Key insights

HELOC = variable rate exposure

HELOCs are typically Prime + a margin (currently ~8-10%). When the Fed raises rates, your payment goes up. Stress-test for 2-3 percentage points higher.

Cash-out refi resets your mortgage clock

Replacing a 15-years-in mortgage with a fresh 30-year adds 15 years of interest payments. Total lifetime cost can rise even with a lower rate — keep paying the old monthly.

Lower closing costs

HELOCs typically have $0-500 in closing costs vs $5K-$15K for a cash-out refi. Big advantage if you might not stay long.

Recommended actions(2)

Verify the rates lender will actually offer you

High priority

These calculations assume rate quotes. Real underwriting uses your credit score, LTV, and reserves. Pre-qualify both products before committing to either path.

Stress-test the HELOC for higher rates

Medium priority

Add 2-3 percentage points to the HELOC rate and re-run. If you can't comfortably handle the payment at that level, choose the refi for predictability.
