The reasons the Assessor gave

Every decision carries a stated reason. These are the ones that appear most often on New Trier decisions, and how often each was attached to a reduction rather than a refusal.

Reason given	Decisions	Reduced
This is a result of a market analysis of your property as well as an analysis of comparable properties.	18,337	25.4%
This is due to an analysis of the actual sale transaction of the property.	1,218	0.0%
This is due to your property's uniformity with comparable properties.	461	0.0%
This result is based upon consideration of the appraisal submitted and an analysis of recent comparable property sales.	330	0.0%
This is due to income, market or cost analysis supporting the assessment.	271	0.0%

A reason seen fewer than 30 times shows no rate, for the same reason a township with a handful of appeals shows none.
