Anybody can apply and put false information on the rental application. This is how identities are stolen. Make sure you are doing your due diligence as a landlord and confirm the information provided.
The first step of tenant screening is identity development. Obtain some form of government issued photo identification when accepting an application. Make sure information on the application matches the identification they provide. At this point, you may not even know the name of the person living at your property. The tenant screening report you ordered may be for a completely different person, affecting their credit and reputation negatively.
Always use your own vendors. It's quite possible this guy's "alcoholic brother" is the exterminator working on your property. He'll write a receipt of services that were never performed and now you're reimbursing him. It's another scam that professional tenants use to take advantage of unsuspecting landlords.
He broke a half dozen clauses in your lease agreement? After breaking one, you should begin the eviction process immediately and make sure you establish procedures for screening future applicants, as recommended by @Michele Fischer. Good luck!
