HELOC vs. Cash-Out Refinance: The 2026 Comparison

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.
