O'Neil Property Group
The western anchor of the US 34 corridor, straddling the DeKalb/Kendall county line—home of the Sandwich Fair since 1888, an 1878 opera house downtown, and typically more land per dollar than the towns east of it on Route 34.
Sandwich is where the US 34 corridor—the Sandwich–Plano–Yorkville–Oswego–Aurora line—meets open farmland. The city of 7,221 (2020 Census) straddles the DeKalb/Kendall county line, with most of town on the DeKalb side, and it’s the community I point buyers toward when the priority is land: many homesites here exceed one acre, and dollar for dollar you generally get more ground than anywhere east of it on the corridor.
The real estate story runs in clear bands. Most in-town detached resales trade roughly $200K–$450K, with attached townhomes and condos from roughly $150K–$250K in mixed subdivisions like Sandhurst. New construction is back for the first time since the 2008 downturn—Ryan Homes is building the 58-lot Fairwinds Phase Four from about $355K, marketed as among the lowest-priced new homes in Chicagoland with included basements and half-acre homesites. At the top of the market, acreage properties and Lake Holiday lakefront run roughly $500K–$1.1M.
The town has history to match. Incorporated February 21, 1859, after local farmer Almon Gage secured a stop on the Chicago, Burlington & Quincy Railroad, it was named by congressman “Long John” Wentworth for his hometown of Sandwich, New Hampshire. It grew as a farm-implement manufacturing town—Sandwich Manufacturing Co., later Plano Molding—and the 1878 City Hall & Opera House on Railroad Street, listed on the National Register of Historic Places in 1979, still hosts performances above the city offices. Every September since 1888, the Sandwich Fair—DeKalb County’s fair—draws peak-day crowds topping 100,000 to the fairgrounds.
As of June 2026, ZIP 60548 shows a median sold price of $321,900, up 4.4% year-over-year—though note the zip includes Lake Holiday lakefront sales, which pull the numbers up. Inventory has jumped from 49 to 140 active listings year-over-year with 68 homes sold over the trailing period, so buyers finally have real selection after the tight 2021–2024 years.
US 34 runs straight through downtown: about 6 miles west of Plano, 13 miles west of Yorkville, and 25 miles southwest of Aurora. IL Route 23 crosses US 34 in town—north to DeKalb and I-88 in roughly 20 miles, south toward Ottawa and I-80. Amtrak stops in neighboring Plano, and Metra’s BNSF line terminates in Aurora, so rail commuters drive to one of those stations. Sandwich works best for people working the US 34 corridor, DeKalb, or from home.
What we’re seeing across Sandwich and the 60548 zip as of June 2026. Zip-level numbers include Lake Holiday lakefront sales, so treat them as a ceiling, not a typical in-town price.
The ZIP 60548 median sold price hit $321,900 in June 2026, up 4.4% year-over-year, with a median listing price of $352,400. Lakefront sales at Lake Holiday pull the zip figures up—compare Plano and Yorkville for the corridor context.
Inventory is up sharply—from 49 active listings a year ago to about 140—with 68 homes sold over the trailing period. After the tight 2021–2024 years, buyers finally have real selection across price bands.
Ryan Homes is building the 58-lot Fairwinds Phase Four—Sandwich’s first major subdivision build-out since the 2008 downturn—marketed from about $355K as among Chicagoland’s lowest-priced new homes with included basements and half-acre homesites.
Most detached resales inside the city trade in this band, with attached townhomes and condos from roughly $150K to $250K—subdivisions like Sandhurst span nearly the entire spread in one place.
The top of the market: acreage properties around the edges of town and Lake Holiday lakefront southwest of the city, where premium lake homes have listed up to roughly $1.1M.
Many Sandwich homesites exceed one acre—the new Fairwinds phase includes half-acre lots as standard. Dollar for dollar, Sandwich generally delivers more land than eastern Kendall County towns on the same US 34 corridor.
From a new-construction restart to a private airpark and one of northern Illinois’s largest private lake communities—these are the Sandwich-area names that come up most with my buyers.
Northwest Sandwich’s marquee subdivision: mid-2000s originals plus Ryan Homes’ 58-lot Phase Four—new builds from about $355K with included basements and half-acre homesites. Resales have closed roughly $310K–$455K.
See Fairwinds Listings →A residential airpark 2 miles southwest of downtown—owners share a private 2,988-foot paved runway (IS65). Custom homes from the mid-1980s onward, roughly 2,000–2,630 sq ft, recent sales about $306K–$450K, next to Edgebrook Country Club.
