Fox Valley Real Estate: Week of August 10–14, 2026

Rates ran the show this week. The 30-year fixed sat around 6.69% on Freddie Mac’s weekly read and roughly 6.70% on the daily gauges — the first stretch in about 44 weeks that we’ve been above where rates were a year ago. That mattered more nationally than locally. Across the Fox Valley, inventory stayed tight enough that pricing power hasn’t cracked: well-priced homes kept moving in the low-40-day range, sellers held near 99% of list, and the long-term story — data-center and master-planned money landing in Kendall and Kane — kept reshaping the value map faster than any single month’s comps. Here’s the town-by-town.

Naperville

Still the tight, fast anchor of the corridor. Average value ran about $636K, up 4.4% year over year, though the median sale price actually eased slightly to around $590K (Redfin). Supply is the real story: roughly 232 homes listed, down about 19% year over year, 0.63 months of supply, around 43 days to sell, and a 99.47% sale-to-list ratio. The split by type is worth watching — detached is softening (median off about 2.9% near $675K, sales down 11%), while attached and townhome product is hot (prices up 4.3%, inventory up 70%, August sales up 17.6%). If rates have squeezed your budget, the townhome segment is where the movement is.

North Aurora

The most genuinely this-week item in the valley. North Aurora Road reopened August 3 between Pennsbury Lane and Frontenac Road after the widening phase — but it’s slated to close again this fall for the roughly 110-year-old rail bridge replacement, a project that runs into late 2027. The eventual payoff is two lanes each way, a center turn lane, a multi-use trail, and a sound wall. If you’re showing or buying in that corridor, factor the closure into the timeline. Separately, Orchard Gateway Blvd laid its first asphalt layer around August 10, and the Silverleaf subdivision was re-scoped from 115 lots down to 99 — bigger lots (minimum 9,500 sq ft, averaging 12,250), a quality-over-density shift toward more move-up product.

Batavia

The Tri-Cities value play. Median around $479K with roughly four offers per home and a 41–43 day pace, with the $400K–$650K band seeing the strongest demand (Redfin). For buyers who like the Fox River and downtown feel but can’t get there in Geneva, Batavia tends to run $30K–$50K under comparable Geneva homes.

Geneva

The walkable-downtown, Metra, Fox River darling — and priced like it. Median near $530K with about five offers per home and a similar 41–43 day pace (Redfin). Inventory sits near a month, down from about 1.4 months in January, so it stays competitive for anything priced sensibly.

Sugar Grove

The Grove keeps advancing. Crown Community’s 760-acre master-planned community — town center, 200-plus acres of open space, mixed housing, plus a roughly 323-acre Grove Park business district at the I-88/Route 47 interchange — moved forward after this spring’s annexation and zoning work, with a TIF district and development agreement approved and a data center already under contract in Grove Park. For a town of about 9,400 people, that’s a meaningful long-horizon swing in value for nearby owners. It cuts both ways: resident pushback over traffic, pollution, and school funding continues, and that’s a fair concern to weigh, not dismiss.

Oswego

Two sizable residential projects are in the pipeline: a 160-acre mixed-use plan (125 single-family, 243 townhomes, 288 apartments) and another ~345 units (219 townhomes plus 126 single-family) south of Wolf’s Crossing and east of Douglas. Both run under the modernized Unified Development Ordinance adopted in 2024, with a fresh 2026 zoning map — a cleaner entitlement path for builders, which usually means more supply reaching the market on a predictable schedule.

Yorkville

The one to really watch. Two data-center campuses are approved — the roughly 1,037-acre Project Cardinal (Pioneer, up to 14 buildings, ~17M sq ft, 1.8GW) and the 540-acre Project Steel (Prologis, 24 buildings), with Steel’s phase-one construction eyed for summer 2027 (Data Center Dynamics). The developer package brought about $51M in upfront payments to the city and roughly $68M toward school-district expansion — a real near-term tailwind for services. But resident pushback stays loud; one Shaw Local account quoted the sentiment plainly, “nobody wants to live in data center row.” If you’re buying near the Route 47 corridor, know what’s going in behind you — the schools money helps, but 40-plus industrial buildings are an open question for long-term resale. New-construction median in town runs about $418K.

Aurora / West Aurora

Firm but affordable — average around $324K, up ~2.7% year over year, which keeps Aurora the value entry point for buyers priced out of Naperville and the Tri-Cities. West Aurora listings (SD 129 footprint) averaged near $374K, running about 67 days on market versus 47 a year ago — more room to negotiate than most of the valley. Downtown momentum continues with Keystone Lofts (33 luxury apartments plus retail) and a 9-acre campus redevelopment, and Ares’ $70M purchase of a 356K sq ft industrial facility on Sullivan Road reinforces the jobs base under all that housing demand.

County & rate backdrop

Kane County logged 203 residential sales in a recent week at an average around $478,505, with a countywide median near $382K. On rates: Freddie Mac’s weekly figure held 6.69% (week of Aug 6) and daily gauges sat near 6.70% through Aug 13 — flat, but for the first time in about 44 weeks, above year-ago levels. Fannie Mae’s forecast still points to roughly 6.4% by year-end, which is a drift lower, not a drop.

National watch

Two data points landed this week. July CPI (BLS, released Aug 12) came in at 3.4% year over year and up 0.1% for the month, with core at 2.5%; shelter did about two-thirds of the monthly increase and energy fell 1.5% on the month but remains up 14.7% year over year. The doves’ case: the print was in-line and the headline cooled to 3.4%, which CNBC framed as giving the Fed “more breathing room” ahead of September — room for rates to drift lower. The hawks’ case: 3.4% is still well above the 2% target, core is sticky and ticked up, and shelter is doing the work, so a September cut is far from settled; Cleveland Fed’s Beth Hammack argued “now is the time to act.” Reasonable people read it both ways.

The day before, NAR reported July existing-home sales fell 1.7% to a 4.06M annual pace (up 0.7% year over year), with a record median price of $434,100 and the 37th straight month of year-over-year price gains. Lawrence Yun called sales “remarkably stable” and said the market “would be thriving if rates returned near 6%.” Worth taking with the appropriate grain of salt — NAR speaks for sellers and agents, and “record price” is a seller’s line. The skeptic’s read is just as valid: sales are still near multi-decade lows, record prices plus high-6% rates are exactly what’s keeping buyers on the sidelines, and “rates just need to fall” has been the industry’s pitch for two years running. A buyer working a deliberate plan is being rational, not missing out.

The bottom line

The through-line this week: rates finally sitting above where they were a year ago, a local market still too tight to give on price, and a development map that keeps redrawing itself out in Kendall and Kane. Price sharp and the valley still rewards you; price like it’s spring ‘25 and you sit. If you’re weighing a move in any of these towns, I’m happy to talk through what it means for your situation.
