Hi @Ruark Adam Barrientos I think the most important thing in real estate investing is building a team early! I am sure you hear it a lot, but it can't be stressed enough. Try to find handymen beforehand, vet out a bunch of lenders, talk to property managers in the areas you are looking to invest (they are great sources of local knowledge and may be used in the future!)
Investing in Illinois is tough because of taxes, as you mentioned, and the fact that it is not the most landlord friendly state. That being said, there are still some parts of IL that can make sense for rentals. I know the Fox Lake/Round Lake area seems to still cashflow decent and if you are looking a bit farther south try places like Joliet or Aurora.
If you are looking for appreciation same principle applies. IL as a whole definitely won't be awesome, but some markets will still work. Know your market! Generalities don't work in this game unfortunately. Good luck!
