A home equity line of credit is a form of credit which allows you to borrow and use your home as collateral. Since for many, a home is their greatest asset, they tend to use these sorts of credit lines for large things like a college education for their children, medical expenses or for large unexpected bills as opposed to luxuries or day to day expenses. After receiving a home equity line, one is approved for an amount of credit, or a maximum that may be borrowed at any given time for the duration of the plan. On many occasions a lender will set a credit limit on a home equity loan by setting a percentage, after considering the amount of the appraised value of the home and the amount owed on the home. After the line of credit is approved, you will be able to borrow up to the set limit, usually in the form of checks. In some instances a borrower may be given credit cards to utilize, sometimes with minimum spending requirements.
