Sales History Reports

Property assessments are determined based on sale's ratio studies that include the previous three year's sales. Only properties considered as 'arm's length' are used in this process. 'Arm's length' is defined as "A sale between two parties, neither is related to or under abnormal pressure from the other." These sales reports contains all sales; however the arm's length sales that are used to determine assessed values are marked as "Y" in the column titled "Included in the Sales Study?"

The reports are sorted by year, then by class (Residential, Commercial/Industrial, & Farm).


If you need additional information regarding the property characteristics, please contact your Township Assessor.
