If you bought a house in 2003, you may deserve a bigger real estate tax deduction than you think you do. If the seller paid real estate taxes in advance for a period during which you actually owned the home, include that amount in your deduction -- even if you didn't reimburse the seller.
As far as the tax law is concerned you paid tax, whether you did it directly or through a higher price for the house. Check your settlement sheet to make sure you don't overlook a money saver.
