There is a rough backstory  -- tenant has been a PITA since day ONE and her attitude and behavior are continuing to escalate.  

Your bandit sign should more prominently display your message and have your logo as a smaller piece of the overall real estate.

Do not reward bad behavior.

You can definitely require proof of current vaccinations, alteration and a behavioral report from the doggy daycare.

I said I wouldn't file this week.Also the reality is the notice to pay move is to reel them back in because they have gotten out of control on rent and other behavior.

Screen well and screen for behavioral issues and abuse of phone numbers should be a relatively rare event.

I know that I am loosing money on the occasional bad guys but this is way better than loosing money on 50% of my rentals and the bad tenants get reported to the courts and hopefully when the next landlord checks their background he/she will not rent to them so they'll pay for their bad behavior.

Learned that the hard way.Plus, a co-signer does not guarantee good behavior.
