Living in Collinsville: what buyers should know
The feel
Collinsville is a city in Madison and St. Clair counties, Illinois, near the Cahokia Mounds State Historic Site and home to the 170-foot Brooks Catsup Bottle water tower.

Local rules most buyers miss
Occupancy inspection: Collinsville requires a residential occupancy permit and a city inspection when a home changes ownership; the seller applies at least seven days before the title transfers (a home can be sold as-is if both parties file the as-is form, shifting repairs to the buyer). Confirm current requirements with the City of Collinsville Community Development Department (618-346-5200).
Property taxes: Illinois assesses homes at one-third (33⅓%) of market value, and your bill depends on Collinsville’s combined Madison County and local levies. Illinois property taxes run noticeably higher than Missouri’s, so tax is a major line in your monthly payment — don’t estimate from a national calculator.
Closing note: Illinois charges a state and county real-estate transfer tax when the deed is recorded, so budget for it among your closing costs.