See Woodlake Landing Listings →One of Sandwich’s largest in-town subdivisions, northeast of downtown—a mix of detached homes, townhouses, and condos built from the late 1980s to 2005. Closed sales span roughly $174K (attached) to $510K (larger detached homes).
See Sandhurst Listings →A private lake community southwest of town (LaSalle County, Sandwich addresses): a 328-acre lake with 8.1 miles of shoreline, beaches, and a marina, established 1965. Most homes trade $300K–$850K; lakefront up to about $1.1M.

Most of the city is served by Sandwich Community Unit School District 430; Somonauk Community Unit School District 432 serves portions of the Lake Holiday area west of the city.
The city’s primary district: three elementary schools, one intermediate/middle school, and Sandwich Community High School.
District 430’s high school, serving Sandwich and surrounding portions of the 60548 zip.
Serves portions of the Lake Holiday area west of the city, along with Somonauk itself.
The 430/432 boundary crosses the Lake Holiday community, and rural parcels around the city can fall in either district.
Note: District boundaries here cross municipal and county lines, and school assignment can change from one parcel to the next—especially around Lake Holiday and on rural acreage. Always verify the current school assignment for any specific address directly with the district before you buy. Our team can help clarify.
DeKalb County’s fair, held at the Sandwich Fairgrounds every year since 1888, the week after Labor Day. Peak days top 100,000 visitors—more than a dozen times the city’s population—and it’s still the thing Sandwich is best known for across northern Illinois.
Sandwich City Hall & Opera House, built in 1878 in the Second Empire style and listed on the National Register of Historic Places in 1979, still stages performances in the hall above the city offices—a working 19th-century venue, not a museum piece.
The commercial core along Railroad Street grew up around the 1859 CB&Q rail stop and the farm-implement works—Sandwich Manufacturing Co., later Plano Molding—and it remains a working downtown rather than a themed one.
Edgebrook Country Club’s par-72 course sits on the southwest side of town, bordering the Woodlake Landing airpark—golf and general aviation share the same corner of Sandwich.
The private 328-acre lake southwest of town—8.1 miles of shoreline, boating, water skiing, fishing, beaches, and a full-service marina, reserved for members of the property owners’ association since 1965.
Three reasons come up over and over: land, price, and the return of new construction. Many homesites exceed an acre, in-town resales start around $200K, and Ryan Homes’ Fairwinds restart means you can finally buy new here—from about $355K with a basement and a half-acre lot—for less than most new builds east on the corridor. Nobody moves here for the commute; they move here because the trade is worth it.
Most in-town detached resales trade $200K–$450K, attached homes roughly $150K–$250K, and acreage or Lake Holiday lakefront $500K–$1.1M. The June 2026 zip median of $321,900 sits well under what the same house costs in Yorkville or Oswego—and the lot is usually bigger here.
US 34 through downtown puts Plano 6 miles east and Yorkville 13; IL 23 runs north to DeKalb and I-88 (roughly 20 miles) and south toward Ottawa and I-80. Amtrak stops in neighboring Plano, and Metra’s BNSF line terminates in Aurora, about 25 miles northeast—so rail means a drive to one of those two stations first.
Sandwich sits across two counties—and Lake Holiday adds a third—so tax bills, county records, and school assignment all depend on exactly where a parcel sits. Lake Holiday is a private association community with mandatory dues (verify the current schedule with the LHPOA), and attached-home segments in subdivisions like Sandhurst may carry their own fees. We verify county, district, and association status on every property we show.
Our office is at 201 E Veterans Parkway in Yorkville, 13 miles straight east on US 34. We work this corridor every day. We know which side of the county line a Sandwich parcel sits on, which addresses feed which school district, and what land is actually worth per acre out here.
We track each 60548 closing—in-town resales, Fairwinds new builds, Lake Holiday lakefront—so our pricing opinions are built on the full data set, not a zip-code average pulled up by lakefront sales.
With Ryan Homes building again at Fairwinds, we guide you through the builder process and negotiate incentives on your behalf—at no additional cost to you.
Professional photography, strategic pricing, targeted marketing, contract negotiation, and closing coordination. With Sandwich inventory up sharply this year, those first 48 hours online matter more than ever.
From acreage on the edge of town to lake-community holds, we provide honest analysis of what property along the western US 34 corridor and rural Kendall County does—and doesn’t—return.
Our Google reviews tell the story: responsive communication, local expertise, and results. We earn referrals by delivering a level of service that national platforms and discount brokerages can’t match.
