Buying Property. How to remove tenant to make room for myself?

[Tim Kaminski]

I am considering buying a multifamily property in St. Petersburg, Fl.  Would like to house hack but the unit that I would be moving into has a new tenant that wouldn't be out until August of 2018.  

I have heard of the cash for keys strategy, even though I wouldn't know what a reasonable amount of money to offer would be($1000/mo rent).  Are there any other strategies to getting a tenant out of their old lease or do I have to honor it?

Is there anything about changing ownership of the property that would let me kick a tenant out or am I S.O.L.?

Thanks,

Tim
