Can I deduct other expenses on a second home other than taxes paid?

[CherylW]

This, from IRS' Publication 936:

Qualified Home

For you to take a home mortgage interest deduction, your debt must be secured by a qualified home. This means your main home or your second home. A home includes a house, condominium, cooperative, mobile home, house trailer, boat, or similar property that has sleeping, cooking, and toilet facilities.
