When you take out a home equity line of credit, you pay for many of the same expenses as when you financed your original mortgage. These include items such as an application fee, title search, appraisal, attorneys' fees, and points (a percentage of the amount you borrow). These expenses can add substantially to the cost of your loan, especially if you ultimately borrow little from your credit line. You may want to negotiate with lenders to see if they will pay for some of these expenses.

In addition to upfront closing costs, some lenders require you to pay continuing fees throughout the life of the loan. These may include an annual membership or participation fee, which is due whether or not you use the account, and/or a transaction fee, which is charged each time you borrow money. These fees add to the overall cost of the loan.
