So $1100 is correct, but I would clearly differentiate the charges on any communication. 10% of the rental income as applies to all rental income you ever take in, and $1000 to fill the unit, as applies to any time you fill any unit.

We pride ourselves in giving lower income tenants a higher quality of life, something to be proud of.Also, with them, we make sure all communication is in written form, either text/email, just in case (b/c they are older, easy sympathy story), we have proof they confirm everything is good.

You'll need a registered agent for communications, the thing about these agents is that if any communication is required through them, your cash register will probably ding. 

I've noticed with business especially, most people have completely ceased communicating - it's the time most people are putting all things aside.

@Chris Martin Chris our company develops communications infrastructure including cell towers, distributed antennas systems, fiber optics, etc.

Perhaps the occupying tenant has a forwarding address for tenant b or you can send by mail to your rental unit a communication on the request as tenant b  has likely filed a forwarding address with the post office.

After I tried to communicate with her, she only agrees to get a monthly scooper service, which is totally unacceptable to me.

Unlike some "consultants" or "brokers" who seek to enter into site marketing agreements, we actually have capital and have the full capability to build sites and manage all communications infrastructure for a property owner.Each site is very specific and should be vetted independently, but hopefully this information is helpful.

With todays communications systems the world is a very small place and investors with a team in place in the area they invest do not need to be physically present to operate. 

I also would love to hear about things you don't like or love about an attorney you worked with, ie: he read contracts to you or communicated mostly through email/whatever you preferred.
