Many people assume that property assessment and tax go hand in hand.  They figure that if the value of their property goes up, so will their taxes.  While this scenario is possible, it is not necessarily the case.  Let’s say that the value of your estate after assessment went up by 10 percent.  If the rest of your neighborhood mostly ended up with a 15 percent increase, your tax will actually go down.  Another consideration in the equation is the assessment factor for the area.  If the level of assessment on property tax was only fractional in years past and goes up to 100 percent, even if the value of your home rose to 10 times the normal amount, there would likely be no tax increase. property tax assessment
