CHICAGO, IL - Interra Realty, a Chicago-based commercial real estate investment services firm, today released its Q1 2026 Suburban Chicago Multifamily Sales report. Among other findings, the firm reported that total sales volume increased by 56.9% year over year.
Data was collected by Interra’s suburban multifamily investment team of Managing Partner Patrick Kennelly, Managing Partner Paul Waterloo, Director Nathan Zito and Associate Andrew Stassi. The report tracked all multifamily sales in Chicago’s suburbs between $1 million and $50 million during the 12-month period ending in March 2026.
“The Chicago suburban multifamily market kicked off 2026 with real momentum, driven by bigger individual transactions and a surge in collar county investment activity,” said Kennelly. “If that trajectory holds, suburban sales volume could surpass $1 billion by year’s end.”
Interra recorded 54 suburban multifamily sales in the tracked price range during first-quarter 2026, the same number as a year earlier. However, those transactions totaled $360.1 million in 2026 compared to $229.5 million in 2025, an increase of 56.9%. The average deal size grew to $6.6 million in first-quarter 2026 from $4.2 million last year.
Half of all property sales occurred in Cook County, followed by DuPage County with 33.6% and Kane County with 15.4%. DuPage and Kane significantly outpaced the average deal size of $6.6 million, with $9.3 million and $11.1 million, respectively.
Across all sales tracked by Interra, the average price per unit grew by 4.3% year over year, rising to $148,209 from $142,102. A total of 2,430 units traded across the suburban multifamily market during the first quarter, up 50.4% from the 1,615 units sold in the year-earlier period. The jump in unit volume despite unchanged deal velocity suggests investors are increasingly pursuing larger, more institutional-quality assets. Supporting that trend, Interra recorded 11 transactions between $10 million and $50 million in the first quarter of this year, nearly twice the six deals completed over the same period in 2025.
As a leader in middle-market multifamily brokerage across the Chicago market, Interra closed 52 suburban transactions in the past 12 months. These include the $7.9 million sale of a nine-building, 36-unit rental townhome portfolio in Batavia; the $2.34 million sale of an 18-unit property at 9822 Nottingham Ave. in Chicago Ridge; the $2.2 million sale of 329 and 333 W. Hawthorne Circle, a two-building, 12-unit portfolio in Mount Prospect; the $1.9 million sale of 7631 W. 63rd Place, an 18-unit property in Summit; and the $2.75 million sale of the 16-unit 1860-1900 Parkside Drive in Park Ridge.
