Both a HELOC and a cash-out refinance let you access home equity, but they are structurally very different. A cash-out refinance replaces your existing mortgage with a new, larger one â you get the difference in cash and now have one loan at a new rate. A HELOC adds a second revolving line of credit against your equity while leaving your existing mortgage in place. Which changes your first mortgage, how the rate is structured, and what you pay in closing costs differ materially between the two.
Banks, credit unions, and home equity lenders
Revolving second lien â draw what you need, when you need it, without touching your first mortgage.
Pros
Mortgage lenders and banks
Replace your first mortgage with a larger one and receive the difference in cash â single loan, potentially fixed rate.
Pros
Pick HELOC (Home Equity Line of Credit) if: Homeowners who want flexible, on-demand access to equity over time (e.g., ongoing home improvements or a reserve) without replacing their existing first mortgage.
Pick Cash-Out Refinance if: Homeowners who want a large lump sum at a fixed rate and are comfortable replacing their existing mortgage (especially when current rates are at or below their existing rate).

A HELOC is a revolving second lien â it gives you a credit line against your home equity while leaving your existing first mortgage completely unchanged. A cash-out refinance replaces your existing mortgage entirely with a new, larger loan and pays you the difference at closing. The core difference: a HELOC adds a second lien; a cash-out refi changes your first. If your current mortgage rate is below market rates, a cash-out refi raises your rate on your full balance.

No. A HELOC is a separate second lien â your original mortgage rate, term, and monthly payment stay completely intact. You draw from the HELOC as needed during the draw period (typically 10 years) and pay interest only on the drawn balance. The HELOC adds a second monthly payment when you have a balance, but your first mortgage is unaffected. A cash-out refinance, by contrast, retires and replaces your first mortgage entirely.

This is an educational comparison, not financial advice. Structurally: when current market mortgage rates are higher than your existing first-mortgage rate, a cash-out refinance forces you to trade your lower rate for a higher one on your full balance. A HELOC lets you access equity without touching your first mortgage, preserving your existing rate. The HELOC rate is usually variable (tied to prime), so it carries its own rate-change risk.
