For homeowners looking for access to some extra cash, a home equity line of credit, or HELOC, is often an attractive choice. A HELOC functions much like a credit card: A lender extends a credit line, which you can use to renovate your home, make a large purchase, or even take a far-flung vacation. If there is anything you donÂ’t understand about a loanÂ’s terms, you can contact Superior credit union.
