Purchase triggering property tax reassessment Cook County IL

[Zach Click]

What is everyone’s experience with a property tax reassessment upon sale of a property? In Cook County, IL, my understanding is you may or may not trigger a property tax reassessment based on a sale and otherwise it’s somewhat unpredictable when an actual human will come to reassess the exterior and interior for overall value.

Trying to predict when this might occur on a property purchased with currently low property taxes but is subject to significant increase when reassessed due to forced appreciation. Thanks!
