No I don't personally, I use this document will all my buyers . I look at it differently after working with buyers over the years I feel it establishes a working relationship where the goals and expectations are clearly outlined. It also puts a stop to wasted time for all concerned. Once a buyer represtentation document is in place, your client can visit Open Houses to their hearts content without being botherd. You are right, of course, about trust and respect and hopefully this will develop with time. To me it's no different then filling out forms at any professional office.
I wish it was the LAW in California!
