Does a HELOC replace my mortgage?

No — that's the main difference from a cash-out refinance. A HELOC sits behind your existing mortgage as a second lien, so your original loan stays exactly as it is.

Can I borrow again after paying down a HELOC?

Yes, during the draw period — that revolving flexibility is the defining feature. After the draw period ends, the line enters repayment and you pay the balance down.

HELOC or cash-out refinance — which is better?

It depends on your current mortgage, how much you need, and whether the need is ongoing. If you want to keep your mortgage and value flexibility, a HELOC often fits; for a single lump sum, a cash-out refinance may be better.

Second Mortgages Explained | MortgageQuote.com

What a second mortgage is

A second mortgage is a loan secured by your home that sits behind your existing first mortgage. Because it’s in second position, it’s repaid after the first mortgage if the home is ever sold or foreclosed, which is why second mortgages are structured around that added risk. Home equity loans and home equity lines of credit (HELOCs) are the most common forms of second mortgage.

Home equity loan vs. HELOC

A home equity loan gives you a lump sum that you repay over a set term, often at a fixed rate, functioning like a traditional installment loan in second position. A HELOC is a revolving line of credit you can draw on as needed during a draw period, more like a credit card secured by your home. Both let you access equity while keeping your first mortgage in place.

How it differs from a cash-out refinance

A second mortgage adds a new loan on top of your existing first mortgage, leaving that first loan untouched. A cash-out refinance instead replaces your first mortgage with a larger one. The key advantage of a second mortgage is preserving a first mortgage you want to keep, such as one with a favorable rate, while still tapping equity. The tradeoff is that you now have two payments.

Considerations

Because a second mortgage is secured by your home, it deserves the same care as any mortgage: understand the terms, the payment, and your ability to repay. It’s a way to access equity for goals like renovations or consolidating debt, while keeping your first mortgage intact. A licensed loan originator can compare a second mortgage against a cash-out refinance and help you decide which structure fits your situation.
