Would you recommend one partner provides more cash and the other partner is responsible for the previously mentioned duties?

Additionally, the trust language should designate a substitute trustee who would have taken over the trustee duties after your mother passed.  

Am I missing anything vital?

In the meantime, I have not finished either project because of Military duty in Korea has not allowed me to return as I intended to get the mx completed.

I am also active duty military so if there are military investors in the area, let's chat!

You have to blend figuring out how to do things , or share duties among people.

First, I didn't see if you were active duty or not but that might have a little influence on the decision here.  

Even when a variable rate commission is offered, the discount is typically 1% or so, not the entire amount of the other side, as the agent needs to perform the duties for both sides of the transaction.  

It is particularly useful when tenant laws are unfair to the landlord... like France.I'd suggest you think about all possible scenarios (tenant moving out early, landlord failing his/her duties to repair...) and what markets you would get into.

They have a duty to their shareholders and in many circumstances a duty to the previous owner to maximize recovery and mitigate loss.
