Quick answer
When does HELOC beat cash-out refinance?
A HELOC or home equity loan usually deserves the first look when the borrower has an older low-rate first mortgage and only needs a smaller or phased amount. A cash-out refinance deserves a fresh quote when the borrowing need is large, the new rate is close to the old rate, and the borrower wants one fixed long-term payment. The tax question is separate: interest is generally tied to whether proceeds buy, build, or substantially improve the home securing the debt.
HELOC
Variable; often Prime + margin. Planning benchmark here: 7.75% if Prime is 6.75% and margin is 1.00%.
Best for: Flexible or phased borrowing when you want to preserve an older low first-mortgage rate.
Watch: Variable-rate risk, draw-period reset, interest-only traps, annual fees, and collateral risk.
Home equity loan
Usually fixed second mortgage. Planning range here: 8.25%-9.75% for strong-credit examples.
Best for: One known lump-sum need where fixed payment certainty matters more than draw flexibility.
Watch: Higher second-lien rate, separate payment, closing costs, and less flexibility after funds are disbursed.
Cash-out refinance
New first mortgage; planning benchmark here: about 7.03% using PMMS + 0.50 percentage point.
Best for: Large long-term borrowing when the new rate is close to or below your existing mortgage rate.
Watch: Replacing a low first mortgage, resetting amortization, 2%-5% closing costs, and slower break-even.

Decision checklist before applying
- If your current first mortgage is far below today rates, price a HELOC or home equity loan before replacing the whole loan.
- If the cash need is small or uncertain, a HELOC can be cheaper to open and easier to draw gradually.
- If the cash need is large, fixed, and long-term, compare a home equity loan with a cash-out refinance using total interest and closing costs.
- If proceeds are not used to buy, build, or substantially improve the home securing the loan, do not assume the interest is deductible.
- If the reason is unsecured debt consolidation, treat foreclosure risk as the main downside, not just the APR spread.

Frequently asked questions
HELOC vs cash-out refinance: which is cheaper?▼
It depends on cash need, current first-mortgage rate, fees, and repayment time. A HELOC often wins for smaller or phased borrowing because it preserves the first mortgage and can have lower upfront costs. A cash-out refinance can win for larger long-term borrowing when the new first-mortgage rate is close to or below the existing rate. In this May 2026 planning example, cash-out refi is about 7.03% using PMMS plus 0.50 percentage point, while a HELOC at Prime + 1.00% is about 7.75%.
How does a HELOC interest rate work?▼
A HELOC is usually a variable-rate line of credit secured by the home. Many HELOCs are priced as Prime Rate plus a lender margin. This page uses a 6.75% Prime benchmark and a 1.00 percentage point example margin, or about 7.75%, for planning only. The borrower's actual APR can change with credit profile, LTV, lender margin, fees, introductory pricing, and future Prime Rate moves.
What about home equity loans?▼
A home equity loan is a lump-sum second mortgage, often with a fixed rate and fixed payment. It can be cleaner than a HELOC when the borrower knows the exact amount needed and wants payment certainty. This page models a strong-credit planning range of about 8.25% to 9.75%, but borrowers should compare written quotes, fees, prepayment terms, and total interest.
What are typical HELOC closing costs?▼
HELOC costs vary by lender and state. A borrower may see application, appraisal, title, recording, annual, inactivity, or early-termination fees. Some lenders waive certain upfront costs but recapture them if the line closes early. Compare APR, margin, draw period, repayment period, annual fees, and early-closure language before calling a HELOC low-cost.
Should I tap home equity for debt consolidation?▼
Be careful. A home equity loan or HELOC turns unsecured debt into debt secured by the home. The APR can be lower than a credit card or personal loan, but missed payments can put the house at risk. A safer comparison includes payment amount, payoff discipline, income stability, emergency cash, and whether the borrower will avoid rebuilding the same unsecured balances.
Is home equity or cash-out refinance interest tax deductible?▼
IRS Publication 936 says interest from a home equity loan, HELOC, or similar secured loan is not deductible if the proceeds were not used to buy, build, or substantially improve a qualified home. The mortgage-interest cap, itemizing, loan date, and use of proceeds matter, so borrowers should track how funds are used and consult a qualified tax professional for their own return.
Can I get a HELOC with imperfect credit?▼
Possibly, but pricing and approval are lender-specific. Lower credit scores usually mean lower combined LTV limits, higher margins over Prime, stricter income documentation, or denial. Compare whether waiting to improve credit, reducing card utilization, using a smaller personal loan, or delaying a project creates a safer outcome than taking a high-cost second lien.
When should I not borrow against home equity?▼
Avoid or slow down when income is unstable, emergency reserves are thin, the home could be sold soon, the purpose is a depreciating purchase, the terms include a balloon or confusing reset, or the lender/contractor is pressuring a fast signature. Because the home is collateral, the risk analysis should start with foreclosure exposure, not only monthly payment.
