A HELOC, or Home Equity Line of Credit, is a type of revolving credit that lets homeowners borrow against the equity in their property. The available limit is typically based on the home’s value minus any outstanding mortgage. Borrowers can draw funds as needed, similar to a credit card and pay interest only on the amount they use. They have also become an attractive asset class for investors because they’re secured by real estate and generate stable, interest-based returns.
