If you take out a home equity loan, your interest payments may qualify for a deduction in addition to your mortgage interest. To qualify, you must have obtained the loan after Oct 13, 1987 and it must also be secured by your home.
For tax purposes, only the balance of the loan that is the smaller of $100,000 or your equity in the home qualifies for the interest deduction. Your equity is equal to the amount you could sell the home for minus the amount you still owe on the mortgage.
Fees paid in connection with obtaining the loan (attorney fees, appraisal, survey, etc.) are
not
tax deductible.
