Cash-out refinance vs. second mortgage vs. HELOC

Educational guide · Updated 2026

Once you've built equity in your home, there are three common ways to turn some of it into cash: a cash-out refinance, a second mortgage (home equity loan), or a HELOC. They sound similar but work quite differently, and the right choice depends on your existing rate, how much you need, and how you'll use it.

Which one fits when

You have $120,000 in equity and need funds: Cash-out refi makes sense if current rates are near your existing rate — you replace your whole mortgage and get cash. HELOC is better for ongoing needs like a renovation where you draw funds over time. A second mortgage (home equity loan) is best for a one-time lump sum at a fixed rate when you don't want to reset your first mortgage.

Cash-out refinance

You replace your existing mortgage with a new, larger one and take the difference in cash. You end up with a single loan at a single rate. This can make sense if current rates are at or below your existing rate — but if your current mortgage has a low rate, refinancing the whole balance to access equity means giving up that low rate on your entire loan, which is often a poor trade.

Second mortgage (home equity loan)

This leaves your first mortgage untouched and adds a second loan on top, secured by your equity. You get a lump sum at a fixed rate and pay it back on its own schedule. Because your original mortgage stays in place, this is attractive when you have a low first-mortgage rate you don't want to disturb. The second loan's rate is typically higher than a first mortgage's.

HELOC (home equity line of credit)

A HELOC is also a second lien, but instead of a lump sum it's a revolving line of credit you draw from as needed, like a credit card secured by your home. Rates are usually variable, and you typically have a "draw period" where you can borrow, followed by a repayment period. This suits ongoing or uncertain expenses — a renovation that bills in stages, for example — more than a single large one-time need.

How to choose

If current rates are favorable and you want everything in one loan, a cash-out refinance can work. If you have a low first-mortgage rate worth protecting and need a fixed lump sum, a second mortgage usually beats disturbing it. If your need is flexible or spread over time, a HELOC's draw structure fits. In every case, you're borrowing against your home — so the stakes of repayment are higher than with unsecured debt.

Frequently asked questions

Does a cash-out refinance reset my 30-year clock?

Yes. If you refinance into a new 30-year loan, your payoff timeline resets. You can refinance into a shorter term (15 or 20 years) to avoid this.

Is HELOC interest tax deductible?

It may be, if the funds are used to buy, build, or substantially improve the home. Consult a tax professional for your specific situation.

How much equity can I cash out?

Most lenders allow you to cash out up to 80% of your home's value (leaving 20% equity). VA loans may allow up to 90%.
