My part time job is giving them pre-employment drug screens before they can start work. 

@Charles BrownDid you ask your custodian/administrator what they want to see?

My biggest concern though would be the heavy drug use in that area.

Hi there BP members, I am 20 years old and currently self employed through contracts with 7 months of consistent work and am receiving a diploma for Business Administration: Marketing from NBCC this spring.

If ONE unit is vacant and both units are equal in rooms/bathroom composition, then the new owner will need to move into the vacant unit and then the owner can either evict to take the occupied property completely off the rental market (5 years off the rental market), evict to take back the occupied unit for personal use like moving in immediate family (2  years off the rental market), or they can evict given the tenant is a nuisance or conducting illegal activity (this is a harder method to evict since you have to provide evidence and have a case but if they're selling drugs and you have video footage or something, then make your moves) and there are a few other reasons for at-fault evictions. 

A long-time resident at where I'm now living told me when a previous owner (that went bankrupt) started accepting HUD tenants, "that's when the drugs came in" (I wasn't living here then to be able to confirm this assertion, but I have no reason to doubt it).The same reaction happens in business ("street fighting" and "lifeboat ethics").

If YOU present yourself as that representation, its not allowed as you'd personally be practicing law on behalf of the LLC without a license since you aren't an attorney.Same thing goes for administrative actions with the city like building violations, the LLC needs its own attorney.In both cases, you'll usually get a "freebie" court date - IE you show up, tell the judge you are the owner, didn't realize you need an attorney, they'll give you time to get one (a month-ish).

I'm from San Diego, CA and currently work in IT as a database administrator, while also taking classes to get my RE license.  

I obviously don’t condone drug use in the house and don’t want him scaring away prospective buyers.
