A $50,000 high-LTV home equity line of credit is an open-ended loan, paid as revolving debt, that is backed by the portion of the home's value that the borrower owns outright. Interest paid on a home equity line of credit is usually tax deductible. The rates quoted on Bankrate are based on a $50,000 revolving, open-ended line of credit with a loan-to-value ratio in excess of 80 percent.
