You'll be sued, have to pay hospital bills and possibly face more civil/criminal charges.And your nice wood floor is ruined beyond repair.

Well, it does until you actually look at who makes up that demand. 95% of that high demand is of low-quality tenants (eviction history, criminal history, no verifiable income, extremely low income, unable to provide a security deposit, or some combination of these).

I check credit, employment, criminal history, court history, personal references, confirm they can get utilities in their own name, and talk with the previous landlord.

The police are trained in criminal law, but are usually pretty clueless when it comes to civil law.I once had a judgment against a deadbeat tenant who moved out most of her things.

Did you do any other criminal background check on this person or credit check history when renting to them??

She also didn't want her boyfriends name on the lease, which i don't have a problem with if he isn't living there but what if he was evicted or has a criminal background

We plan to file a criminal and eviction case.

I did a full background check, credit, criminal, eviction, employment. 

I have a criminal justice and human services background and still work a full-time job in this field.  

Many landlords simply use the court system as a collection agency and count on doing this every month (primarily for your cheaper homes/areas).2) Criminal activity.
