A Home Loans or home equity line of credit is a form of revolving credit in which your home serves as collateral. Because the home is likely to be a consumer's largest asset, many homeowners use their credit lines only for major items such as education, home improvements, or medical bills and not for day-to-day expenses. With a home loans, you will be approved for a specific amount of credit--your credit limit, the maximum amount you may borrow at any one time under the plan. Many lenders set the credit limit on a home equity line by taking a percentage (say, 75 percent) of the home's appraised value and subtracting from that the balance owed on the existing mortgage.

Lines of credit vs. traditional second mortgage loans
If you are thinking about a home equity line of credit, you might also want to consider a traditional second mortgage loan. A second mortgage provides you with a fixed amount of money repayable over a fixed period. In most cases the payment schedule calls for equal payments that will pay off the entire loan within the loan period. You might consider a second mortgage instead of a home equity line if, for example, you need a set amount for a specific purpose, such as an addition to your home.
