Homeowners in Evanston Township were mailed Reassessment Notices on August 8, 2022, and have until September 9, 2022, to file an appeal. The estimated Fair Market Value listed on the Reassessment Notice will be reflected on tax bills in 2023.
Residential assessments are based on recent sale prices of similar properties. In 2021, the median sale price for single-family homes was $620,000; the median sale price for condos was $245,000, and $510,000 for small apartment buildings.
The Assessor’s estimated median market value for single-family homes in 2022 is $540,000, the median market value for condos is $252,000, and $510,000 for small apartment buildings.
The Assessor's Office hosts virtual and in-person events to provide information and answer your questions about reassessments and appeals. Visit our events page here.
The data below shows the Assessor's median estimated market values of all homes throughout Evanston Township, and sales trends from 2017-2021.
Compare the Real Estate Market to the Assessor's Estimate of your Home
Every assessment township is divided further into Neighborhood Codes. You can find your home’s neighborhood code on its Reassessment Notice and on the PIN detail page. Homeowners can compare the real estate market to the Assessor's estimate of their home’s value using the interactive map below.

Assessment Appeals
Property owners have the right to file an appeal. Appeals can be filed online and are completely free, a lawyer is not required. If the property characteristics listed on your assessment notice are incorrect, or if the estimated market value of your home is significantly more than what you believe your home could sell for in the current real estate market, you should consider filing an appeal. A good rule of thumb is this: If the property characteristics on this notice are correct and the estimated market value is within 10 percent of what you think your home is worth then it is unlikely that an appeal would change your property’s assessed value enough to significantly affect its property tax bill.
The deadline to file an appeal for properties in Evanston Township is September 9, 2022.
3 Reasons for filing an Assessment Appeal
1. Lack of Uniformity - Either you or our analysts can look at comparable properties (properties similar to yours) and determine whether the assessed value of your property is in line with the assessed values of other comparable properties.
2. Overvaluation - Supporting documentation, such as recent closing statements, or information about purchase prices of homes similar to yours can be submitted.
3. Incorrect Property Description - If a reassessment notice lists an error such as incorrect square footage, classification, or an error that may affect market value, an appeal can be filed. Supporting documentation such as property record cards or dated photos may be submitted with your appeal. It is important to remember, however, that a minor error does not necessarily indicate an incorrect assessment.
Market Value vs. Assessed Value
After estimating the market value of a home, the Assessor’s Office calculates the home’s Assessed Value based on its Level of Assessment.
Levels of Assessment are set by Cook County Ordinance based on the property’s major class. Single-family homes, condos, and all other 200-class properties have a 10% Level of Assessment, so the property’s Assessed Value equals 10% of its estimated market value.
A home valued at $500,000 has an assessed value of $50,000.
Note that it is not the Assessed Value that is taxed. The taxable value of the home is its final Equalized Assessed Value. This requires two more numbers:
-
The Equalizer (also called the Multiplier), is calculated every year by the Illinois Department of Revenue. All properties in Cook County have the same Equalizer. Equalized Assessed Value, or EAV = the Equalizer x Assessed Value. Example: with an Equalizer of 3.0, this home’s EAV = 3.0 x $50,000 = $150,000.
-
Any homestead exemptions, like the Homeowner or Senior Exemptions, are subtracted from the home’s EAV and are the same throughout Cook County. For example, the Homeowner Exemption subtracts $10,000 from the EAV, and the Senior Exemption subtracts $8,000 from the EAV. Example: with the Homeowner and Senior exemption, the home’s final EAV after exemptions = $150,000 - $10,000 - $8,000 = $132,000. This is the number to which the tax rate is applied to calculate a second installment property tax bill.
How does the model know what my home is worth?
“The model” is a computerized statistical model that uses real estate market data to estimate the value of homes that haven’t sold. These models are often called Automated Valuation Models and are the standard for conducting a computer-assisted mass appraisal.
The goal of the model is to answer this question: “What would the sale price of every home be if it had sold recently in an arms-length transaction?”
To answer this question, we use a two-step process:
-
Modeling. First, we use computer code to analyze data about home sales. Any two homes may have different characteristics (location, number of bedrooms, etc.) and sale prices. But there are consistent patterns in how characteristics affect sale prices on average. It’s important to detect these patterns accurately. To do that, we use computer code to train a predictive machine learning model, which learns to recognize complex patterns much faster than a human could. The output of this step is a model which can be used to predict any home’s sale price based on its characteristics and these learned patterns.
-
Valuation. We then use the model created in Step 1 to predict values for all residential properties. These predicted values are the scope of this report, but these values are subject to change. Estimated values produced by the model are reviewed by software and by our expert analysts, who review assessed value changes by neighborhood and property class and make adjustments as necessary.
Finally, we mail Reassessment Notices to homeowners with their property’s estimated market value, its characteristics, and its assessed value.

Sales Ratio Study
In the 2022 reassessment of Evanston Township, the Assessor's Office met 3 out of 3 IAAO standards for high-quality assessments in a sales ratio study. Sales ratios are the ratio between a property’s estimated value and its recent sale price. A sales ratio study is a way to self-assess and ensure that the Assessor's Office is accurately valuing properties. The IAAO is an international agency that sets assessment industry standards and best practices. Below are the results of our sales ratio study, which measures three metrics based on sales ratios.
