See how your home’s value was estimated by the Assessor’s Office.
This new Home Value Report shows the real estate sales and data that affected your home’s value when it was reassessed.
During a reassessment, the Assessor's Office estimates the value of your home. This estimated value depends on:
- your home’s characteristics (like building square footage) and location (like school district and neighborhood), and
- sales of similar homes.
To estimate this value, Assessor's Office data scientists train a computer program, called a statistical model, to follow the real estate market. This statistical model uses vast amounts of data about hundreds of thousands of sales to learn market trends. Then the statistical model uses these trends to calculate your home's value.
Your Home Value Report includes the top five most significant sales, along with all the data about your home that the model uses to estimate its value.
A Report is available if your home is a single-family home or small multifamily apartment building with six units or fewer.
To see your Home Value Report:
- First, enter your home's Property Index Number (PIN). If you don’t know your home’s PIN, you can find it using our Address Search or Cook Viewer.
- Then, select your PIN's Reassessment Year. If your home is in the south and west suburbs, choose 2026. If it is in the northern suburbs, choose 2025. If it is in Chicago, choose 2024.
- Respond to the CAPTCHA, and then click the Search button.
Disclaimer: This tool explains the model's estimates and is for educational purposes only. The estimated value and characteristics in this report may not be identical to what you receive on your Notice of Reassessment. This is because after the model produces its estimate of value, human residential analysts at the Assessor’s Office thoroughly review the model values, neighborhood by neighborhood, and may make changes to the property’s estimated value and characteristics. The Assessor’s Office built this tool to answer the question, “How did the model estimate my home’s value at the time of modeling?” It is not the Assessor’s “comps” tool for reviewing residential appeal filings.
