Ethically, I couldn't convince them to buy a house over another one just because it offered me a bonus.  

That's not where money is made, at least ethically.

You will have to take continuing education and be brought up to speed with the laws and ethics, pay your fees, and be connected with a broker who's willing to take you under their wing.

Hello,Let's say a real estate investor is trying to finance a commercial property with investors through an investment bank.If he/she contacted more than one investment bank,and more than one responded back with interest and wanted to do business with him/her further, what would be the right and ethical thing to do for the investor?

It has to be ethical.#3.

I’m looking for a career that I can get the most out of my work ethic and I’m hoping real estate can fulfill that.

They all offer different monthly fees, E&O insurance, charges per transaction, etc.Might be easier to wholesale at first without a license where you aren't bound by the Realtors Code of Ethics.

Since it is an ethics violation to put anything about commissions in the contract I verbally communicate to the other agent that this offer takes in to account no commissions on my side.

As for liability, I can't think of how a real estate license would really create any liability issues as long as one deals honestly and ethically with everyone.

I love to network with people and I believe in doing business ethically.
