Second mortgages are a popular way for homeowners to tap into the equity of their property and gain access to additional funds. However, the term "second mortgage" can be a bit confusing for some people. That's why it's helpful to know some synonyms for this type of loan. Some alternative phrases include "home equity loan", "second lien loan", "cash-out refinance", and "home equity line of credit (HELOC)". Each of these terms describes a slightly different type of loan or borrowing arrangement, so it's important to understand the differences between them and choose the one that best fits your financial needs and goals.
