If, upon obtaining a judgement in an unlawful detainer, the tenant does not vacate the premises, follow the law and have the sheriff assist them in leaving.If there is more to the story, do tell please. 

This is referred to as an unlawful detainer and usually, you have to file something to get them out, but the rules depend on the state's and county's laws.

So far you've risked nothing but you have an opportunity you can leverage into meaningful experience that will help you next time if this one doesn't add up.I've seen situations like this where the house represented such bad blood, the seller wanted to lose money to punish his ex.Good luck!

what that means that if they have had an eviction, I may require 2 months rent as security deposit, but I know as long as I don't give the many room to be late and  I send my 5 day notice right when the rent was late, and file my unlawful detainer, I can usually have someone of the property in less that 60 days (hence double security deposit).  

why waste your time trying to punish him, just see what you get as a result of your discovery
