Assessor
  
An assessor works for your local government with a purpose of figuring out how much your home, your land, and any improvements that have taken place on that land are worth. It’s done for tax purposes.
Lots of things are taken into consideration...from what your home is built out of, to where it’s located, to how big it is. This assessment is done every so often, based on state requirements. For example, in Illinois, everyone gets assessed every four years. Given that most real estate taxes are roughly 1.3% of the market value of the home, the higher the assessed market value, the higher the assessed taxes.
