If this does not happen the seller could walk with your hard work, equity, and money.

This is a lifelong endeavor.

My question is, if I was to proceed with the Subject To deal, will this somehow be discovered?

It is not about the contact information.

If you have a buyer's agent, you should have already signed a buyer's representation agreement and that fee/commission is disclosed in that document so you should very well know what that charge will be.If you were the seller and going to owner finance the property, what would you want to see from the buyer that tells you that they will be able to pay the mortgage moving forward. 

If you think that the forums and the books have the same information and the same quality, do you read books at all?

As of now, we have zero documents in the portal.

This sounds like you need an attorney to do this.
