What is a HELOC loan?

stands for Home equity line of credit (H.E.L.O.C.)

HELOC rates are generally a little higher than rates on first mortgages, but they can still be worth it if you're looking to tap into your home's equity without having to take on a new rate on your main mortgage. As with other types of mortgages, you'll want to shop around and get multiple rate quotes to find the best HELOC lenders.
