A home equity loan disburses the entire amount of the loan when you take out the loan, so you accrue interest on the entire amount from the start of the loan. A home equity line of credit disburses funds as you request them so that instead of accruing interest on the entire line of credit, you only accrue interest on the amount in use.
Home equity loans can have a fixed interest rate or a variable interest rate. Home equity lines of credit almost exclusively have adjustable interest rates.
With a home equity loan, make monthly payments that include interest and principal so that you will have the entire amount paid off when the loan ends. With a home equity line of credit, you can make interest-only payments for a specified period. After that, you must either pay off the balance of the loan in a lump sum or refinance the amount you owe into a home equity loan.
