How to kick a tenant out of a multifamily?

[Christian Laines]

Hi BP,

I believe I have found a good deal doing my analysis on a multifamily. I plan on living in one side and renting out the other, or as we call it "house hacking." 

The only issue is that both units are currently being rented. So my question is, how do I go about getting a tenant out of one side? Would this even be legal and right to do? If so, what would be the "right" thing to do?
