Terminating a Lease in Chicago

[John Hauser]

Hey everyone. We are ready to tell one of not-so-great tenants that we are ending the rental agreement with him (we are at the end of the 1-year lease period). I'm wondering if more experienced folks like @Brie Schmidt or @Mark Ainley or @Ryan Steele have dealt with the procedure for notifying our tenant that we want the property back. For example, I know that the Chicago RLTO requires 30 days' written notice, but do we have to give it personally to the tenant and show service, like a rent payment demand? I have seen some online sample forms, but again I'm wondering if we have to use those or if a letter will suffice? Or a text message? Thanks everyone.
