Just to clarify, so that I do not get crucified any further (@Dan Kistler): I HAVE NOT MADE THIS OFFER!
I am bringing it up for discussion because I know negotiation wise it is a great strategy, but I had strong hesitations due to the obvious ethical dilemma. I believe you never hurt yourself by over communicating, so I know how I will move forward with this negotiation.
I guess the true question is: When is it acceptable to use your greater knowledge in a subject to your advantage? For example: If a house flipper wanted to be completely transparent with the person they are buying the house from, they would teach the seller how to flip the house themselves. By not disclosing to the seller how to flip the house themselves, they are withholding valuable information from the seller. Does this happen? No, because the house flipper has a greater knowledge in the subject and uses that to his advantage.
In my original question, my greater knowledge is in contracts and financing property, so is it acceptable to use that knowledge to my advantage? I think for me I want to operate a transparent business and therefore honesty is very important, but I thought this was an interesting discussion to have.
