To the extent this home is a second home and not a third or more that you are claiming a mortgage deduction for and the aggregate amount of the loan does not exceed $1,000,000 on your primary home and this second home the interest is permitted to be taken as a schedule a deduction. You may also have a home equite loan up to $100,000 and take that interest to as a deduction.
Not sure I understand your answer.
