I actually should have explained this along with my original post.The property is actually owned by my Solo 401K Trust with me as the Trustee.  

You certainly want to explain your deal.

If they see a big deposit in the statements that you are required to send, you're right, you will have to explain where that money came from.

Again, while I can not say whether or not this was clearly explained to you I can say it is common practice and seems odd you would give a deposit and continue looking for other properties. 

My previous CPA also didn't really specialize in REI and I found myself explaining things to him sometimes.

I see no way to contact them and explain its NOT SPAM. 

If you turn them down (say, when you have your own capital), you may be seen as the selfish one for not including them on your deals (even if you try and explain the rationale, good luck)...Today's privileges are tomorrow's demands, as the saying goes. 

That by explaining to people your purpose , people genuinely want to help you out.

If you have investors who are willing to take over a contract without seeing it, then more power to you.I explained to your employee that we were new to the Florida market and that we had not established local team in this market yet. 

I think when you can explain to anyone how and when they get there investment money back plus whatever return you or the deal offer.
