HELOC vs. Cash-Out Refinance: Which Borrowing Method Fits Your Situation
How a HELOC and a cash-out refinance differ
A HELOC (home equity line of credit) and a cash-out refinance both let you borrow against your home's equity, but they work in opposite ways. A cash-out refinance replaces your entire mortgage with a new, larger one and gives you the difference in cash upfront — you're done borrowing after that. A HELOC is a revolving credit line, like a credit card backed by your home, that you draw from as needed over time and pay back on a schedule the lender sets.
The choice between them depends on how much you need, how fast you need it, what interest rates look like right now, and whether you want one lump sum or ongoing access to money. Neither is universally better — they solve different problems.
Key Takeaways
- A cash-out refinance gives you all the money at once and locks in one interest rate for the life of the loan, while a HELOC lets you borrow in pieces and your rate may adjust over time.
- Cash-out refinance closing costs are higher upfront but spread across a 15- or 30-year loan, while HELOC costs are lower but you pay interest only on what you actually borrow.
- A HELOC makes sense if you need money gradually or aren't sure how much you'll need; a cash-out refinance works better if you need a large sum now and rates are favorable.
- Both put your home at risk if you can't repay, and both require you to have built equity — typically at least 15 to 20 percent of your home's value.
Cash-out refinance: one payment, one rate, all the money now
When you do a cash-out refinance, your lender pays off your current mortgage entirely and issues you a new mortgage for a larger amount. You receive the difference between the old loan and the new one as a check. If your home is worth $400,000 and you owe $250,000, and you refinance for $320,000, you walk away with $70,000 in cash.
The interest rate on that new mortgage is locked in for the full term — 15, 20, or 30 years, depending on what you choose. Your monthly payment covers principal and interest on the entire $320,000. Closing costs (appraisal, title search, underwriting, attorney fees) typically run 2 to 5 percent of the loan amount, but you can roll them into the new loan balance rather than paying them upfront.
A cash-out refinance makes sense when you need a large amount of money right now — to pay off high-interest debt, fund a major home repair, or cover a one-time expense — and when current mortgage rates are close to what you're paying now. If rates have dropped significantly since you took out your original mortgage, refinancing also lowers your monthly payment even after you borrow more.
HELOC: borrow what you need, when you need it
A HELOC works like a credit card. Your lender approves you for a maximum credit line — say, $100,000 — based on your home's equity and your credit score. You don't have to use it all at once. You draw money as you need it, and you pay interest only on what you've actually borrowed. If you draw $30,000 and pay it back before drawing again, you never pay interest on the unused $70,000.
Most HELOCs have a draw period (usually 5 to 10 years) when you can borrow and make interest-only payments, followed by a repayment period (usually 10 to 20 years) when you can no longer draw and must pay back what you owe in full. During the draw period, your interest rate is often variable, meaning it moves with the market — your payment can go up or down. Some lenders offer fixed-rate options on individual draws.
A HELOC is useful when you're not sure how much money you'll need, or when you need it in stages. Homeowners often use HELOCs for ongoing expenses like a kitchen renovation that happens in phases, or as a safety net for emergencies without committing to a large loan upfront.
Comparing costs and monthly payments
A cash-out refinance has higher upfront costs but simpler math after that. Closing costs are typically $5,000 to $15,000 on a $300,000 loan, but you amortize them over 15 or 30 years, so the real cost per month is small. Your monthly payment is fixed and predictable for the life of the loan.
A HELOC has lower or no upfront costs — many lenders charge no closing costs or only a small application fee — but you pay interest on every dollar you borrow. During the draw period, you might pay only interest, so your payment is lower, but you're not building equity. Once the repayment period starts, your payment jumps because you're now paying principal and interest, and the rate may have risen if it's variable.
