They have not responded to my communications since they left. 

Quote from @Frank Barletta: Is 3% really that tough to give up for providing most of your guests, extra insurance, customer success, payment processing, communication, etc etc etc?

They do not communicate once you’ve informed them of how they screwed up.

Just sent her back her money with an email saying her lease is cancelled due to an obvious impending lease violation she revealed in her communication.

Poor communication, long delays, big mistake.

I plan to move back to India soon and was wondering if at all it would be possible to remotely manage my properties from India (12 hour time difference makes real time communication a lot harder).

Communication and consistency are key.

@Evelin Negrete - If you don't want to manage tenant communications, hire a virtual assistant for $5-7 dollars an hour and have them take tenant inquires.

Typically you do not need to do it as a double closing, you can do it in one closing you just need to communicate with the owner of the property during that time. 

In my experience, once it gets to the no communication stage it usually never works out
