But what if you want to stop prostitution, drug rings, and shootings?

You have the right to refuse to rent to people who you refuse to make their intentions clear, or refuse to people who change their story.We've had several situations exactly like the one you described where a restaurant owner rented an apartment for employees and we've have a few where massage parlor owners were using our apartments for prostitution and we had serious problems every time.I would not go as far as taking the rental off the market, but you may feel better documenting every conversation, text message and picture.

They are really cracking down on drug houses and prostitution in that area. 

@Bob RomanoIf he is still paying rent and not at his former job, as long as he’s not selling drugs or prostituting himself at your property, who cares.

If the guest disturb your neighbors in the middle of the night with music or anything, or smoke, or drug or bringing prostitutes to your place, etc... there is no compensation and basically no penalty for the guests.

Now walk a few blocks from that area, you get into areas where you wouldn't want to be at unless you are looking for drugs or prostitutes.

Primarily I try to stay away from gangs and areas with visible drug and prostitution activity.

I will say that if I see open market prostitution or drug operations then I probably wouldn't do the deal.

Then, my second guest ever brought a prostitute over (different story) so I almost quit.
