The Housing Market Tracker is a new, first-of-its-kind map from the Assessor's Office that shows real estate market trends and individual sales in Chicago's community areas and Cook County municipalities.
The Assessor's Office has a statutory duty to estimate the Fair Market Value of property in Cook County. For residential property, our office primarily does this by following real estate sales trends. Buyers and sellers set prices for homes, and the CCAO aggregates these market trends for use in its valuation models.
In the past, the CCAO has shared information about sale prices through its valuation reports and data portal. For the first time, however, the dashboard below collects and displays this data by community area within Chicago and municipality in the rest of Cook County.
The dashboard illustrates sale trends from 2020 to 2024 for different residential property types (single-family, condo, and multi-family) by geography. Users can dive deeper and explore individual sales as well, with the option to filter by price and property characteristics.
To see which home sales were most significant in estimating a single- or multi-family home's Assessed Value, users can explore CCAO's Home Value Report.
