FYI I am a tax pro and property manager, not an agent

William,
Don't count on it or the previous answers. Real estate agents are not qualified to give tax advice. I'd recommend you speak with a tax professional. Everything is "deductible" until you learn otherwise in an audit.

Absolutely. Interest on mortgages (first & second) as well as property taxes are tax deductable.

Good afternoon William:

Interest and property taxes are deductable on a second home. Another home that is an investment home has another whole set of tax and operational issues.

Rob

YES, and you can depreciate it if it is a rental. You need to have fire insurance.
