Chicagoland suburban prices were up 9.3% year over year during March, continuing a steady climb — with no signs of slowing, according to the Mainstreet Organization of REALTORS®.

Detached home prices in the suburbs rose to a median of $370,000 last month, while the number of homes sold fell. With 2,118 detached homes sales, the period marked a 13.8% year-over-year decrease. Meanwhile, average time on the market shrank from 63 days to 49.

The suburbs which saw increases in detached home prices in March were, in order: Maywood (up 81.2%), La Grange (40.4%), Lisle (38.1%), %); Downers Grove (31.6%), St. Charles (27.4%), Wheaton (26.0%), Arlington Heights (21.4%), Park Ridge (19.1%), Schaumburg (18.7%), Westmont (18.5%), Tinley Park (17.8%), Palatine (16.7%), Burbank (15.5%), Aurora (15.2%), Chicago Heights (14.3%), Glen Ellyn (11.3%), Park City/Waukegan (10.7%), Streamwood (10.6%), Antioch (10.5%), Hoffman Estates (10.2%) and Des Plaines (8.2%).

Overall, attached home prices rose even more starkly, though, increasing 15.3% during May to hit a median $260,000. Attached homes sales were also down with 1,172 homes sold, a 7.3% decrease, with average time on the market dropping from 41 days to 31.

In a press release, Mainstreet CEO John Gormley attributed the numbers to small inventory. “The little inventory that’s out there is moving quickly because there are still buyers looking to make a move,” Gormley said.

Mainstreet President Tim Ryan also offered his perspective. “People are getting used to the idea that rates are going to be stagnant, and yes, they might slowly decrease over time, but potential buyers are thinking, ‘The longer I wait, the more expensive the house is going to get,’” Ryan said.
