Home equity has quietly become the largest source of wealth for most American homeowners — and the question of how to access it is among the most consequential financial decisions a homeowner can make. The two main tools, HELOCs and cash-out refinances, look superficially similar but behave very differently in ways that matter to your bottom line.
The structural difference
HELOC (Home Equity Line of Credit) — A revolving credit line secured by your home. You borrow as needed up to a limit, repay, and re-borrow. Variable interest rate. Typically a 5–10 year draw period followed by a 10–20 year repayment period. Your existing mortgage stays in place; the HELOC is a second lien.
Cash-out refinance — Replaces your existing mortgage with a new larger one. You receive the difference in cash. Fixed interest rate. Resets the loan term (typically 15 or 30 years). Closing costs of 2–3% of the new loan amount.
The numbers, current
| Factor | HELOC | Cash-out refi |
|---|---|---|
| Current rates (740+ FICO) | 7.5% – 9.5% variable | 6.5% – 7.5% fixed |
| Closing costs | $0 – $2,000 | 2–3% of new loan |
| Time to close | 2–6 weeks | 30–45 days |
| Repayment | Interest-only during draw, then P&I | P&I from day one |
| Tax deductibility | Interest deductible if used for home improvement | Same rules apply |
| Affects current mortgage rate? | No | Yes — new rate replaces old |
When HELOC wins
Your existing mortgage rate is below current market. If you have a 3.5% mortgage from 2021, you do not want to refinance into a 6.5% mortgage. HELOC lets you tap equity without touching the favorable existing rate.
You want flexibility on draw timing. Renovations, tuition payments over multiple years, or business funding that comes in tranches — HELOC lets you draw as needed and only pay interest on what you've drawn.
You expect to repay quickly. If your need is short-term (under 3 years), HELOC's lower closing costs make the math favor it even at higher rates.
You want a credit safety net. Many homeowners open a HELOC and never draw on it, treating it as an emergency reserve. The line stays open, available if needed.
When cash-out refinance wins
Your existing mortgage rate is at or above current market. If your current mortgage is at 8% and you can refinance into 7%, the cash-out refi gets you cash and lowers your rate.
You want fixed-rate certainty. HELOCs are variable. If rates rise, your HELOC payment rises. Cash-out refi locks in a fixed rate for 30 years.
You're borrowing a large amount over a long time. A $200,000 borrow over 30 years at fixed 6.75% is meaningfully cheaper than the same borrow at variable 8.5% via HELOC, even after closing costs.
You want to consolidate everything. Cash-out refi simplifies your housing finance to one loan, one payment.
The math, with real numbers
Take a homeowner with a $300,000 balance on a 4.5% mortgage and $400,000 in equity. They want $100,000 for a renovation.
HELOC at 8.25% variable: Interest-only payment of roughly $688/month during draw period. If rates stay flat, lifetime cost on a 10-year payoff is approximately $42,000 in interest.
Cash-out refi to $400,000 at 6.75% fixed: New monthly payment $2,594 (vs. existing $1,520 — an increase of $1,074/month). Closing costs $8,000. The cash-out portion ($100,000) costs roughly $133,000 in additional lifetime interest plus $8,000 closing.
The HELOC wins for this homeowner — by a wide margin — because their existing 4.5% mortgage is far below current market rates. Refinancing the entire loan to 6.75% would cost them more than they gain in cash.

Frequently asked questions
Is a HELOC or cash-out refinance better in 2026?
Depends on your existing mortgage rate. If below current market (sub-6%), HELOC is almost always better. If at or above current market, cash-out refi can win.
What credit score do I need for a HELOC?
Most lenders require 680+ for the best rates, with some accepting 620+. Equity matters more than credit score for HELOC underwriting.
Can I deduct HELOC interest on taxes?
Only if the funds are used for home improvement. The 2017 Tax Cuts and Jobs Act eliminated the general home-equity-interest deduction for non-improvement uses.
How much equity can I borrow?
Most lenders allow combined LTV (existing mortgage plus HELOC) up to 80–85% of home value. Some go to 90% for excellent credit.
