So, transferring title to an LLC is a transfer as defined by most mortgage or deed of trust documents as a trigger of the so called due on sale clause. 

When a tenant leaves, you document that they are gone, who remains, everyone's rights and responsibilities, how the lease will proceed, etc.

I have all the documentation on this dispute. 

Document all your efforts, including repair invoices and communications, to show you’re acting in good faith as a landlord.
