I did self manage and self lease, so I screened all tenants looking for no evictions, no criminal background, good landlord references, long term tenancy, etc.  

I also check the court records (civil, criminal & traffic) myself, just in case something was missed.  

We require any tenant 18 or older to qualify for whole rent on their own unless they are a legal dependent (spouse, college student, dependent parent, etc) of applicant, even then must pass criminal background check.

The trend in larger cities has been for less police and more leniency with criminals.

I have transacted at least 5000 properties as a flipper developer and lender and I have had one instance of this. were someone recorded a mortgage 5 minutes before my loan went on record so when I got my title policy I was in second instead of first made a claim to my title insurer and they rectified it quickly and went after the bad guy criminally. 

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.

I think this is proven that even in ponzi criminal case, if asset has good valuation and the law is being done properly, we will get our money back as investor.

For example a tenant has to meet certain qualifications to be able to rent your property: income, credit score, evictions, rental history, criminal history, etc.

As stupid as my step mother is even she wouldn't go for it unless she and her criminal minded sister coinspired together again my father to strip him of his pride which is what shows and I have factual evidence to back my verbal statements and arguments against those who took advantage of a hardworking man who provided everything for his loved ones.

This should be treated as criminal behavior
