Fox Valley Real Estate: Week of September 7–11, 2026

The market’s underlying tightness held all week, but the texture kept shifting. Naperville and the Tri-Cities are still moving fast for anything priced right, yet Geneva’s top end keeps softening and Tri-Cities sellers are back to offering concessions after two years of buyers waiving everything. The bigger throughline is development: Yorkville’s data-center fight went from council votes to an actual lawsuit, Aurora layered on new restrictions of its own, and several towns advanced new residential product that will shape supply into 2027. Rates were volatile — Freddie Mac’s weekly average sat at 6.71%, while daily trackers eased into the low 6.4s by Thursday.

Aurora (including West Aurora and downtown)

In August, the City Council voted 7–4 to reject a full data-center moratorium but layered on new rules anyway — banning water-hungry evaporative cooling and requiring setbacks near homes, building on March’s sound-study requirements (per Shaw Local). Aurora now has some of the stricter data-center rules in the state. Citywide median list is around $415,000 at roughly 30 days on market; West Aurora is the number to watch, up a striking 16% year over year to a $374,500 median. Aurora is still the affordability entry point versus the Tri-Cities, but West Aurora’s appreciation says that gap is narrowing.

North Aurora

North Aurora Road fully reopened between Pennsbury and Frontenac — a real showing headache resolved. The village is separately dissolving the Route 31 TIF ahead of its August expiration and studying a road diet between Mooseheart and Airport roads. Silverthorne Homes opened presale pricing in mid-August on its 99-home Silverleaf development. The lingering issue: the rail bridge replacement runs into late 2027, so factor that into commute talk.

Batavia

The council approved Residences at River Pointe — a 72-unit affordable housing complex at 400 S. River St. on a long-vacant limestone quarry, backed by $1 million in TIF — plus River Street Plaza, a new downtown gathering space. Competitiveness is around 74/100, average value near $472,000 (+5.1% year over year), pending in roughly 10 days; median list sits near $524,000. Batavia remains the value play of the Tri-Cities for buyers who want Kane County schools without Geneva pricing.

Geneva

Median list is running around $547,000, down 8–9% year over year — the high end is genuinely cooling, not cratering. It’s still one of the tightest Tri-Cities markets: well-priced homes draw multiple offers, but wishful pricing now sits. IDOT’s multi-year reconstruction of East State Street (Route 38) is underway, worth flagging to anyone near that corridor. My message to sellers still anchored to 2024 numbers: the days of naming your number are over.

Sugar Grove

Worth clearing up: the Kaneland School District 302 lawsuit trying to dissolve The Grove’s roughly $109 million TIF was dismissed back in November 2025, judge siding with the village. Crown Community’s 760-acre community at I-88 and Route 47 is legally clear to build, with Area 1’s 214 single-family homes on Merrill Road delivering through 2026. Forward-looking: a Sept. 16 public hearing at the Sugar Grove Library on requiring special-use approval for future data centers — trustees tightening process even as this project moves forward.

Naperville

The council unanimously approved M/I Homes’ 11 high-end downtown row homes at Main and Benton, plus greenlit The Atlas (236 apartments), Northwoods (64 townhomes) and Residences at Naper & Plank — a lot of attached product headed for inventory. Resale stayed tight: median list in the $590,000–$650,000 range depending on source, average value near $636,000 (+4.4% year over year), around 70/100 competitive, roughly three offers, ~43 days on market. Move-up buyers finally have a sliver of room; entry-level still doesn’t.

Oswego

No single headline dominated, but the pipeline is real: The Drake Group’s Polo Crossing (120 single-family homes plus 200 townhomes near Secretariat Lane and Wolf’s Crossing Road) is advancing alongside a separate 125-home, 243-townhome, 288-apartment mixed-use proposal. Downtown, The Reserve at Hudson Crossing’s second six-story building (104 units) opened this spring with new tenants filling in. Kendall County’s fastest-growing town keeps adding both rooftops and downtown vibrancy.

Yorkville

The data-center fight escalated. Residents formed Preserve Our Yorkville & Community LLC, hired an attorney, and filed suit arguing the ~1,037-acre Project Cardinal (Pioneer) and 540-acre Project Steel (Prologis) campuses — both approved earlier this year — will damage property values in neighborhoods like Caledonia. Combined developer contributions run around $91 million, including roughly $68.25 million toward the school district. Separately, Project Cardinal’s land-purchase closing deadline was pushed to Dec. 31, 2027. New construction keeps moving regardless, with new-build inventory near a $418,000–$425,000 median. If you have listings on Yorkville’s north or east side, expect this lawsuit to come up in showings.

County and rate backdrop

Kane County’s home value is near $383,000 (+4% year over year), pending in roughly 6 days; weekly closings ran about 135 sales at a ~$399,000 median (per Kane County Reporter). Kendall County’s median sale is closer to $370,000 (+4.8% year over year), but days on market crept to around 67 from 56 a year ago — worth watching as The Grove and Polo Crossing land. Rates bounced around all week: Freddie Mac’s weekly average read 6.71% for the week ended Sept. 3, while daily trackers eased toward 6.375% by Thursday, and Fannie Mae is still forecasting a drift toward roughly 6.3% by year-end. My read: don’t wait on a rate cut to change the math much — and if rates do drop further, tight inventory means competition snaps back fast.

National watch

The nationwide homebuyer-commission settlement (Tuccori v. At World Properties) hit a real deadline this week, and it runs through our own federal court. More than $120 million sits in a Global Settlement Fund, with NAR contributing $52.25 million and Compass, eXp World Holdings, HomeServices of America, Hanna Holdings and Douglas Elliman opting in. Judge Lindsay Jenkins, Northern District of Illinois, set final approval for Nov. 2; class members have until Sept. 17 to object or exclude themselves and Oct. 27 to file a claim.

Supporters — largely NAR and the opted-in brokerages, all parties to the case with an obvious interest in closing it out — argue one nationwide settlement beats fifty separate fights and returns money to buyers who paid the commissions being challenged. Critics counter that a fund this size across a nationwide class works out to a modest per-claimant amount, that NAR settled without admitting wrongdoing, and that NAR’s own materials note no additional practice changes for members — reading the opt-in structure as buying peace rather than reform. I’d treat NAR’s framing here as advocacy, not a neutral account.

The bottom line

Nothing structural changed this week — inventory is still thin, rates are still bouncing around in the 6s, and well-priced homes in the strong school towns still move fast. What changed is how specific the disputes got: Yorkville’s data-center fight is now a lawsuit with a name behind it, Sugar Grove is about to hold a hearing on tightening its own rules, and Aurora already has some of the stricter data-center restrictions in the state. If you’re near one of those parcels, that’s no longer a hypothetical conversation.

If you’re weighing a move in any of these towns, I’m happy to walk through what this week’s numbers mean for your situation.
