What would you do?

[Gwen Trotter]

Hello ev1. On this "FIRST WHOLESALE DEAL" I am working on, sngl fam 2bd/1b asking $40k, a potential buyer who is a "Broker & Activist" () says he might be interested in buying after he sees hse. He seems to be legit & I'm not questioning his sincerity to help me in this deal BUT, I am concern about how much I'm going to get out of it [b]i[u]f he wants me to have my seller sign a Listing Agreement. He knows I'm new at this and I can tell he is trying to run it his way.
Now, I talked with him about getting a commission out of this deal but I'm worried that I'm not going to make what I could have originally made if I just sold it to another investor. I have other potential buyers but they are not interested in houses in Illinois just in Indiana.
Since I have an elder/senior in my church who wants me to help her sell her condo which is in a very nice gated community for people 55yrs and older and located in a very nice suburb. I don't want to wind up loosing out on a good or great profit twice.
Any suggestion or advice is greatly appreciated asap.
Sincerely,
Gwen Trotter
