A home equity line 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 equity line, you will be approved for a specific amount of credit-your credit limit-meaning the maximum amount you can borrow at any one time while you have the plan.
Many lenders set the credit limit on a home equity line by taking a percentage (say, 75 percent) of the appraised value of the home and subtracting the balance owed on the existing mortgage. For example:
| Appraisal of home | $100,000 |
| Percentage | x75% |
| Percentage of appraised value | $75,000 |
| Less mortgage debt | -$40,000 |
| Potential credit line | $35,000 |
