No process is 100% foolproof, but if you are not running credit checks and get a bad tenant then you only have yourself to blame. 

You ever meet someone at the cigar shop or country club, clearly very successful and they told you, "I'm just so thankful I learned about Big Larry's Foolproof Apartment Syndications? 

Not fool proof, but better than nothing, I am close to 6' and over 200 pounds, so can't imagine being 5' 2", regardless of strength. 

It's brain dead simple and fool proof) I have a dream to teach and have 1,000,000 people financially independent because of what I tell them on Build a Bigger and Better Life, and I hope they each teach at least 1 person  and ask that person to do the same and ask the same of their students. 

Just saying, don't think of them as a foolproof way of preventing theft.
