LOL, James I still wish this site had a 'like' button! Please understand that an appraisal is not the same as an assessment. Similar but different. Both are nothing more than an opinion of value and they are sometimes based on very different criteria. For example, did the county tax assessor do an internal inspection of your new home? James is correct, be thankful that your property taxes didn't go through the roof. The real estate market determines the value of your home, not the appraiser, not the tax assessor, and not even a realtor.
