Property tax · $751/mo 2.36% of value a year — the ACS 2020-2024 median bill over the median home value for McHenry County, IL

Insurance & upkeep · $409/mo insurance, maintenance and repairs together, from the BLS Consumer Expenditure Survey — the national figure for mortgaged homeowners, scaled to this market's home value. BLS publishes the three bundled and they cannot be split.

Both are priced off the same month's home value, so they rise with the market. Neither is a quote — a specific home's bill depends on its assessment, its age and its insurer.

What it’s like

The place. Crystal Lake is a city where most homes are lived in by their owners, and household incomes run a little above the county's. Residents are of middle age on the whole, and a four-year degree is common among adults. Winters are cold and snowy, with January the coldest month, while July brings warm summer days and the year has a fair amount of rain and melted snow.

Work. Many residents work in schools, hospitals and social care, with manufacturing, professional and business services, and shops also employing a good number. Among the largest workplaces in Crystal Lake are Crystal Lake CCSD 47 Schools, General Kinematics, which makes sieves and screening equipment, and Target. Commutes are fairly long, and some residents work from home.

Things to do. Moraine Hills State Park, a protected area, is a short drive away, as is the Woodstock Opera House, a theatre. The Illinois Railway Museum is also a short drive away. For a longer outing, Geneva Lake is a longer drive away and offers time by the water.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Crystal Lake’s census tracts, against the rest of the country; all of them together, relatively low. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.

From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on McHenry County and the Chicago-Naperville-Elgin, IL-IN-WI metro.
