Illinois Real Estate Market Analysis
Illinois's real estate market spans a wide range of economic conditions, demographics, and price points. Whether you're a first-time buyer looking for the most affordable Illinois metros or an investor weighing relative market strength, the PropertyIQ Score gives you a single data-first read — built from Zillow price momentum and Realtor.com market-flow signals, updated monthly — of how each market compares to its state.
Illinois housing offers the Midwest's sharpest value proposition, with Chicago metro prices well below comparable coastal cities despite access to world-class amenities, corporate headquarters (Boeing, Caterpillar, Deere), and cultural infrastructure. Property tax rates are the state's most significant investor risk factor — an important consideration when reading how individual Illinois markets are positioned relative to the state.

Frequently Asked Questions
How many housing markets does PropertyIQ track in Illinois?
PropertyIQ currently tracks 28 metro areas and 102 counties in Illinois, each with its own PropertyIQ Score, home value trend, and days on market reading, refreshed monthly.
What does a PropertyIQ Score of 50 mean for a Illinois market?
A score of 50 marks Illinois's own state average demand momentum. PropertyIQ computes scores nationally across every US market, then calibrates the scale so a Illinois market is read against Illinois's own typical momentum rather than the national average. A market scoring above 50 is positioned to outperform the Illinois average over the next three years, while one below 50 is positioned to lag it.
Where can I find ZIP code level housing data for Illinois?
Every metro area and county listed on this page links through to its own ZIP codes, and each ZIP has its own market page with home value, rent, and days on market data. Start from a Illinois metro or county below, then drill into ZIP codes for the most localized data available.
What data sources does PropertyIQ use for Illinois market data, and how often is it updated?
PropertyIQ ingests fresh data every month from Zillow home values, Realtor.com days on market and price cut activity, Redfin, the US Census Bureau, FRED, the Bureau of Labor Statistics, and the Bureau of Economic Analysis. Every metro, county, and ZIP page for Illinois shows a last updated date, and PropertyIQ Scores are recomputed monthly once that new source data lands.
