Yes, property taxes are also deductible. If you don't escrow your taxes, that amount won't be printed on your end of year mortgage interest paid statement. If that'* the case, call your local tax assessor and he/she can give you the number. Or, you can go to your local municipality'* website and look it up.
As far as whether or not you should itemize or not depends largely on when you bought your home and home much interest and taxes you paid. If you bought your house in November or December of 2007, then it'* likely that you're better off taking the standard deduction. I'm not sure what the standard deduction for 2007 is for "married filing jointly". Whatever that number is, if it'* less than what you paid in property taxes and mortgage interest, then you're better off itemizing.
