Criminal past and eviction history are key, but number 1 for me is looking someone in they eye and making a decision with all of the reports on my tool belt!

Luckily for us, he was out the door as fast as he walked through it.See post above if the attorney for this other poster is correct this is straight out fraud and criminal..  

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.

Think of it this way: if we were to screen tenants on criminal background, credit, eviction history, landlord references, and income (3X that of rent and employee verified), even with 25 tenant applications, it's difficult to find a reliable tenant to match all those criteria.

The only power any government has is the power to crack down on criminals.

When should landlords waive background checks to support Undocumented Immigrants as I am unaware of services that will produce say a criminal background check outside of the United States?

Sometimes a pestering police presence can be a deterrent.If the suspicious individuals are engaged in criminal activity, calling the police while it's happening helps too.

Starting at 43% is close to criminal / fraudulent and not something any experienced investor would ever show.

Title company went for criminal charges not sure what the out come was .. but this stuff has been going on for 100 years.

they are a bunch of white collar criminals, I'm in the process of filing a complaint with the FBI about this company.
