Bought a home with a squatter in it. What to do?

[Matt Tobler]

A few days ago I purchased a rental property in Minnesota. The old owner was giving her uncle a place to stay so he has been living there. They never set up a lease agreement or anything. Long story short, I showed up today to check out the house and the uncle comes running out telling me I cant be there and that he has renters rights. He is now refusing to move out and said he plans on staying for the next six months or so.

Is there anything I can do? Does he actually have renters rights considering he was never on a lease and I now own the house?

I bought the house to Brrr and now I'm stuck. Any advice would be appreciated. Thank you
