you need a large lump sum at once, you want payment certainty for the long term, and you were considering refinancing anyway.
Choose a HELOC when: your current mortgage rate is meaningfully below market, you need a smaller or uncertain amount, you want to draw in stages, or you want a standby facility you may never use.
#What both have in common
Both convert unsecured need into secured debt, which means your house is the collateral. That lowers the rate substantially and raises the stakes correspondingly. Using home equity to clear credit cards only works if the spending behaviour that created them has changed — otherwise you have moved the balance and kept the habit, and the next round of cards is secured by nothing while your equity is gone.
Before either, check whether the debt you are trying to clear is better attacked directly. The debt payoff calculator will show you what an aggressive repayment plan achieves without putting the house up.
Frequently asked questions
Which has the lower interest rate, a HELOC or a cash-out refinance?
Cash-out refinance rates are usually lower on paper because they are first-lien and fixed. But the comparison is misleading: the refinance rate applies to your whole balance while the HELOC rate applies only to what you draw. If your existing mortgage is well below market, the HELOC almost always costs less in total.
Is the interest tax deductible?
In the US, interest on home equity borrowing is deductible only when the funds are used to buy, build or substantially improve the home securing the loan, and only if you itemise. Using the money for debt consolidation or tuition does not qualify. Confirm with a tax professional.
How much equity do I need?
Most lenders require you to retain at least 20% equity after borrowing, so a combined loan-to-value of 80%. Some allow 85% or higher at a rate premium. VA cash-out refinances can go to 90% or more for eligible borrowers.
