HELOC vs Cash Out Refinance: How to Decide
Compare a second lien HELOC with a cash out refinance: what happens to your first mortgage rate, total interest, closing costs, payment structure and timing.
Updated 2026-08-21| Applies to: Homeowners with equity deciding how to fund a renovation, payoff, purchase or investment.
The short answer
A cash out refinance replaces your first mortgage with a larger one, so your entire balance moves to today's rate. A HELOC leaves the first mortgage alone and adds a second lien on only the amount you draw. If your current first mortgage rate is well below market, a HELOC usually preserves more value. If your current rate is at or above market, or you want one fixed payment, cash out can be the cleaner answer.
The question that decides it
What is the rate on your current first mortgage compared with today's market? If you hold a rate several points below current pricing, moving the whole balance to refinance the loan can cost far more in interest than borrowing a smaller amount at a higher rate on a second lien.
Comparison
| Factor | HELOC | Cash out refinance |
|---|---|---|
| First mortgage | Untouched | Replaced |
| Rate applies to | Only the drawn balance | The entire new loan amount |
| Rate type | Usually variable | Usually fixed |
| Closing costs | Often lower | Typically full first mortgage costs |
| Draw flexibility | Reusable during the draw period | One time at closing |
Run the comparison on total interest, not payment
The honest comparison is the total interest you expect to pay over the period you will actually hold the debt, plus closing costs, not just which monthly payment looks smaller. A short horizon favors the line. A long horizon with a large balance often favors a fixed structure.
When cash out still wins
- Your existing rate is at or above current market pricing
- You want a single fixed payment instead of managing a line
- You need a large amount that would push a second lien pricing higher
- You are also removing mortgage insurance or changing loan term

Common mistakes to avoid
- Refinancing a very low first mortgage rate to access a modest amount of cash
- Comparing an interest only HELOC payment with a fully amortizing refinance payment as if they were the same
- Forgetting that the HELOC rate can move while a fixed refinance cannot
