What is a cash-out refinance?

A cash-out refinance is a mortgage refinance where you borrow more than you currently owe and pocket the difference. Your existing mortgage is paid off entirely and replaced with a single new loan — typically at a fixed rate — for a larger amount.

For example: if your home is worth $500,000 and your current mortgage balance is $250,000, you might refinance into a new $350,000 mortgage. After paying off the old loan, you receive $100,000 in cash (minus closing costs).

Because it replaces your primary mortgage, a cash-out refi affects the rate on your entire outstanding balance — not just the new money you're borrowing. Closing costs typically run 2–5% of the new loan amount, which can add up to several thousand dollars on a large loan.

What is a HELOC?

A HELOC (Home Equity Line of Credit) is a revolving credit line secured by your home that sits as a second lien — your existing first mortgage stays completely in place. You can draw funds during the draw period (often 10 years), repay what you've used, and draw again, paying interest only on the outstanding balance.

Most lenders allow you to borrow up to 85% of your home's value minus your existing mortgage balance. HELOC rates are typically variable, tied to an index like the prime rate, so your payment can fluctuate. Closing costs are usually much lower than a cash-out refi — often minimal or waived entirely for smaller lines.

The key advantage of a HELOC is that it leaves your first mortgage untouched. If you locked in a low rate on that loan, you keep it. You only take on the HELOC rate for the incremental dollars you borrow.

Monthly payments One fixed payment (P&I) Interest-only on drawn balance during draw period
Best for Borrowers with a high existing rate who also want cash, or who want one simple fixed payment Borrowers with a low existing rate, or those needing flexible access to funds over time

When a cash-out refinance wins

A cash-out refinance makes the most sense in a few specific scenarios:

  • Your current mortgage rate is high. If today's prevailing rates are near or below what you're already paying, refinancing the full balance at a lower rate while pulling out cash can be a net win — you improve your overall cost of debt at the same time you access equity.
  • You want one single, predictable payment. A cash-out refi consolidates everything into a single monthly obligation at a fixed rate, which simplifies budgeting and eliminates the risk of a rising variable rate on your equity product.
  • You need a large lump sum. For major one-time expenses — a full home renovation, paying off high-interest debt, or funding a business — receiving the entire amount at closing can be more efficient than managing a revolving draw.
  • You also want to shorten (or lengthen) your term. A refi is the only way to change your loan term at the same time you access equity.

When a HELOC wins

A HELOC is generally the stronger choice when:

  • You have a low first-mortgage rate you want to keep. This is the most common reason homeowners choose a HELOC today. If you refinanced or purchased during a period of historically low rates, replacing your entire mortgage balance at a higher current rate to get cash would likely cost far more than opening a HELOC at the same rate for just the incremental amount.
  • You need flexible, ongoing access to funds. A revolving line is ideal for phased home renovations, tuition payments spread over years, or business expenses where you don't know the final total upfront.
  • You want to minimize upfront costs. With typically low or no closing costs, a HELOC makes sense when you want to access equity without paying thousands in origination fees.
  • You plan to repay quickly. Because a HELOC charges interest only on what you draw, paying down the balance before the repayment period begins limits your total cost — especially if the variable rate rises.

HELOCs are also often used alongside other debt-reduction strategies. Learn more in our guide to debt consolidation options.

The rate-lock test: Before choosing between these two products, ask yourself — "Would I refinance my entire first mortgage today even without needing cash?" If yes, a cash-out refi may make sense. If no, a HELOC is likely the better tool. Never give up a low first-mortgage rate to access equity if a second-lien product can do the job.

Frequently asked questions

It depends on your situation. A HELOC typically has lower upfront closing costs (often $0–$500 vs. 2–5% of the loan for a cash-out refi). However, HELOCs usually carry variable rates that can rise over time, while a cash-out refi locks in a fixed rate. If you plan to use the full amount immediately and want payment certainty, the total cost of a cash-out refi may be comparable over the long run. If you only need funds periodically or in smaller amounts, a HELOC tends to be cheaper overall because you only pay interest on what you draw.
Often yes, but not always. Many HELOC lenders require a full appraisal to confirm your home's current value before approving the line. Some lenders use automated valuation models (AVMs) for lower-risk borrowers or smaller loan amounts, which can eliminate the need for an in-person appraisal and speed up the process. Ask your lender upfront which approach applies to your application.
Not with a standard cash-out refinance — it replaces your entire existing mortgage with a new loan at today's prevailing rates. If you currently have a low first-mortgage rate (for example, one locked in during 2020 or 2021), replacing it with a higher current rate on a larger balance could significantly increase your total interest costs. In that scenario, a HELOC or home equity loan is usually the better way to access equity because it leaves your existing mortgage untouched.
HELOC interest may be tax deductible when the funds are used to buy, build, or substantially improve the home that secures the loan — under the rules established by the Tax Cuts and Jobs Act of 2017. Interest on HELOC funds used for other purposes (such as debt consolidation or personal expenses) is generally not deductible. Tax rules can change and individual situations vary, so consult a qualified tax advisor before assuming deductibility.
