Can you inform a tenant their lease will not be renewed?

[Terry Landon]

I have a problem tenant that we inherited from a purchase.

They are causing drama, breaking things and trying to blame it on weather or break ins. 

They called the health dept after they harassed one of my workers and she refused to finish to come back because of her and her husbands behavior so it took longer to finish.  Now they are trying to put their money in escrow over it..when we completed the job already.

I don't know what to do with them. I think they are on lease til August.  Can I inform them that we will not be renewing their lease, and they are welcome to leave anytime as long as given 30 days notice..?
