Windham's Assessing needs are currently contracted with MRI. Each MRI employee will be wearing an identification badge and driving either an MRI and/or Town of Windham marked vehicle. Windham Police also have vehicle makes, model and registration numbers, as well as, the names and photos of each contractor. Do not hesitate to call Police 603-434-5577 or Assessing 603-434-7530, ext. 5006 with concerns.
Primarily two MRI staff members can be found sharing duties in the Assessing Department or conducting inspections around Town.
What is an Abatement? An abatement is an assessment appeal process that occurs when, generally, there must be either an error in the physical data of your property or the assessment must not be proportional to other properties.
