Q: I’m looking to tap into my home’s equity, possibly using a Home Equity Line of Credit. What are some of the advantages of choosing the HELOC option?
A: A Home Equity Line of Credit (HELOC) is an open credit line that is secured by the paid value of the borrower’s home. Homeowners can generally open a HELOC with up to 85% of their home’s equity, or the difference between what’s left on their home loan and the current value of it. A HELOC provides homeowners with a convenient way to use the equity in their home.
