Not to mention, the value of investor buyers who will only buy at a massive discount is negligible in many respects unless, again, that buyer is willing to be loyal.

Would you change property manager over such negligence?

Assuming that’s the case, do you think  that equates to No or negligible change in the foreclosure market?

I would review and follow its procedure.If it's for cause, identify which clauses/terms in the service agreement that they were in embreach, negligent, etc.Hate to be barrier of bad news about the $500 but that's probably a cost you have to absorb. 

It would be multiple person LLCs -- so they cannot be pierced unless I am negligent, which I am definitely not. 

And unless you can prove it broke due to tenant negligence, the security deposit can't be used to fix it which will leave you on the hook every time.

It's likely going to negligible compared to the overall value of the home itself.one way would be to go back further in time and try finding another large lot sale.

I also say that if the air handler coil starts getting dirty I will know they have been negligent and that they may be paying for a coil cleaning.  

Feeling a bit like my realtor/inspector was negligent and the seller was fraudulent though proving the seller was aware of zoning/building-codes/damage/unpermitted work probably would be challenging even then I'd have to calculate and provide proof of damages. 

you would normally in most states have to be negligent to be found liable for a branch falling on the neighbors property.
