What each option does
A home equity line of credit (HELOC) is a separate, revolving line secured by your home. You draw funds during a draw period, then repay over a set term. A cash-out refinance, by contrast, replaces your existing mortgage with a new, larger loan and you receive the difference at closing.
Because a HELOC sits behind your existing mortgage, your first mortgage and rate are unchanged. A cash-out refinance resets the rate, term, and balance of your primary loan.
Rate, term, and payment differences
HELOC rates are often variable and may adjust with market conditions during the draw period. A cash-out refinance typically uses a fixed rate (or a defined adjustable structure) for the full term.
If your existing first-mortgage rate is materially lower than current rates, replacing it through a cash-out refinance may significantly increase the cost of the underlying balance — not just the new equity portion.
Closing costs and access
HELOCs often have lower upfront costs than a refinance, though specific fees vary by lender. A cash-out refinance generally has full closing costs similar to a purchase mortgage.
HELOCs offer flexible access — you draw only what you need. Cash-out refinances deliver a single lump sum at closing.
When each may fit
A HELOC may fit phased projects or unpredictable expenses where flexibility matters. A cash-out refinance may fit a known, large need when current rates make replacing the underlying mortgage reasonable.
