Buying a home in Illinois can look very different depending on where you are searching. In some cities, homes stay on the market for weeks. In others, buyers may have to move quickly because there are fewer homes available and properties can receive offers soon after they are listed.
Housing market data compiled by Redfin shows which Illinois cities had some of the strongest competition among homebuyers during January through October 2025. The rankings considered factors such as how long homes stayed on the market, how close the final selling price was to the asking price, and how many homes were available for sale.
What Makes a Housing Market Competitive?
A competitive housing market usually means there are many buyers looking for homes compared with the number of properties available.
When this happens, buyers may have less time to make a decision. Sellers may receive multiple offers, and some homes can sell for more than their original asking price.
Redfin’s ranking looked at three main factors: months of housing supply, the average sale-to-list price ratio, and the median number of days homes spent on the market.
Wheaton Had One of the Strongest Markets
Wheaton ranked at the top of the Illinois list. Homes there spent about 43 days on the market on average, and the average sale-to-list ratio was 102.2%. That means homes were generally selling for slightly more than their asking prices.
About 60% of homes sold above their list price, while 62% went off the market within two weeks.
Chicago Suburbs Saw Strong Buyer Competition
Many of the communities on the list are located in the Chicago metropolitan area. Mount Prospect, Oak Park, Evanston, Arlington Heights, Downers Grove, Des Plaines, Skokie, Hoffman Estates, Schaumburg and Palatine were among the communities included.
Naperville, Joliet, Tinley Park and Waukegan also appeared on the list. In several of these communities, roughly half of the homes sold for more than their asking price.
Rockford Homes Moved Quickly
Rockford stood out because homes spent much less time on the market than in many of the Chicago-area communities.
The average was about 12 days on the market, with only 1.24 months of housing supply. About 63.5% of homes went off the market within two weeks.
Those numbers show how quickly buyers were purchasing available homes in the Rockford area during the period studied.
Springfield Was Also a Competitive Market
Springfield ranked among Illinois’ competitive housing markets as well.
Homes spent about 13 days on the market, and the city had approximately 1.21 months of housing supply. Nearly 64% of homes went off the market within two weeks.
Unlike some Chicago suburbs, however, Springfield’s average sale-to-list ratio was 99.7%, meaning homes generally sold very close to, but slightly below, their asking prices.
Other Illinois Cities Made the List
Competition wasn’t limited to the Chicago area.
Peoria and Champaign were also included among the state’s competitive markets. Peoria homes spent about 21 days on the market, while Champaign homes averaged about 45 days.
Aurora was another major Illinois city on the list, with nearly 49% of homes selling above their asking price during the period studied.
What This Means for Illinois Homebuyers
People shopping in a competitive market should be prepared before they find a home they like.
That can mean knowing their budget, getting financing organized, and researching the property before making an offer. Buyers should also remember that competition can change from one neighborhood to another, even within the same city.
A market that was highly competitive in 2025 may also look different today, so buyers should consider current local conditions before making a decision.
What This Means for Illinois Homeowners
For homeowners, strong buyer competition can be encouraging when it is time to sell.
Homes in areas with limited inventory may attract buyers quickly, particularly when the property is priced appropriately and is in good condition. However, homeowners should not assume that every property will sell above its asking price simply because the surrounding market is competitive.
Location, property condition, price, neighborhood demand, and the number of similar homes available can all affect the final sale.
Illinois Housing Markets Can Vary Widely
The housing market is not the same throughout Illinois.
Some communities had homes selling within a couple of weeks, while others had properties staying on the market considerably longer. Some areas regularly saw homes sell above asking price, while others stayed closer to the original list price.
For buyers, sellers, and property owners, understanding these local differences can provide a clearer picture of what is happening in their part of Illinois.
