No criminal history (or whatever level you are comfortable with)Speak with past landlords, employers and have a background check completed. 

Oakland bans criminal background checks on potential tenantshttps://www.latimes.com/california/story/2020-01-21/oakland-bans-criminal-background-checks-on-potential-tenants1.

Personally I like the idea, just unsure of the legality of it haha.As far as calling the police generally around me the police hate and sometimes flat out refuse to get involved in tenant/LL conflicts and tell you it is a civil matter and unless a criminal law has been violated there is nothing they can do. 

@Mike MendesI would probably approve if there are no criminal/sex offender records.

You can check the Franklin County court records for any evictions or criminal background and cross reference this with what was on the application and their credit. 

Things I look for, and include in my listing: no evictions or major criminal background issues, take home income at least 3x monthly rent (this is personal requirement, and higher than the typical rent = 30% of gross).  

I just stubbled upon mysmartmove, it charges the applicant $25 to $40 for an extensive screening which includes; credit score, criminal background, eviction history, and bankruptcy.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

The criminal background check came up clear but I found out that the male tenant had case against him that caused him to loose his job at the school due to inappropriate behavior.

Hello,I was wondering if anyone knew any trustful websites (preferrably free) which provide tenants background check report service including felony/criminal charges.
