Evicting a tenant after tax deed auction

[Steven Payne]

Need help with a unique situation. I bought a property from a tax deed auction on Tuesday and the next day I received a call from the police department asking if I was planning on evicting the current tenants. The original owners of the home past away and the caretaker has been living in the house. The water has been turned off and the meter pulled because they have not paid the bill. Three other "drug dealing" families may be living there as well. The code enforcer for the town has let them know that it is illegal to live in a house without running water. My question is, does this give me grounds to evict them sooner. There is no prior lease agreement. The officer said he would even go with me when I make my visit. Any feedback would be appreciated.
