Housing market indicators

All of these property level data sets are connected to parcel-level data files from the county Assessors offices that include data on every parcel in the Chicago metropolitan area. All of these parcel-level data sets include historical data and are updated on a regular basis ranging from every week to every year depending on the data set.

Property Sales Activity

This indicator provides information on how active local residential property markets are, what types of properties are being purchased, who is buying them, and how much buyers are paying for properties.

Share of Sales, Business Buyers

This represents a range of investor types from small mom-and-pop investors to large Wall Street-traded equity funds. Heightened levels of single family homes purchased by business buyers is often indicative of a distressed and low priced inventory of homes, and low demand for owner-occupied housing in a neighborhood.

Cumulative Foreclosure Filings Activity

Annual levels of foreclosure filing activity likely do not convey the impact that foreclosure has had in a particular community, as geographies vary in density and size, and the drivers behind the Great Recession foreclosure crisis led to very different annual patterns of foreclosure filing activity across the region. This indicator represents the cumulative impact of foreclosure in a neighborhood measured as the unique share of residential properties that have had at least one foreclosure filing since 2005.

Foreclosure Auctions

These are properties that have completed the foreclosure process.

The level of completed foreclosure auctions activity in a neighborhood indicates distress in a local housing market.
