Should I take my tenant to small claims?

[Thomas Grove]

At the move out inspection meth paraphernalia was found.  The unit tested positive for meth and was condemned by the health department.  $7600 later to have it decontaminated and replace everything permeable I am wiped out many years of cash flow.  I am now in the negative owning this property for 3 years.

I have evidence of the positive test and photo evidence from the move out inspection of the parapheniala.  However, I did not test this unit for meth when I bought it which is where I questions myself on winning in court.  

Do you think I have a case?
