As the property owner, you need to make sure your property is habitable as defined by public standards. 

I think it is crazy to require all applicants to have 3x rent, it should be household income for the people that will be living in the unit.You can make the strongest wage earner the primary tenant, the person to stay if relationships fail.If I were you I would change my personal income standard and look at maybe adding other standards that reduce your risk of tenants not following through, such as looking at how long they have had their jobs and how long they have co-habitated.  

However, even with good screening habits, the occasional bad apple will inevitably slip through.

People tend to try to play down the importance of problems by saying things like "everybody does it", which allows them to keep their bad habits, but getting involved does not usually work out.

They'll just say they picked up the habit though.

Fortunately, the place was habitable and sanitary since there was concrete underneath so I had the right to continue charging rent.

Just letting you know that wholesalers (at least some of them) can bring good deals and you don't want to get in the habit of biting the hands that feed you.
