If you are talking about the Tax Appraised Value, that has nothing to do with market value in my opinion. Some homes may sell well below the tax value and some may sell well above. Tax values can also change dramatically from year to year. Remember the person or perhaps the machine setting this value has likely never seen the house and most likely has never been inside. So that's a tall order for them to set any kind of market value for the house. Listen to your realtor and study the reports they give you and also get an idea from the other houses they've shown you. Most consumers tend to know a bargain when they see one in my experience.
