I have found a new agent that I've been working well with and has been able to get me results in a timely manner and really seems to care about my interest and building a solid relationship.

If the answer is don't want them, then from a non confrontational manner immediately advise them you are selling the property and giving them a 30 day notice as you need to prepare it.I am sure Airbnb will not share you anything.However there is a person that is selling his course showing you how to airbnb a property without owning it.  

Additionally, due to some unfortunate family circumstances, my family had to sell some properties in a timely manner and try and 1031 the proceeds.

If you work in a professional manner, the tenants will believe you.  

In that conversation, you can ask some of these important questions in a very conversational manner (so that it doesn't feel like an interrogation).  

You should conform your paperwork according to the manner in which you intend to conduct business which from the facts you have provided is not entirely clear.

Since you don't, I feel compelled to point out those not so nice happenings that I am aware of.

I’ve spoken to many agents and they don’t seem to know any strategy or how to utilize the benefit in this manner.

I'm question is How do we get them to change the property over to a different management company in a timely manner?

We will share the down payment 50/50, and split any profits or costs in the same manner.
