If you decide to apply for a home equity line of credit, look for the plan that best meets your particular needs. Read the credit agreement carefully, and examine the terms and conditions of various plans, including the annual percentage rate (APR) and the costs of establishing the plan. The APR for a home equity line is based on the interest rate alone and will not reflect the closing costs and other fees and charges, so you?ll need to compare these costs, as well as the APRs, among lenders.

Interest rate charges and related plan features
Home equity lines of credit typically involve variable rather than fixed interest rates. The variable rate must be based on a publicly available index (such as the prime rate published in some major daily newspapers or a U.S. Treasury bill rate); the interest rate for borrowing under the home equity line changes, mirroring fluctuations in the value of the index. Most lenders cite the interest rate you will pay as the value of the index at a particular time plus a “margin,” such as 2 percentage points. Because the cost of borrowing is tied directly to the value of the index, it is important to find out which index is used, how often the value of the index changes, and how high it has risen in the past as well as the amount of the margin.

Lenders sometimes offer a temporarily discounted interest rate for home equity lines–a rate that is unusually low and may last for only an introductory period, such as 6 months.

Variable-rate plans secured by a dwelling must, by law, have a ceiling (or cap) on how much your interest rate may increase over the life of the plan. Some variable-rate plans limit how much your payment may increase and how low your interest rate may fall if interest rates drop.

Some lenders allow you to convert from a variable interest rate to a fixed rate during the life of the plan, or to convert all or a portion of your line to a fixed-term installment loan.

Plans generally permit the lender to freeze or reduce your credit line under certain circumstances. For example, some variable-rate plans may not allow you to draw additional funds during a period in which the interest rate reaches the cap.
