Eviction Tips for Chicago Landlords

[Darren Love]

I live in Chicago and so I wanted to ask for some advice from other Chicago landlords.  My question is about the legal way to give a tenant an eviction letter.  Does it have to be face-to-face or could it be through certified mail?  And if your tenant knows that you want to evict them and is avoiding you, how do you make sure they receive it? Thank you.
