Had I done so I would have save a great deal of anxiety, money, and time because I would have known that he had several federal tax liens and was sued by creditors for skipping out on bills, hires undocumented workers, and sexually harasses female tenants. 

He might even be a better renter, based on his service history.I would personally be apprehensive with convictions for violent crimes, serious misdemeanors and felonies, felony drug convictions, criminal mischief (vandalism), domestic violence cases (with some exceptions), serious theft cases, and sexual assaults.  

"NO sexual or violent crimes" and run a background check.I have properties in FL and AZ so some laws are different.

Shows credit, ok, shows judgments, payment history and says NO convictions.For kicks and giggles, I googled him a few minutes ago and BAM, he was charged  with sexual misconduct with a minor child in March 2018.  

Also any kind of sexual molestation or theft. 

It sounds like you are worried that you may be accused of sexual harassment, assault, or some other thing.

The only ones you read about in the paper are (a) Landlords that blatantly violate the law, or (b) Landlords physically assaulting or sexually harassing their Tenants.The best protection: know and obey the laws, treat your tenants honestly and fairly, and document everything.
