Things like writing down your criteria (no rude behavior).

Excuse any misconceptions I may have displayed as I'm still pretty green here.

For  instance  you have to  display cost of  a  PM, Insurance, Utilities, Vacancy, CapEx etc.  

Like children of the Depression, the traumatic events of their youth will influence their attitudes and behavior for a long time.

@Jaylyn Heartso I feel that is unprofessional behavior.

No, it is never too late to change your behavior!

In order to select a good tenant the property manager needs two things: Multiple applicants - If you have only one or two applicants, you are stuck.Financial history - Past behaviors are a good indicator of how people will behave in the future.In Las Vegas, the vast majority of tenants renting properties in the $400/Mo. to $800/Mo. range live cash based lives.

I think the most value is in behavioral economics.

My key point, @Emily Allen is to address the humidity and tenant behavior yourself.  

No one is going to expend resources to research the public records then provide that information free of charge, even if the ads are almost unbearable.One feature of Zillow that is semi-useful is when you target a specific area - city, for example, and ask it to display the pre-foreclosures and foreclosures.
