Lease Expired, what do I do?

[Dominick Marschall]

Hello, 

I have a duplex I plan on moving into tomorrow Oct 1st. However, I have a tenant living there who's lease is done today at mid-night. 

Backstory:

We have a full lease signed by both parties. The lease states it ends today at mid-night. There is a 60 day notice on the lease if either party wants to end the lease. I made him aware that I was moving in on July 31st and sent him a formal 'notice of lease non-renewal' which was the 60 day notice. He acknowledged the fact he would be out today. However, he has not paid me for September rent yet and has not been responding to any of my call/texts. I'm hoping for the best that he is all moved out. 

I will be moving in tomorrow ( I have no where else to go) and do not know what to expect. He may leave some things in the apartment. I really don't know if he's even moved out yet. 

My question: Can I go there tomorrow and if he is not home change the locks and start moving my belongings into the house? If he is not home, how would i know if he just left thing things there or if he is still living there?
