When someone's trying to sell you something, they're usually on their best behavior.

The disability community is speaking up against the rise in people misrepresenting themselves and their animals, as such behavior is hurting people who have qualified disabilities and legitimate service animals.Good luck.

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

This irritates me too, but I had to let it go.You can put language in your rental agreements about guest frequency and behavior.

Having this type of behavior from the tenants is just unacceptable in my opinion. 

I believe your behavior has taught her it is okay to pay late.

A co-signer does not guarantee good behavior, or zero damage, or zero noise, or zero people parking on the lawn or smoking in the house, or bringing in pets or having loud parties, on and on.  

When showing the house, I try to tune in on the prospects, listening to the questions they ask, what they say and watching their behavior.
