In your email, while I do believe after reading it several times that this was your intention, it does not come across this way.

At least that was the intention, and was able to get a low interest HELOC to finish it with sweat equity after we moved in.

My intent is to self manage a small complex.

For now I have a full time job and REI would be part time but my ultimate intention is to get that switched around in the short term.

That is not the intent.

My intention is to network with investors to help increase they're profitability as well as my own, and also to learn the ins and outs of real estate investing in order to become a real estate investor myself.

MLS numbers are very inaccurate in my experience, either due to agents lack of knowledge or intentionally to make the property look better than it is.So to answer your question, if you are arriving at two different CAP rates, look at the detail of your numbers versus theirs. 

@Jeffrey Harden I  prefer to over explain the whole contract with them that way they know the ins and outs of the deal and my intentions.

Other then that, unless you made a verbal or written commitment to work exclusively with him/her, then I don't think there is anything wrong with utilizing the services of another agent.As with everything in life, and especially real estate, disclosure is everything - just have a conversation with him about your goals and intentions so that everything is above board.
