Talk the the agent with the broker present and show the broker the e-mails and tell the broker you trusted that the agent had read the form and was advising you to sign it and it was all ok, that is why you have an agent to walk you through the process. 

A week later I am talking with the neighboring property owner who forwards me an email from the same broker offering him the property before it hits the market.

Hello BP,Long time reader first time poster, Thank you for all of the knowledge you have shared over the years! 

They asked me to email them an application, which I did.

That, my dear reader, depends a lot on your point of view and your individual circumstances.

If the agent has a good direct email campaign to other agents, that absolutely can work well.

@Nicholas Hariprasad are you on email lists for wholesalers in your market?

Then call/text/email - any means of communication you have, use. 

BGE has my phone number and email address, but the bills were being sent in paper form to the rental house.

Send me an email.
