Earlier quoted context omitted.
I grew up in Chicago and love Chicago, so I'll try to say this as politely as possible - don't expect your property to hold any value in IL. Anecdata - I have friends that lived there for 8+ years, then moved to the south in the last 2 years and their property value barely budged.
I honestly won’t be too upset if that happens especially if it means people aren’t treating housing as high return investment vehicles. Hopefully that means house prices will be more reasonable.
Note - there is a reason housing prices in Chicago are stagnant...people are leaving.
