Township Appeal Results Overview (Leyden Township)

These results show how often appeals changed outcomes in Leyden Township. They also show how assessed values changed from proposed to final. In Cook County, property owners can file appeals when they believe an assessment is not fair, using evidence like comparable sales, property details, or income information (for some property types).

At Cook County Tax Appeals, we track township trends. This helps property owners see what happens after appeals are filed. It goes beyond what the process says “should” happen.

Overall Appeal Success Rate (Leyden Township)

In Leyden Township, 2,761 out of 11,013 appeals were successful, for an overall success rate of 25.1%.

A “successful” appeal here means the outcome is marked “Change.” In plain terms, that means something was adjusted after review (often assessed value, and sometimes classification or exemptions depending on the filing).

Even when the process feels confusing, the results show that changes do happen. That is why it helps to review your notice carefully and compare your property to similar ones in your area.

Appeal Success Rate by Property Class (Leyden Township)

Cook County groups properties into class codes to describe property types (for example, many homes fall under Class 2 variations like 2-03).

Here is how to think about the bigger buckets:

• Class 2 (2-xx): Residential homes and many common homeowner categories

• Class 3 (3-xx): Apartment buildings with 7 or more units

• Class 5 (5-xx): Commercial and industrial property types

What the chart shows: success rates can look very different by class. In Leyden Township, several Class 5 and Class 3 categories showed higher “Change” rates than many of the larger residential Class 2 groups (see the chart).

Cook County Tax Appeals regularly analyzes these class-by-class trends across Cook County townships, because property class often affects what evidence works best and what review standards are used.

Assessed Value Changes Explained (Leyden Township)

Across all appeals in this dataset:

• Average proposed AV: $109,212

• Average final AV: $102,367

• Average reduction: -$6,846 (about -6.3%)

Why this matters: assessed value is a key input in how property taxes are calculated, and a lower assessment can reduce a property’s share of the overall tax burden in the area.

Cook County Tax Appeals helps owners understand what their assessed value means, what is driving changes, and when it may be worth challenging.
