Property tax · $312/mo 1.92% of value a year — the ACS 2020-2024 median bill over the median home value for Madison County, IL
Insurance & upkeep · $209/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. Collinsville is a city in Madison County, Illinois, on the Missouri side of the Mississippi River region's metro area. Incomes here run below the county's, and the town has more renters than many of its neighbors would expect, though most homes are still lived in by their owners. Winters are cold and summers are hot, with a fair amount of rain and melted snow through the year.
Work. Many residents work in schools, hospitals and social care, in shops, and in professional and business services. Collinsville CUSD 10, the local school district, is among the largest workplaces in town, along with Fairmount Park Casino and Racing. Unemployment is a little lower than it was a year ago, and the county has added jobs over the past year.
Things to do. Cahokia, an archaeological site, is a short drive away, as is World Wide Technology Raceway at Gateway, a race track. A longer drive brings you to Gateway Arch National Park and the Saint Louis Zoo, both well known across the region.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Collinsville’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 Madison County and the St. Louis, MO-IL metro.
