If you need to tap home equity for renovations, debt consolidation, or other major expenses, you have two primary options: a home equity line of credit (HELOC) or a cash-out refinance. Both let you borrow against your home's equity, but they work very differently — and the right choice depends on how much you need, when you need it, and your current mortgage rate.
HELOC: A revolving line of credit secured by your home. You are approved for a maximum amount (say $80,000) and draw from it as needed during a "draw period" (typically 10 years), paying interest only on what you use. After the draw period, you enter a repayment phase (10–20 years) where you pay back principal plus interest. HELOCs typically carry variable interest rates tied to the prime rate.
Cash-out refinance: You replace your existing mortgage with a new, larger mortgage and receive the difference in cash. If you owe $250,000 and refinance for $330,000, you receive $80,000 at closing (minus closing costs). The entire amount — old balance plus new cash — is rolled into a single fixed-rate mortgage.
| Feature | HELOC | Cash-Out Refinance |
|---|---|---|
| Interest Rate | Variable (prime + 0.5–2%), currently ~8.5–9.5% | Fixed, currently ~6.5–7.0% |
| Closing Costs | $0–$2,000 (often waived) | $5,000–$12,000 (2–3% of loan) |
| Access to Funds | Draw as needed over 10 years | Lump sum at closing |
| Repayment | Interest-only during draw, then P+I | Fixed monthly P+I |
| Impact on Current Mortgage | None — your first mortgage stays | Replaces your existing mortgage |
| Tax Deductibility | Interest deductible if used for home improvements | Same — improvements only |
| Best For | Ongoing projects, flexibility, keeping a low first mortgage rate | Large one-time need, consolidating debt into one payment |
This is the deciding factor for most homeowners in 2026. If your current mortgage rate is below 5% (locked in during 2020–2021), a cash-out refinance would replace that low rate with today's 6.5%+ rate on your entire balance — costing you thousands per year in additional interest on money you already owed. In this case, a HELOC is almost always the better choice because it leaves your favorable first mortgage untouched.
If your current rate is above 6.5%, a cash-out refinance makes more sense because you are simultaneously lowering your existing rate while accessing equity — getting both benefits in one transaction.
Example: You have a $300,000 mortgage at 3.5% and need $60,000 for a renovation. A cash-out refi at 6.5% on $360,000 increases your monthly P&I from $1,347 to $2,275 — an increase of $928/month, of which only $379 is attributable to the new $60,000. A HELOC for $60,000 at 9% costs approximately $540/month interest-only — higher on the HELOC portion, but your first mortgage stays at $1,347. Total: $1,887/month vs $2,275. The HELOC saves $388/month by preserving your low first mortgage rate.
Choose a HELOC if: your current mortgage rate is below today's rates, you need flexibility to draw funds over time (phased renovation, ongoing expenses), you want low or no closing costs, or you need a smaller amount ($10,000–$50,000) where refinance closing costs would be disproportionate.
Choose a cash-out refinance if: your current mortgage rate is at or above today's rates, you need a large lump sum, you want payment predictability (fixed rate vs variable HELOC rate), or you want to consolidate the HELOC and mortgage into one payment for simplicity.
HELOC rates are variable, typically tied to the prime rate plus a margin (0.5–2%). If the Federal Reserve raises rates, your HELOC payment increases. This happened dramatically in 2022–2023 when HELOC rates jumped from ~4% to ~9% within 18 months. Borrowers who took HELOCs at 4% expecting to pay $333/month on $80,000 suddenly faced $600/month payments.
Some lenders offer fixed-rate HELOC options (you can lock portions of your balance at a fixed rate). These typically carry rates 0.5–1% higher than the variable rate but eliminate the risk of payment increases. If you are borrowing a large amount, the rate lock is often worth the premium.
Under current tax law (Tax Cuts and Jobs Act, as amended), interest on home equity debt is deductible only if the funds are used to buy, build, or substantially improve the home securing the loan. This applies to both HELOCs and cash-out refinances. Interest on home equity used for debt consolidation, education, medical expenses, or other non-home-improvement purposes is not deductible.
If you are borrowing $80,000 for a kitchen renovation, the interest is deductible (subject to the $750,000 total mortgage debt cap). If you are using $80,000 to pay off credit cards, the interest is not deductible regardless of whether you use a HELOC or cash-out refi.
| Scenario | Current Mortgage Rate | Amount Needed | Purpose | Best Option |
|---|---|---|---|---|
| Renovation, low existing rate | 3.5% | $50,000 | Kitchen remodel | HELOC (preserves low first mortgage) |
| Renovation, high existing rate | 7.5% | $60,000 | Addition + bathroom | Cash-out refi (lowers rate + accesses equity) |
| Debt consolidation | 3.5% | $30,000 | Credit card payoff | HELOC (but proceed with caution — converting unsecured to secured debt) |
| Emergency fund access | Any | $20,000–$50,000 | Available if needed | HELOC (draw only what you need, pay interest only on usage) |
| Large project, want fixed payments | 6%+ | $100,000+ | Major renovation | Cash-out refi (predictable fixed payment, potentially lower rate) |
