They are tax deductible as long as you itemize. Keep in mind that people only itemize when it exceeds their standard deduction. Now the only people that I've noticed that don't benefit from itemizing are mainly seniors who have a higher standard deduction and have a low amount of interest cause they're almost paid off and their property taxes are also very low.
Always consult your CPA or tax preparer for tax advice.
