Evidence
a)Â Â Â Â Â Â Â Â The Property Tax Appeal Board generally considers appeals with
respect to the correct valuation of property for assessment purposes based upon
the following contentions:
1)Â Â Â Â Â Â Â Â the subject property is not accurately assessed when its
assessment is compared to the assessments of other, similar properties in its
neighborhood; and/or
2)Â Â Â Â Â Â Â Â the market value of the subject property is not accurately
reflected in its assessment.
b)Â Â Â Â Â Â Â Â Proof of unequal treatment in the assessment process should
consist of documentation of the assessments for the assessment year in question
of the subject property and it is recommended that not less than three
comparable properties be submitted. Documentation must be submitted showing the
similarity, proximity and lack of distinguishing characteristics of the
assessment comparables to the subject property.
c)Â Â Â Â Â Â Â Â Proof of the market value of the subject property may consist
of the following:
1)Â Â Â Â Â Â Â Â an appraisal of the subject property as of the assessment date
at issue;
2)Â Â Â Â Â Â Â Â a recent sale of the subject property;
3)Â Â Â Â Â Â Â Â documentation evidencing the cost of construction of the
subject property including the cost of the land and the value of any labor
provided by the owner if the date of construction is proximate to the
assessment date; or
4)Â Â Â Â Â Â Â Â documentation of not fewer than three recent sales of
suggested comparable properties together with documentation of the similarity,
proximity and lack of distinguishing characteristics of the sales comparables
to the subject property.
d)Â Â Â Â Â Â Â Â The Property Tax Appeal Board may consider appeals based upon
contentions of law. Such contentions of law must be concerned with the correct
assessment of the subject property. If contentions of law are raised, the party
shall submit a brief in support of his position.
