I think the "most important" depends upon the situation. For example, while i agee with Michael's assessment that marketing skill are important, I don't think a potential buyer gives a hill of beans about marketing plans. Likewise, and forgive me here, being personable would mean nothing to the buyer or seller in a really crucial juncture in a transaction.
In essence, I think the three most important traits needed depend upon what the actual situation calls for. One trait I think is essential, however, is RESPECT (and there is far to little of it in either real estate or mortgage financing...IMHO).
Respect for self (I will represent myself with honesty and integrity and ethics because that is who I am).
Respect for all customers, clients (understanding my job is to accomplish THEIR goals, not mine).
Respect for colleagues...internal and external (there are a lot of people involved in the process, each has their job and role to do...they deserve respect in the process).
Respect for ALL real estate professionals in the transaction (this one has always been important to me. I recognize that I hold their commission and possibly their livelihood in my hands with every transaction. I do not take that responsibility lightly).
Thanks for the question. You have given me the basis for a incredible blog post!! Best to you!
