need help with a foreclosed home that has a non paying tenant.

[Jon Mason]

So I bought a foreclosed home in auction and plan on paying for sale tomorrow.. I was in contact with the owner 3 weeks ago that said the tenant has not paid him rent in some time and that the tenant was one of his football players family. I have knocked on the door with no response and left a letter introducing myself to her with no response. I have also talked and left letters with both neighbors introducing myself. my question is after I pay tomorrow what is my legal next step and what is the tenants legal right. I will be flipping this house and do not want a rental. has anyone came across this before?
