Bought a 3flat Need to remove problem tenant. NW Chicago IL

[Mario Jay]

Hi Guys,

Good afternoon!

I just closed on a 3flat in the NW suburbs of Chicago. The building is completely rented currently. However, I purchased it with an FHA loan and want to move into the top floor unit.

 Per discussion with the prior owner the top floor tenants only paid half of the rent for May (bad news) and refused to pay them the full amount. Now it's my problem. The tenants only have a month-month lease. I am trying to get rid of them ASAP and am willing to call the forgone rent a loss. Would I have to evict? Tell the current tenants to get out at the end of the month? I am not sure what my options are or where to even begin.. Thanks for the help!
