Yes it is. I don't get a 1098 from my bank on the TT so I call them every year to make sure our numbers match. Keep that in mind also.
From the IRS publications:
For you to take a home mortgage interest de- duction, your debt must be secured by a quali- fied home. This means your main home or your second home. A home includes a house, con- dominium, cooperative, mobile home, house trailer, boat, or
The interest you pay on a mortgage on a home other than your main or second home may be deductible if the proceeds of the loan were used for business, investment, or other deductible purposes. Otherwise, it is consid- ered personal interest and is not deductible.
Hope it helps.
