For now, I would not communicate any further with this person until we can confirm his identify, but I'm 99% sure this is a scam.

I thought i was communicating what Jason Bott says above. 

Any solution is going to need to integrate with the existing remote technology to which you will likely need to attach some piece of 'hardware' to it in order for it to start communicating with the world. 

I'm trying to navigate how I should communicate with them that I am planning to put it on the market. 

The Housing Authority was not helpful at all and had really poor communication.

With a competitive market you need an agent who has good communication skills and can write offers that stand out.

Immediately send written communication to all contacts you have and can find with their company that you are canceling the contract immediately.

I send communication to the tennant call him, leave courtesy rent notice, but nothing.

I hired them to renovate my multi fam full reno. have ye to start the work but i'm impressed with their communication and professionalism. 

I did not communicate enough about the small things because I was too worried about the contractor thinking I was a pain, but in the end, resulted in me having to ask them to go back to the property to address them in three waves.I shouldn’t let the small things worry me so much.
