I just got a new complex and one of the apartments has a cat in their room I was not told about. The Lease states no pets, however the previous manager said that apartment is his best as far as paying rent. Lease does...

(Source: Portland Urgent Care - and about every allergen and sinus clinic in the country).Your failure to manage to the lease after knowing that there was a cat on the premises could prove to be a defense should you offset the security deposit without having receipts from credible/industry trades with their findings noted. 

They may seem nice, but so did Bonnie and Clyde.They are simply attempting to rent an awesome house for $800 less than what it is worth and being 100% dis honest about it.

This happens often and makes it very easy for dishonest folks to steal from you.  

When your first assumption is that the PM is dishonest and should be fired without knowing the facts of the situation as you have here, you are giving bad advice.

Sad thing is: there are lots of people that act in dishonest ways in all walks of life.

That means he/she has a fiduciary responsibility to look out for your interests first.That doesn't mean that the PM can treat the tenant unfairly or dishonestly, and they certainly have a duty of care to the tenant regarding health/safety and  livability issues.

That might make them feel that you are dishonest and then you still have to live with them.

Their being dishonest?

It's hard to believe how dishonest a certain segment of the population is until one experiences it.
