Are they communicating with you about why it's not renting, what efforts they are making, etc?

If they have stopped communicating in any manner it could be they fell in Niagara falls and are lost.

Stop communicating with friends, family, etc.

turn out it's just mis communication between broker and title when i decide to change from my name to my llc 

I just have to communicate that I am powered by eXp realty. 

My biggest challenge right now is communicating with my property manager (I’m not local).

However open and honest communication is always good practice.

Then when FEMA starts to come through and the neighbors start communicating they all list their houses with one realtor for the whole neighborhood at a set price/sqft.

(I was wondering if I am just a different generation and needed to revise how I communicate).

If you establish a window of time in which you will be accepting applications, clearly communicate your process and your rental criteria from the start, it's perfectly acceptable to review a batch of applications at the same time, rank them according to your criteria and them process them one at a time until you find a suitable tenant.
