Additionally and in the alternative it was unnecessary for the landlord and/or his agent to make a house call to procure payment and the tenant is not liable for consequent costs arising. 

Is there a "living conditions" section... meaning the tenant must keep their unit in good living condition and must report things like leaks, mold, cracks in walls, etc... immediately or face X consequence up to and including eviction.

Your leases signed by the PM should have been signed Joe Doe as agent for your name.If you were attempting to keep in anonymous background, then a new lease is the consequence of allowing the PM total signature authority. 

Someone acting on reliance of the information you provide could face extreme adverse consequences, and disclaimers will not always protect you.DISCLAIMER: None of the above shall be taken as comprehensive analysis of the law in any one particular state.

The only consequence for me as a landlord has been that when a new tenant arranges to have utilities switched back on, a utility might call me to verify the previous tenant isn't still in the unit and trying to trick the system. 

What is the consequence for the PM if their leniency doesn't pay off?

As a consequence newer owners will have to increase rent to equal what previous owner was profiting from.  

If parts of your lease are not strictly legal, are there worse consequences than simply those specific clauses and any actions taken based on them being invalidated?  

Everything in life has a cost and a consequence.

Hence, you would encounter serious karma consequences, if not legal ones. ;-)
