Chicago eviction question

[Tim Coppola]

I have a situation that I could use some advice on. I just purchased a three flat in Chicago via an FHA loan so I need to move in. There is a month to month tenant in one of the units that I let know on April 28 that they needed to be out by June 15. I talked to them several times over the past month and they said they were still looking but would find a place. Now, I have left two messages over the past week and have not heard back from them.

I'm going to go over on the first to collect rent but can I legally start the eviction process on that day if they do not answer and pay? There is no written lease at all. I'm hoping to get this resolved without legal action but I would like to cover myself in case I need to.

Any advice would be much appreciated.
