Instead of fretting or getting angry/frustrated, be motivated and smile when you find that new occupant who will be the fresh start you are looking for!

I smile when I see one of my employees financing a new car - I know they have to keep working for me.

Trust me, when you are in the court room, and the judge slams down his hammer, you will have the happiest, warmest smile inside you've ever felt when you win, and it has nothing to do with the money.

What next, let someone rent on 2x and a nice smile?)

@William Morrison and @Chris May -It sounds like it will keep me "smiling".

If there is no bylaw or ordinance against renting it out, just smile and be cordial.

Smiling and understanding, but firm, gave warnings, then 30 day notices.  

Take their money each month, smile, wish them a good day.

Smile.  

You can even get the local Staples or Office Max to accept faxes for you, if you don't have a fax.You smile and hand this form over to the applicant.Then, you also required the applicant to meet you with the animal, so you can take a picture of it and find out in person if it's aggressive.
