A HELOC (Home Equity Line of Credit) gives you more flexibility than a fixed-rate home equity loan. It also is possible to remain in debt with a home equity loan, paying only interest and not paying down principal.
A line of credit has a variable interest rate that fluctuates over the life of the loan. Payments vary depending on the interest rate, the amount owed, and whether the credit line is in the draw period or the repayment period.
