Eviction process
I have looked every where and I just can not find the information I need. I live in Tennessee and I have almost all my ducks in a row concerning an up and coming tax sale with one exception and that is the eviction process. How do I go about having the home owners removed once I obtain the senior lien on the home to make it available for rental? I have spoken with the Clerk and Master and he informed me that I did have the right to evict but that was all the information he had to give. Someone please help. 
Please email me directly by looking at my profile.
I can not speak specifically about Tenn. but I can tell you that I have spoken to friends of mine that are investors. Eviction can be long and tedious process. Putting people out is not an easy task in some areas of the country.
I have been told that you can notify them now of the impending sale and give them 30/60/90 days as a courteousy to move out. If they are not paying you rent, you can start eviction proceedings. The local Sheriff should be able to explain the process. If they are paying you rent, you need to be decent and give them ample notice about your wanting the premises cleared.
If they are squatters, you may have a fight on your hand and every state is different with regard to squatters rights.
I have also been told by other investors that they have helped the old tenant out by finding them a place, or giving them money to move on. Your local realtor can provide insight about local practices.
I know of one extreme case where the new owner got the local Social Services department (welfare) involved and they provided Section 8A assistance because the tenant qualified.
Short of using some muscle, you may be in for an unexpected wait if the tenants have "issues".
Good luck.
