My uncle has worked in the court systems and in general as a psychologist with sex offenders and people with sexually deviant behaviors most of his career (30+ years). 

On top of that, what if all of a sudden you need a new roof, or windows, or a sewer line, or the irrigation system freezes, leaks and floods the basement, or a fire guts the place and your insurance only covers some of the vacancy/rebuild costs, or a flood washes it away and you didn't have flood insurance, or your tenant stops paying and their estranged lover/stiffed drug dealer breaks in and destroys the place, or any one of a myriad possible bad things happens because you have an investment that hinges upon human behavior, and therefor needs constant baby sitting, and 5 years of your glorious $500/month is wiped out in one afternoon, and the bank takes the property?

As the property condition and tenant behavior becomes known to us, we can often reduce the number of full inspections to no more than once a year.   

Think certain freezers, coolers, affixed displays etc. 

Said it could put the property in jeopardy if there was any criminal behavior Since it’s still illegal on a federal level, not worth the risk.

I have created a Google Chrome extension that boosts your property browsing experience, by offering filtering abilities on displayed properties (if you don't know what a google chrome extension is, its an app that runs on your browser instead of on your smartphone).I have big plans for this mini app, and I need your help in validating I am in the correct direction.

Positive rental history since the time of eviction is one way to demonstrate a change in behavior.

If the tenant resumes the same behavior again file much faster to avoid two months of not collecting rent.

You're essentially rewarding the bad behavior to escape a greater loss and then dumping them on the next unsuspecting Landlord.

I figure the prospective tenant "should" be on their best behavior during initial interactions with me (just like a job interview).
