You need to be vigilant in order to be able to pay a lower property tax. Whenever your property is reassessed, make sure that the private contractor who does that takes down the right description and details. He may miss out on minor details or exaggerate the unwanted ones. In both the cases, you would bear the loss. Therefore, be on a look out when he comes for reassessment because it is the assessed value of your property that is the main calculative factor in your property tax. There have been many cases where people have paid real big property taxes owing to wrong reassessment.
