@Steve Dye  I target them by doing pre-employment drug screens to gain access to the refinery in this town. 

Then I told tenants first come first serve especially since #5 told me they couldn't have any peeling paint because section 8 won't allow it and also has her 18 year old son whose on disability living with her and brought a known drug addict to the showing....I used first come first serve to protect me from tenant #5. 

Its to my understanding that denying a applicant for drug related crimes violates the disability act because the government considers addiction a disease. 

I can admit this was not in a great part of town - and the fire department thinks the previous renter may have been some kind of drug dealer. 

He does drugs.

When he's put up adds on FB for roommates, he demands absolutely no drugs, partying, or drama since it is his son's home. 

Basically, if they are "materially damaging" the property or blatantly violating a specific term of the lease (such as if the lease says no drug use but they are using the property for regular drug parties for the entire neighborhood). 

@Joe SplitrockOur bottom unit tenants were heavy drug users with a history of physical abuse. 

a resounding "open it" from the community. next time i'm up there i'll bust it open and post what i find. if it's drugs they're your drugs not my drugs.

So I just received a phone call from a tenant that his roommate is on hard core drugs and does not feel safe in the house and wants off the lease.
