The spring market is off to a competitive start across Chicagoland suburbs, with rising sales, higher prices and little relief on inventory, according to Mainstreet REALTORS®’ March data report. 

Detached home sales increased 7.5% year over year during the month, reaching 2,134 closings compared to 1,985 during the same time in 2025. Homes also moved slightly faster, averaging 53 days on market, down from 54 days a year ago. Median prices climbed nearly 5% to $403,250. 

The bigger issue remains in supply. Inventory across the Chicagoland PMSA was just 1.5 months, far below the five to six months typically considered balanced. In some communities, such as Bloomingdale, only eight homes are currently available. 

That lack of inventory is intensifying competition, the data suggests. 

“Inventory is still severely constrained, and so we are seeing extreme competition for quality listings,” said Kinga Korpacz, president of Mainstreet REALTORS®. “Buyers are waiving attorney review and inspections and coming in with significant earnest money.”  

There are some signs of increased activity on the listing side, where Kane County saw new listings rise 14.5% year over year in March. 

As for the attached market, sales dipped slightly, with 1,086 homes sold compared to 1,094 last year, and market time increased from 42 to 54 days. Prices continued to rise, with the median climbing 5.6% to $285,000. 

Mainstreet CEO John Gormley added, “Even though prices are on an upward path in the Chicagoland suburbs, the market feels predictable.” 

Some suburbs are seeing homes sell much faster than they did a year ago. Arlington Heights saw average market time drop from 70 days to just 25. Similar trends played out in Downers Grove (59 to 36 days), Geneva (35 to 25), Lombard (48 to 25), Streamwood (49 to 30), Tinley Park (107 to 37) and Wheaton (24 to 10). 

In terms of sales volume, Aurora led the region with 100 detached home sales in March, followed by Naperville and Arlington Heights.
