Is there course to teach Real Estate Agents how to work with investors?

[Belinda Lopez]

Or a good online article?

Yesterday I was in the office of a broker with over 20 years as an agent. She said she had never heard of 'wholesaling' properties. I explained how we as investors work directly with sellers/owners, get the property under contract for a price, then market to our investors/buyers for a higher price, then make the assignment fee. She was clueless; said she never heard of assigning a contract and how could I market a house I had not bought? I explained I had it under contract which gave me an equitable interest, then the end buyer is buying my place in the transaction for a fee. Again, she was just bewildered. I've come across this over and again so does anyone know of a good article or course to send agents to that will help them understand this process and learn that it's not illegal?
