Fox Valley Real Estate: Week of July 6–10, 2026

This was a week where the monthly comps mattered less than the dirt underneath them. Rates held around 6.5%, prices kept grinding up 4–5% year over year, and well-priced homes kept moving in the low-40s day range. But the real story out here is land — data centers and master-planned communities from Sugar Grove to Yorkville are reshaping the tax base, the traffic, and now the courtroom docket. Yorkville residents spent the week fighting the build-out in court while the town rewrote its comprehensive plan around it. Here is how it broke down, town by town.

Yorkville

Yorkville is the data-center capital of Kendall County right now, and this week it hit a legal wall. A resident group, Preserve Our Yorkville & Community, LLC, is suing the city and the developers, arguing the approvals strayed too far from the 2016 comprehensive plan and that the traffic, environmental, and property-value studies were inadequate (per Shaw Local). That is the first organized pushback at this scale, and it follows a separate suit the Teska family filed earlier against Project Steel (CBS Chicago).

In response, the City Council unanimously updated the comprehensive plan on June 30, folding in seven approved projects and reclassifying large farmland acreage to industrial and manufacturing, plus a District 115 school site. The projects themselves are enormous: Project Cardinal (1,037 acres, 14 buildings, roughly 17 million square feet, with the developer just asking for an 18-month extension to lock up the land), Project Steel (540 acres, first phase eyed for summer 2027), and a scaled-down CyrusOne campus. On the resale side, the county median list ran about $430K with roughly 43 days on market and around four offers per home (Redfin). New construction along Route 47 is still moving near a $418K median, with Ryan Homes the busiest builder.

What this means: if you own near one of these campuses, watch the lawsuits closely. The tax-base argument is strong long term, but if courts or buyers start pricing in noise and traffic, you could see a real value split between homes near a campus and homes that are not.

Naperville

Naperville stayed firmly a seller’s market. Median list ran roughly $590K to $662K depending on the source, with about 15 days on market, some 52 sales in the last 30 days, and months-of-supply near 0.6 (Zillow, Redfin). The Council is advancing The Residences at Naper and Plank, a 90-unit rental project of 34 townhomes and 56 rowhomes, 1,550 to 1,950 square feet, with an annexation package (NCTV17). Data centers are showing up here too: Karis Critical is floating a roughly 36MW facility (Data Center Dynamics), and a five-story south-end apartment building got approved this spring. For sellers, this is about as tight as the market gets; for buyers, it means clean, well-priced listings still go fast.

Sugar Grove

The Grove, Crown Community Development’s 760-acre master plan at I-88 and Route 47, kept rolling. Area 1 is under construction, with 214 single-family homes on 60- and 70-foot lots along Merrill Road and first deliveries expected this year. The full plan totals about 1,400 residences plus Grove Park, a 323-acre business park that already has a data center under contract, and the TIF is projected to send roughly $135M to Kaneland schools over 30 years (Crown Communities). This is the one buyers will ask about, so it is worth knowing cold.

Batavia

Batavia’s council approved a services agreement with Batavia DC Corp., a Hut affiliate, for a roughly $500M data center, and notably it is traditional colocation, not cryptomining. That is a meaningful add to the tax base without the power-draw controversy. The market held its affordability niche: median sale around $479K, roughly four offers, and homes moving in about 41 to 43 days.

Geneva

Geneva remains the priciest of the Tri-Cities, with median sale around $530K, about five offers on average, and sale-to-list running hot, with a healthy share of homes closing above ask. A new townhome subdivision cleared Council this week. Low inventory is the constant here; historic charm and top schools keep it seller-friendly.

Oswego

Oswego is in a genuine housing boom and leaning into it. Polo Crossing (The Drake Group) proposes 120 single-family homes and 200 townhomes on about 80 acres near Secretariat and Wolf’s Crossing. The Breybourne Cricket Stadium PUD, with a pitch, stadium, restaurant, and hotel, got approved, which makes a nice amenity story for relocation buyers. Longer term, a new comprehensive plan (CMAP-led, wrapping this fall) and a unified development ordinance are in progress, and village leadership is publicly pushing back on the Governor’s proposed statewide zoning mandate (Village of Oswego).

North Aurora

More infrastructure than market news here: the North Aurora Road closure from Pennsbury to Frontenac runs through the end of July on utility delays, with a roughly 110-year-old railroad bridge replacement plus road widening still to come. Flag it for anyone touring that pocket, since access and noise are real considerations right now.

West Aurora and Aurora

Springs at Aurora (Continental Properties), 320 garden-style apartments at Orchard and Sullivan, broke ground, with pre-leasing this summer and first move-ins this fall. And a large new development near Chicago Premium Outlets is in the pipeline, worth watching for how the added supply pulls on nearby resale demand.

County and rate backdrop

The 30-year fixed sat around 6.49% to 6.52% for the week ending July 9, up slightly from 6.43% a week earlier and down from 6.72% a year ago (Freddie Mac). About 60% of Bankrate’s panel this week expects rates to tick up, which is useful information for buyers still waiting on cheaper money. The broader Chicago metro median is near $365K, up 4–5% year over year, and every town on this list runs well above that. Kane County’s median was around $408K, up 7.4% year over year, and Kendall remains one of the fastest-growing counties in the state.

National watch

The big one: the 21st Century ROAD to Housing Act, the largest federal housing bill in a generation, becomes law today, Friday July 10, without a signature. The 10-day constitutional clock ran out from the June 29 presentment, and with Congress in session it enacts automatically. It cleared the Senate 85-5 and the House 358-32. President Trump declined to sign it, calling it “a big yawn” and tying his signature to a separate voter-eligibility bill, but signaled no veto (per NPR, Washington Times, WTTW).

Both sides are worth hearing, and I would treat the industry’s framing as advocacy rather than gospel. Supporters, including the National Association of Realtors and the Bipartisan Policy Center, call it a rare bipartisan supply win: no new spending, streamlined environmental review, more control shifted to localities, easier mortgage issuance for banks and credit unions, expanded access to modular and manufactured homes (the permanent-chassis rule is removed, an estimated $5,000 to $10,000 in savings per home), and a cap barring large institutional investors that own 350-plus single-family homes from buying more. Critics, including Cato, City Journal, and various affordability advocates, argue it is mostly grants, pilots, and studies that need local opt-in to matter, that the institutional cap touches under 1% of the market with build-to-rent carve-outs (Cato goes further, saying it “does not increase total supply, may even reduce it”), and that it does little for the lowest-income renters. My own read is simpler: a law is not a finished home, and out here it is the local councils, not Washington, that decide what actually gets built.

Worth noting alongside it: NAR’s June existing-home report (released July 9) put the national median at $440,600, an all-time high and the 36th straight month of year-over-year gains, with sales up 2.8% year over year. Lawrence Yun argued affordability is “better than a year ago” because wages are outpacing prices, but that national read does not describe our corridor, where prices are still climbing 4–5% on top of an already-higher base.

Where that leaves us

The throughline for the week: a maturing seller’s market up top, a rate panel leaning slightly higher, and a land-use story underneath that is quietly the most important thing happening out here. Data centers are padding municipal budgets and school funds, a strong long-term tax argument, but Yorkville’s lawsuits are the canary, and the value question they raise is real. If you are weighing a move in any of these towns, I am happy to walk through what this week actually means for your specific situation.
