Property Assessments can be done by request. Unfortunately if you/ve purchased a new home in Easton, they will not assess the home for three years from closing date. If you are preparing to sell your home, you may be better off to leave the assessment at the higher number to help confirm value.
Most towns in mass have seen a decrease. Towns are also seeing an increase in taxes. When the time of the year for abatement comes, it doesn't hurt to try to have yhe value of your home lowered. It could go higher too, but it is unlikely. You generally want it higher when you are selling. People look at the zestimate, and the assessed value and have that figure in their head when viewing properties.
