Owner occupied auction/foreclosure property purchase

[Maryam Safari]

I live in St Louis MO.  I found a few auctions that I want to bid on. I just heard today from another investor that if the property is owner or tenant occupied, It would be hard for me to move them out if they decide to stay and not move out after I close on the house.

Any ideas on what to do? 

Thank you,

Maryam
