A home equity line of credit (HELOC) is revolving credit line. It is also secured by the equity in your home, but instead of receiving a lump sum of cash as with the Home Equity Loan, you have the ability to make draws on your revolving line of credit account. You can then borrow and pay back money as you need it, up to the approved credit limit.
HELOCs usually have a variable interest rate, so your monthly payment will depend on current interest rates and the amount of the credit line being used.
