No criminal records, no evictions.  

Do you have a criminal record that includes drug charges or violent felonies, sex offenses? 

Those of you on the land-lording side, what would you do / have you done to "flush" violent criminal tenants from multifamily homes?

Start with the MLS, but get use to having MLS on monitor one, and your chosen title company's title lookup website on monitor two, and of course google on monitor number three to see what "123 Main LLC" is and if that owner of public record is married to someone with a criminal history. 

—In all criminal cases, contempt cases, and other cases filed pursuant to this chapter, if a party has sold, leased, or let real estate, the title to which was not in the party when it was offered for sale, lease, or letting, or such party has maintained an office bearing signs that real estate is for sale, lease, or rental thereat, or has advertised real estate for sale, lease, or rental, generally, or describing property, the title to which was not in such party at the time, it shall be a presumption that such party was acting or attempting to act as a real estate broker, and the burden of proof shall be upon him or her to show that he or she was not acting or attempting to act as a broker or sales associate.

In my estimation, these landlords overpaid for the property, have no experience in what it takes to manage tenants or property, and will throw anyone into a unit, regardless of credit score, criminal background, monthly income, employment history, or rental history.  

What you are suggesting is mortgage fraud, a federal offence.

Prescreening for policy(smoking,pets), income and willingness for background, criminal, eviction checks.2.

Section 8 may be paying all or most of their rent, but that should not affect your credit, previous landlord and criminal background checks.  

The For Sale sign or the realtor's lockbox, along with junk mail (advertising circulars left on the front door knob), are open invitations to the criminal element.
