Three Months of Supply Isn’t Enough — What the Summer Squeeze Means for Bartlett Buyers

Here’s the number that tells the whole story right now: three months of supply. That’s what Illinois is sitting on statewide as of the latest Redfin read, and it’s actually down year over year even though the raw count of homes for sale ticked up to about 46,000. Read that twice. More homes listed, less breathing room. That’s not a contradiction — it’s what happens when the stuff that hits the market gets snapped up nearly as fast as it appears.

For anyone house-hunting in Bartlett, Carol Stream, or Streamwood this August, that three-month figure is the real headline. A “balanced” market is generally considered five to six months of supply. We’re at half that. Which means if you’ve been circling a listing on Stearns Road waiting for a price cut that feels overdue, the market may not agree with you.

Chicago’s Price Tag Keeps Climbing

The city proper just clocked an average home price of around $430,000 — up 11.7% from a year ago, per Redfin, with a competitiveness score of 66 out of 100. Double-digit appreciation in a year when everyone keeps insisting rates are “crushing” the market. Both things are true at once, and that’s the part people struggle with.

The suburbs don’t move in lockstep with the city, but they rhyme. When Chicago proper gets expensive and inventory stays thin, the pressure rolls outward — to Elgin, to Schaumburg, to Bloomingdale and Hanover Park, where a buyer priced out of a $430K city average can still find a two-story with a yard and a two-car garage. That outward pressure is exactly why our little corner of DuPage and Kane counties hasn’t seen the cooldown the doom-scrollers keep promising.

Gardner Says Sellers Are Back in Control

Economist Matthew Gardner dropped his Q2 2026 housing update this month, and his framing was blunt: sellers are back in control. His reasoning is the one we keep coming back to — the “structural high rate headwinds” aren’t a passing storm, they’re the climate now, likely persisting through the back half of 2026.

Here’s the mechanism, because it matters. Millions of homeowners locked in mortgages at 3% or less during the cheap-money years. Trading up to a new house today means trading that golden rate for something far higher. So they don’t move. That “lock-in effect” is the quiet hand keeping inventory strangled — and it’s why you can have more listings on paper and less actual choice on the ground. The people who are selling know the buyer pool is deeper than the listing pool.

So What Do You Actually Do About It?

If you’re a buyer: stop waiting for a crash that the fundamentals aren’t supporting. That doesn’t mean overpay — it means come correct. Get fully pre-approved, not pre-qualified. Know your true monthly number at today’s rates. And be ready to move on a good Bartlett or Carol Stream listing within days, not weeks, because in a three-month-supply market, the well-priced ones don’t linger.

• Widen the net. If the Bartlett schools you want come with a bidding war, Streamwood and Hanover Park often deliver similar commutes for real money less.
• Watch days-on-market, not just list price. A home that’s sat three weeks in this market has a story — go find out what it is. That’s your negotiating leverage.
• Rate-and-date the mortgage. You marry the house, you date the rate. If it drops, you refinance. Waiting on the sidelines just means paying more for the same house later.

If you’re a seller: Gardner’s right that you’ve got the upper hand, but “in control” isn’t a license to fantasy-price. Buyers are qualified and motivated, but they’re not stupid — they’ve watched rates too. Price it sharp, stage it clean, and the compressed supply does the rest of the work for you.

The Bottom Line for Chicagoland

The national story is “high rates, frozen market.” The local story is more interesting: thin inventory, resilient prices, and outward pressure from a pricey city keeping the western suburbs surprisingly firm. Three months of supply isn’t a buyer’s market and it isn’t a bubble — it’s a market that rewards the prepared and punishes the paralyzed.
