Home equity lines of credit (HELOCs) allow homeowners to access funds needed for home renovations, college tuition, medical bills, or other unexpected expenses. Since most people have just one home, HELOCs are usually taken out on a borrower’s primary residence. However, it’s possible to take out a HELOC on an investment property. The catch is that HELOCs on investment properties come with stricter requirements, aren’t widely available, and are hard to qualify for.
