More Houses, Higher Prices: The Weird Summer Standoff in DuPage and Cook

Here’s a riddle for you: how can there be more homes for sale and higher prices at the same time? That’s not supposed to happen in the tidy version of economics they teach you in high school. But that’s exactly what’s playing out across Chicagoland this summer, and if you’ve been sitting on the fence about buying or selling around Bartlett, it’s worth understanding why.

The inventory dam is finally cracking

The number that caught my eye this week: available inventory in DuPage County jumped about 9% to 3,924 homes. That might sound like a dry statistic, but for anyone who’s been house-hunting in Carol Stream, Bloomingdale, or Glen Ellyn over the past couple of years, it’s genuinely a big deal. Nationally, inventory ticked up less than 1% over the same stretch. DuPage grew nine times faster than the country as a whole.

Why? In a word: confidence. As one market update put it, sellers who were out are coming back, driven by higher prices and faster timelines. Homeowners who’ve spent years locked into a 3% mortgage — the so-called golden handcuffs — are finally deciding the equity gain and the quick sale are worth making the move. More sellers listing means more choices for buyers. That’s the good news if you’re shopping in Bartlett or Streamwood right now.

But prices haven’t gotten the memo

You’d think a wave of new listings would cool prices off. Not yet. Statewide, Illinois home prices were up 5.6% year over year in May, with a median price of $333,814 and roughly 11,700 homes sold — sales themselves up 4% from a year ago. Chicago proper is running even hotter: up 6.3% over the last three months to a median around $420,000, with homes selling in 47 days versus 50 a year ago. Faster and pricier.

Drill into Cook County and the story gets even more interesting for those of us on the northwest side. Schaumburg sits at a $339,815 median (up a modest 1.7%), while Des Plaines climbed a striking 11.9% to $374,796. Oak Park led the pack with a jaw-dropping 15.1% jump. The takeaway: the added inventory is being absorbed almost as fast as it hits the market. Buyers are hungry, and they’re not letting extra listings turn into a fire sale.

The demand is real, not just talk

If you want proof that buyers are actually pulling the trigger and not just browsing listings at midnight, look north to Lake County, where pending sales rose about 13% year over year to 1,077 — the largest jump since early 2025 — and closed sales followed with a 4% increase to 976. Contracts are turning into keys-in-hand. That’s a healthy, functioning market, not a speculative bubble.

So what does this mean for you, right here in Bartlett?

Bartlett straddles Cook and DuPage counties, which means we’re getting a taste of both trends at once — more inventory and stubbornly firm prices. Here’s how I’d read it depending on where you stand:

• If you’re a buyer: This is the most breathing room you’ve had in a while. More listings across Carol Stream, Hanover Park, and Streamwood means less of the frantic, waive-every-contingency panic of the past couple springs. But don’t confuse “more choices” with “buyer’s market.” Homes are still selling in under 50 days. Get pre-approved, know your number, and be ready to move when the right one shows up.
• If you’re a seller: The window is genuinely good — prices are up, buyers are active, timelines are quick. But that 9% inventory bump is your competition. The days of listing anything and watching ten offers roll in are fading. Price it right, present it well, and it’ll move. Overprice it and you’ll sit while the neighbor’s well-staged home gets the offer.
• If you’re on the fence: The golden-handcuff crowd is starting to unlock. If you’ve been waiting for a sign that other sellers are moving so you’re not the only one out there, this is it.

The bottom line

What we’re seeing isn’t a market that’s overheating or crashing — it’s one that’s normalizing. More homes, steady demand, quick sales, and prices that keep grinding upward at a sustainable pace. For a Chicagoland summer, that’s about as balanced as it gets. The panic-buying era is easing, but the fundamentals underneath the northwest suburbs — good schools, commuter access, and genuine demand — haven’t budged.

If you’re trying to figure out what your Bartlett-area home is worth in this specific moment, or whether the extra inventory means it’s finally your turn to buy, that’s exactly the kind of question worth talking through with a real human who knows these streets.
