The “Best Week to Buy” Starts Sunday. Here’s What It Looks Like in Bartlett and Schaumburg.

Realtor.com has circled a week on the calendar: Sunday, September 27 through Saturday, October 3. According to its annual study, that’s the best week of 2026 to buy a home, both nationally and in the Chicago metro specifically. The kids are back in school, the summer buyers have either closed or given up, and the sellers who are still listed are starting to think about Thanksgiving.

It’s a fun headline. But a metro-wide score built on eight years of seasonal patterns doesn’t tell you much about a three-bedroom ranch in Streamwood. So let’s look at what the study actually measures, and then at what’s actually for sale in our corner of the northwest suburbs this morning.

How Realtor.com picked the week

The study scores every week of the year on six seasonal measures: how many homes are for sale, how many new listings come on, listing prices, how long homes sit, how many buyers are shopping, and how often sellers cut their price. It uses data from 2018 through 2025, skipping 2020 for obvious reasons. Mortgage rates are deliberately left out because they don’t follow the seasons.

For the Chicago metro, the typical “best week” has looked like this:

• About 16.8% more homes for sale than an average week
• Roughly a third less buyer competition than the busiest week of the year
• Listing prices about 5.8% below the year’s peak
• Homes sitting about 10 days longer than during the fastest week

Worth saying plainly: that’s the historical average, not a forecast for 2026. Realtor.com’s own economist calls it a window, not a deadline. Early fall usually means more choice, and late fall usually means more room to negotiate.

The Chicago twist

Chicago isn’t following the national script this year. In Realtor.com’s August report, homes for sale in the Chicago metro were down about 6% from a year earlier, while the national count was up. New listings fell 7.5%, the second-steepest drop among the 50 largest metros. The median listing price here was around $395,000, up about 5% on the year. Redfin reported that more than 43% of Cook County homes sold above asking in August.

So the “best week” in Chicagoland isn’t a clearance sale. It’s the week the line gets shorter, not the week the prices collapse.

What’s actually on the market out here

Metro numbers blend the Gold Coast, Naperville and Joliet into one figure. To get closer to home, I checked this morning’s active single-family and townhome listings across seven towns we work in every day: Bartlett, Carol Stream, Elgin, Schaumburg, Bloomingdale, Streamwood and Hanover Park. Here’s what came back:

• 616 active listings across the seven towns: 184 in Elgin, 153 in Schaumburg, 77 in Bartlett, 57 in Streamwood, 54 in Carol Stream, 50 in Bloomingdale and 41 in Hanover Park.
• 174 of them, about 28%, are priced below where they started. In Elgin and Schaumburg the share is closer to three in ten.
• Of the listings with a clear list date, roughly four in ten have been on the market 30 days or more.

That 28% is not the same measure as Realtor.com’s metro “price cut” share, which counts reductions in a given month. Ours counts any cut since the home was listed. Still, the local story matches what the seasonal data predicts. The shiny new listings still move fast. But there’s a growing group of homes that went on the market in August, didn’t sell, and now belong to sellers who are more willing to talk.

If you’re buying this fall

The opportunity isn’t in the brand-new listing that went up Thursday with professional photos and a sharp price. That one might still get several offers. The opportunity is in the second tier:

• Homes that have sat 30+ days. Every week on the market costs the seller another mortgage payment, tax proration and lawn service. After a month, most sellers start thinking about net proceeds instead of the number they hoped for.
• Homes that already cut their price once. One cut often means the seller has accepted reality and may go further for a clean offer.
• Back-on-market homes. When a deal falls through in October, the seller now has a real deadline, and usually a clearer idea of what the inspection turned up.

Practical steps: get your pre-approval letter updated before Sunday, set your search alerts for price changes and not just new listings, and ask for the full listing history on anything you like. A home that’s been listed, pulled and relisted can look brand new on the apps. The MLS shows the whole history.

On financing, just one line: rates are higher than they were a year ago, and a fall price discount can offset a real chunk of that on the monthly payment. Run the numbers on the actual house rather than the headline.

If you’re selling

The fact that this is buyer-friendly week doesn’t make it a bad week to list. With new listings down sharply around the metro, a well-prepared home in Bartlett or Bloomingdale faces fewer lookalikes than it would in April. The buyers still shopping in October are usually serious. They’re relocating, their lease is ending, or they already sold.

The catch is pricing. Base your list price on September’s closed sales, not on what the neighbor got in May. With more than a quarter of local listings already reduced, buyers are watching for the ones that started too high. You get one first impression on the MLS, and “price reduced” is not the badge you want on it.

And if your timeline is flexible, spring is still a legitimate plan. You’ll get more buyers and more competing sellers, and prices usually peak then. That’s a trade-off, and either choice can be right depending on your situation.

The bottom line

The “best week to buy” is really just the start of a season. For the next couple of months, patient buyers in the northwest suburbs will have more room to negotiate than at any point since last winter, especially on homes that have already been sitting. Sellers who price correctly from the start can still do very well, because there are fewer of them competing this year.

If you’d like a list of the homes in your target town that have cut their price or passed 30 days on market, or a September-based value check on your own place, just reach out. No pressure, and no sales pitch dressed up as a market report.