The table below shows how costs and payments typically compare for a $50,000 need:
| Cash-Out Refinance | HELOC | |
|---|---|---|
| Upfront costs | $3,000–$5,000 (can be rolled into loan) | $0–$500 |
| Interest rate | Fixed for 15–30 years | Variable (usually); fixed options available |
| Monthly payment on $50,000 at 7% | ~$333 (30-year term) | ~$292 (interest-only during draw period); ~$583 (principal + interest during repayment) |
| Best for | One large expense now; favorable rates | Gradual or uncertain borrowing needs |
How rates and timing affect your choice
If mortgage rates have dropped since you took out your original loan, a cash-out refinance can lower your overall monthly payment even though you're borrowing more. If rates have risen, refinancing costs you more per month, so a HELOC might be cheaper in the short term because you only pay interest on what you draw.
Timing also matters. A cash-out refinance takes 30 to 45 days from application to closing. A HELOC can take 2 to 4 weeks, but you don't receive money immediately — you have to request it. If you need cash in the next week or two, neither is fast enough; you'd need to use a credit card or personal loan instead.
Consider also what happens if you don't use all the money. With a cash-out refinance, you're paying interest on the full amount whether you spend it or not. With a HELOC, unused credit costs you nothing.
Risk and what happens if you can't repay
Both a HELOC and a cash-out refinance are secured by your home, meaning your lender can foreclose if you stop paying. This makes them cheaper than unsecured loans like personal loans or credit cards, but it also means you're putting your home on the line.
With a cash-out refinance, you have one monthly payment for one loan. If you miss payments, foreclosure follows the same timeline as any mortgage default — typically 120 days of missed payments before formal proceedings begin, though this varies by state.
With a HELOC, you have two loans: your original mortgage and the HELOC sitting on top of it. If you default on the HELOC, the lender can foreclose, and so can your original mortgage lender if you fall behind on that payment. During a recession or market downturn, some lenders also freeze HELOCs, meaning you can no longer draw new money even if you're current on payments — this happened to many homeowners during the 2008 financial crisis.
Equity requirements and who qualifies
Both products require you to have built equity in your home. Most lenders want to see at least 15 to 20 percent equity before they'll approve a HELOC or cash-out refinance. If your home is worth $300,000 and you owe $270,000, you have $30,000 in equity (10 percent), which may not be enough.
Your credit score, debt-to-income ratio, and employment history also matter. Lenders typically want a credit score of 620 or higher for a cash-out refinance and 700 or higher for a HELOC, though these minimums vary. A cash-out refinance also requires a new appraisal, which costs $300 to $500 and takes 1 to 2 weeks.
If you have less than 15 percent equity, you may still refinance, but you'll pay a higher interest rate or be required to buy mortgage insurance, which adds to your monthly payment. A HELOC may not be available to you at all.
Frequently Asked Questions
Can I use a HELOC and a cash-out refinance at the same time?
Yes. Some homeowners refinance their primary mortgage and open a HELOC as a second lien on the same home. This lets you lock in a low rate on the refinance while keeping a flexible credit line for future needs. Your lender will consider both debts when calculating how much you can borrow.
What if interest rates drop after I do a cash-out refinance?
You can refinance again, but you'll pay closing costs a second time. If rates drop by 0.5 percent or more, a second refinance may make financial sense; if they drop by 0.25 percent, it usually doesn't. A HELOC's variable rate adjusts automatically, so you don't have this problem, but your payment can also go up if rates rise.
Do I have to pay back a HELOC if I sell my house?
Yes. When you sell, the proceeds go first to pay off your primary mortgage, then to pay off the HELOC balance, then to you. If the sale price doesn't cover both loans, you have to pay the difference out of pocket. With a cash-out refinance, there's only one mortgage to pay off, so the math is simpler.
Which one is better for paying off credit card debt?
A cash-out refinance is usually better if you have a large amount of high-interest credit card debt and can get a mortgage rate significantly lower than your card's rate. You get all the money at once, pay off the cards immediately, and lock in a fixed payment. A HELOC works if you're paying down cards gradually and want to avoid taking on new debt.
Can I deduct the interest on either one?
Mortgage interest, including interest on a cash-out refinance or HELOC, is deductible only if you itemize deductions on your tax return and the loan is secured by your primary or secondary home. The total mortgage debt across all loans on your home cannot exceed $750,000 for loans taken out after December 15, 2017. Consult a tax professional about your specific situation.
