Marengo is a city of about 7,568 people (2020 census) in McHenry County, with a typical home value of about $368,000 as of Sept. 30, 2026, according to Zillow. It’s a small town with room to breathe, and it’s a lower price point than many places closer to Chicago.
I’m Dana Gallagher, a Broker with Berkshire Hathaway HomeServices Starck Real Estate. I help buyers and sellers across the Chicago suburbs, and here’s my honest look at living in Marengo in 2026.
Where Is Marengo, IL?
Marengo is in McHenry County.
Marengo sits in western McHenry County. U.S. Route 20 (Grant Highway) is the main east-west road, Illinois Route 23 (State Street) is the main north-south road, and Route 176 also serves the city.
The town was first called Pleasant Grove, and its post office, opened in 1841, was named Marengo after the Battle of Marengo. A train station was built in 1851 on the Galena and Chicago Union Railroad, the first railroad west out of Chicago. Passenger service ended in 1950, and in 1967 the old depot was moved to the nearby Illinois Railway Museum, where it’s still used.
Marengo Home Prices in 2026
| Marengo, IL | Zillow Home Value Index (Sept. 30, 2026) |
|---|---|
| Typical home value | $367,952 |
| Change from a year earlier | Up 6.7% |
With a smaller market, the median can swing from month to month, so I look closely at recent sales near the exact home you’re considering.
A median is just the middle sale. Size, condition, lot and location can put a home well above or below it, so I always pull recent sales on your exact street before we write an offer.

Neighborhoods and Housing Types in Marengo
Homes in Marengo range from older houses near downtown to newer subdivisions. For the 60152 ZIP code, Realtor.com showed a median listing price of about $380,000 in May 2026.
Schools in Marengo
Marengo has two public school districts. Marengo-Union Elementary School District 165 serves pre-K through 8th grade across three schools and includes the neighboring village of Union. Marengo Community High School District 154 runs Marengo Community High School. Confirm the schools for any address, especially outside city limits.
Parks and Things to Do in Marengo
Next door in Union, the Illinois Railway Museum is a big local draw. Marengo’s downtown sits right where Routes 20 and 23 meet.
Annual Events in Marengo
Marengo Settlers’ Days turned 55 in 2026 and ran October 9 to 11 in downtown Marengo, with a carnival, a car show, an arts and crafts fair, a children’s pet parade, Saturday Night on Main Street and a Sunday parade. Marengo’s original 1851 depot now sits at the Illinois Railway Museum, where it’s the oldest railway station in regular passenger use west of Pittsburgh. The Kishwaukee River runs along the north edge of the city.
Local Employers and Economy
The City of Marengo lists major local employers including Nissan/Logisnext forklift manufacturing, Thomson Linear, Engineered Polymer Solutions, Arnold Engineering and Marengo Tool & Die. For recreation, the Marengo Park District runs Indian Oaks Park, a 140-acre facility with a fitness center, pool, sports fields, skate park and trails, and the city maintains Calvin Spencer Park northeast of downtown.
Commuting from Marengo
The big change for Marengo commuters was the I-90 interchange at Route 23, which opened on December 23, 2019. It was the first interstate interchange built in McHenry County and closed a 17-mile gap between interchanges. Marengo doesn’t have a Metra station. The closest Union Pacific Northwest line stations are in Crystal Lake, Woodstock and Harvard.
By car, OpenStreetMap routing estimates about 62 miles and 85 minutes to downtown Chicago and about 47 miles to O’Hare, without traffic. Rush hour will take longer, so test-drive your commute.
Property Taxes in Marengo
Outside Cook County, Illinois counties assess homes at 33⅓% of market value. Your actual bill depends on the combined tax rate for your parcel (village, schools, park and library districts and more) and any exemptions you qualify for.
I pull the real tax bill for every home we look at. My property tax guide explains how Illinois bills are figured.

Who Is Marengo a Good Fit For?

My Tips for Buying in Marengo
- Get pre-approved first. Sellers want to see you’re ready. Here’s why you need a pre-approval before you buy.
- Confirm the school assignment for the exact address. District lines don’t always follow town lines.
- Look at the real tax bill, not an estimate.
- Time the commute at rush hour before you fall in love with a house.
My Tips for Selling in Marengo
- Price from real sales. I pull recent Marengo sales by home type, not just the town median. Start with my free home value report.
- Prep before you list. Small repairs, paint and clean photos help a home stand out.
- Know your tax and HOA details. Buyers ask, so have the latest bill and any association documents ready.
- Plan your next move first. If you’re also buying, read should you sell before or after you buy.
