Cash-out refinance vs HELOC is the fork most homeowners hit once they decide to use their equity. One replaces the mortgage you already have; the other sits alongside it. This guide compares the two on structure, cost, and risk so you can see which questions to ask. It is educational only, and both options are secured by your home — missing payments on either can put the property at risk.
How each option is structured
- A cash-out refinance pays off your existing mortgage with a larger new one and returns the difference to you. You end up with a single, bigger first mortgage.
- A HELOC leaves the first mortgage untouched and adds a revolving line behind it. You draw only what you need, when you need it.
A home equity loan is a third variant — a fixed lump sum in second position. See home equity loan vs HELOC and the home equity borrowing hub.
Rate structure: fixed vs. variable
Cash-out refinances are usually fixed-rate, giving one predictable payment for the life of the loan. HELOCs are usually variable, tied to an index, so the payment moves. That is the core fixed vs variable equity borrowing trade-off: certainty against flexibility.
The catch on the refinance side is that you re-price your entire mortgage, not just the cash you take. If your existing rate is low, replacing it can cost more overall even when the new rate looks reasonable on its own.
Closing costs and what you keep
Refinancing a first mortgage typically carries full closing costs — origination, title, recording, and a formal appraisal — calculated on the whole loan amount. HELOC costs are usually lighter, and some companies advertise low or waived upfront fees, though ongoing fees may apply. See HELOC closing costs and fees for that side.
Cost is only half the question. The other half is what you give up: your current rate, your remaining term, and any features attached to the existing loan. For that maths, see when refinancing makes sense and rate-and-term vs cash-out refinance.
First lien vs second lien consequences
A cash-out refinance keeps everything in first lien position. A HELOC creates a second lien that sits behind the mortgage in priority. Second position generally carries more risk for the company, which is part of why pricing differs — and it can complicate a future refinance, since the second-lien holder must agree to stay behind the new first mortgage.
Which situations suit each
- One large, known, one-time cost and a mortgage you would refinance anyway → the refinance often reads better.
- Costs spread over time, such as phased renovations → the HELOC's draw structure fits.
- A first mortgage you want to keep untouched → a second-lien product avoids re-pricing it.
- Uncertain need → a line you may never fully draw costs less to leave open.

Structures differ enough that a side-by-side is worth the effort. Browse finance companies and compare advertised offers, then confirm rates, costs, and lien position with each company.
Frequently asked questions
Is a cash-out refinance cheaper than a HELOC?
Not automatically. A refinance may carry a lower rate but re-prices your whole mortgage and usually costs more upfront. A HELOC keeps the existing mortgage but is typically variable. Compare total cost over the years you actually plan to hold the debt.
Can I have a HELOC and a mortgage at the same time?
Yes — that is the normal arrangement. The HELOC sits in second lien position behind the first mortgage. Both are secured by the home, and the combined balances are limited by the company's combined loan-to-value ceiling.
Does a HELOC make refinancing harder later?
It can. The HELOC holder generally has to sign a subordination agreement to remain in second position behind a new first mortgage. Many companies accommodate this, but it adds a step, a possible fee, and some processing time.
