Considering where you are coming from I can see your point. However, I work in an office environment where the fax machine is up front by the receptionist so that they can retrieve the fax's and seal them in envelopes for the agent in which it comes in for to maintain privacy. My office holds between 97 and 108 licenses at one time and everyone either has a private office, a quad or a desk. It is a very active office and the chances that 2 or more agents have an interested buyer for one home is very likely. Offers that are faxed overnight are the ones that concern me most. I am no longer gullable to the sharks I swim with in this business. Yes, there is such a thing as integrity in my office and in my community but in the end....everyone is out for themselves. If they are not totally out for themselves they are out to get their client the best they can. And, if they happen to come upon a written offer at the fax machine at 10 O'clock in the evening when they came in to catch up on some paperwork on the same property thier buyer just fell in love with hours before, they are going to take a peak. It is simply human nature. I find it hard to believe that you are not aware of that or don't believe it happens.
If I am representing my buyer to the fullest extent allowed of me I would be presenting the offer personally to the seller on behalf of my buyer. Once in a while you'll get a seller that would rather have their agent present the offer and you have to respect that, especially if they put it in writing.
