HELOC vs. Cash-Out Refinance: The 2026 Comparison
On this page
Two ways to pull equity. Very different long-term math.
Both let you tap the equity in your primary home. HELOC keeps your existing first mortgage untouched and adds a variable-rate line of credit. Cash-out refinance replaces your first mortgage with a bigger fixed-rate loan.
Why this makes sense right now
HELOC originations hit 1.4M in 2024 per Attom Data. Cash-out refinance volume: 890K, down 22% from 2020's peak because most homeowners have below-market first mortgages worth preserving.
The critical variable: what's your current mortgage rate? If under 5%, HELOC dominates. If over 7%, cash-out refi may win.
The layout — head-to-head
Existing mortgage impact
- HELOC: untouched
- Cash-out refi: replaced
Rate 2026 typical
- HELOC: 8.25%-9.75% variable
- Cash-out refi: 6.5%-7.5% fixed
Closing time
- HELOC: 30-45 days
- Cash-out refi: 45-60 days
Closing costs
- HELOC: $500-$2,000
- Cash-out refi: $3K-$8K + standard refinance costs
Payment structure
- HELOC: interest-only during draw
- Cash-out refi: standard P+I
Amortization impact
- HELOC: no reset
- Cash-out refi: fresh 30-year clock
Financing math
Scenario: $150K equity draw for ADU build. Existing mortgage: $300K balance at 4.5%.
HELOC at 8.75%:
- $150K × 8.75% = $1,090/month interest
- Existing mortgage stays at 4.5%
- Total: existing P+I + $1,090
Cash-out refi at 7% (new $450K mortgage at 7%):
- $450K at 7% for 30 years = $3,000/month P+I
- Replaces existing 4.5% loan
- Total: $3,000/month
If existing rate is 4.5%, keeping it via HELOC is dramatically cheaper. If existing rate is 7.5%, cash-out refi becomes competitive.
Choose HELOC if...
- Existing mortgage rate is below current market
- Draw amount is under $180K
- Fast close matters
- You want to preserve the existing loan structure
Choose cash-out refi if...
- Existing mortgage rate is above current market
- Draw amount is $200K+
- Fixed-rate certainty matters
- You want a single consolidated payment
The quiet part.
The cash-out refinance was the standard equity-extraction tool for 30 years because 30-year fixed rates were competitive with everything else. That world ended in 2022 when 3% mortgages became sacred. Now the question isn't which is better — it's whether the existing mortgage rate is worth preserving.
Every homeowner with a sub-5% mortgage should keep it. HELOC is the only sensible way to tap equity while keeping that rate. Cash-out refi makes sense only if the existing rate is worse than the new one.
