The difficult part is usually with the City, but State regulations can be tough to navigate too. 

., that seems to be an issue with the 3rd party appraisal company rather than the lender. 

Did you appeal it yourself or hired a 3rd party? 

We have been burned a couple of times now, I used checkthem.com to screen before and it didn't show multiple evicitions on either party, after the aforementioned tenant's recent eviction, I am screening once again. 

This could be interpreted as practicing law which all agents need to avoidHowever, in my opinion it does not effect the lease at all as once the lease expires a 30 day notice by either party would terminate the lease@Jerel Ehlert While I understand that the 30 day notice is necessary after a foreclosure, I believe that does not apply to the owner if they are still in the property. 

I need an opinion from disinterested party......I’m involved with a debate between contractors.

The question I have is if all parties involved agreed that we sign a written contract voiding the existing contract ending on 10/30/2018 and then have the existing tenant that wants to stay and the new tenant sign a new contract, why wouldn't that work?

First, you can't terminate the lease until the natural expiration date or until all parties agree.Other than that, I would just write a simple letter explaining your intent.
