To me, you need all 3 (credit, criminal and evictions).

Unlicensed residential mortgage loan origination activity may subject you to sanctions, administrative penalties, and even criminal charges Let me know if you have other questions

They have a database of potential tenants who are looking to rent properties just like yours, and they screen tenants for eviction history, criminal history, credit, employment history, etc., to ensure I get a good tenant in place, as quickly as possible.  

I wouldn't classify this as a war zone at all but I have responded to criminal violence in the area. 

Make sure to look into addendums you can add to your lease - check out this thread for some more ideas: https://www.biggerpockets.com/forums/52/topics/442...In regards to screening tenants, I recommend having an application for prospective tenants to fill out, followed by a required full criminal, credit and background check.

once I have a potential tenant then I send them a link from Zillow Smartmove and they can apply, this runs their credit and a criminal check on them. 

It's like subsidized wellfare housing. you don't want to be close by as good tenants usually leave and the 'bad' tenants you know the ones who are loud, pack rats, or criminal types stay.

I am interested in hearing feedback on how this could change the screening process.Here's my current screening process:Collect & Verify last 5 years of rental & employment history.Run Checks: criminal, credit, and eviction.Income Requirement: 3x monthly rent (this can be substituted by paying a security deposit of 4x rent)Phone InterviewIn person (or video) InterviewMy rental strategy seems to greatly reduce my risk (eviction, damage to property, vacancy, etc). 

Included in this should be a minimum credit score, income, evictions, and criminal record.

Even if the other person/group is gone by the time the next ones are there, the notice lets them know that there is a demand for the apartment and keeps the showings shorter since they realize someone else may be waiting.On the phone, or via e mail, I go over our requirements (3x rent in income, no criminal history, no evictions) and answer any questions they have.
