U.S. Housing Market Snapshot

Nationally, home prices rose 2% while pending sales fell about 1%. DuPage County diverged sharply on demand: local pending sales surged 16.6%, nearly 19 percentage points above the national trend. However, inventory diverged in the opposite direction from Cook County—DuPage’s active listings rose 11.4%, far exceeding the national increase of about 3%. The county’s above-list rate of 40.3% still dwarfed the national 24%, but the gap narrowed from a year ago.

“The U.S. housing market faced some hurdles in August, as inflation and an AI-fueled economy kept mortgage rates high and weighed heavily on homebuyers, sellers, and investors,” said Chen Zhao, Redfin’s head of economics research. “Until recently, affordability and activity had been slowly improving for months, helping the market recover. But now, economic uncertainty and rising prices are keeping more people on the sidelines and slowing the market further. For buyers who need to buy, now is a great time because there’s less competition and a bit more inventory—for sellers, pricing competitively is key to attract attention.”

DuPage County Prices Rose More Than Double the National Rate

The median sale price in DuPage County climbed 4.8% year over year to $448,499, while national prices rose just 2%. The median price per square foot increased 4.1% to $253, confirming broad-based appreciation rather than a compositional shift. DuPage County continued to command a premium over neighboring Cook County ($383,716), reflecting the suburb’s strong school districts and lower density.

Despite the price gains, signs of moderation appeared. The sale-to-list ratio slipped to exactly 100% from 100.3% a year ago, and 13.7% of active listings carried a price cut. The share of homes selling above asking fell 4.2 percentage points to 40.3%. Sellers still held an advantage, but buyers were no longer conceding as aggressively as they did a year ago.

Pending Sales Surged 17% as National Demand Slipped

Pending sales in DuPage County soared 16.6% year over year to 1,085, the strongest gain among the Illinois counties tracked here, while national pending sales fell 1.3%. Homes sold also rose 3.9% to 1,009, confirming that the demand surge was translating into closed transactions rather than stalling in the pipeline.

Yet the demand increase coincided with a substantial inventory expansion. Active listings rose 11.4% to 3,607, and months of supply climbed to 2.5 from 2.1 a year ago. The median home took 51 days to sell, four days longer than last August. Buyers and more sellers entered the market simultaneously—activity boomed, but so did the options available to each side.

New Listings Surged 14%, Building Inventory

New listings in DuPage County jumped 14.3% year over year to 1,101, far outpacing the national 4% increase. The influx of supply pushed active listings up 11.4% and months of supply to 2.5—still below the national figure of about 4, but meaningfully higher than a year ago. DuPage was the only Illinois county in this report where inventory expanded rather than contracted.

For sellers, the rising tide of new listings meant more competition from other sellers. For buyers, 11% more active listings meant more choices and slightly less urgency. The shift was gradual—DuPage remained firmly below balanced territory—but directionally, the market moved toward buyers more than any other county in this report.

Starter and Non-Luxury Tiers Saw the Strongest Price Gains

Redfin analysis of MLS data • Rolling three-month period (May-July 2026)

Starter and non-luxury homes each rose 6.1% year over year, outpacing the high tier (4.8%) and luxury (4.0%). However, the high tier remained the most competitive: 56.2% of homes sold above asking and sales volume grew 4.7%. Luxury homes saw days on market fall 8 days, but sales volume dipped 4.2%, suggesting that buyers at the top were selective.

Above-list activity declined across the starter, non-luxury, and bottom tiers—falling 4 to 21 percentage points—while the high tier still gained 1.7 points. Competition concentrated in the $500K–$650K range, while buyers in other brackets gained negotiating leverage as inventory expanded.

How Buyers and Sellers Can Navigate DuPage County’s Market

If you’re buying in DuPage County, the data offers slightly better news than a year ago. Inventory is up 11%, days on market have lengthened, and the share of homes selling above asking has dipped. Use the additional supply to compare options carefully, and don’t feel pressured to waive contingencies. That said, about 40% of homes still sold above list, so aggressive offers remain necessary for the most desirable properties.

If you’re selling, prices are still climbing and demand surged nearly 17%. Price accurately to attract the wave of new buyers. But be aware that you face more competition from other listings than a year ago: Inventory is up 11%, and overpricing risks extended days on market. The days of universal bidding wars are fading; correct pricing from day one is more important than ever.
