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,
and
- is located either in the northern suburbs (choose Reassessment Year 2025) or Chicago (choose Reassessment Year 2024).
To start, find the 14-digit PIN for your home. If you don’t know your home’s PIN, you can find it using our Address Search or Cook Viewer. Then, enter your home’s PIN and select its Reassessment Year below to see your Home Value Report.
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.
