It is inevitable that full disclosure will rule the day. There was a day when brokers used to drive potential buyers around neighbourhoods to view properties, then brokers would list open house in newspapers, then the Internet came around and people could educate themselves BEFORE going to a open house or sales centre, thereby helping both the buyer and broker in dealing with a qualified buyer situation.
Come to think about it ... We also used to drive in cars without seat-belts, have a couple of beers and get behind the wheel, think a sun burn was a good thing on the way to getting a nice suntan.
It is called evolution. Education and disclosure will rule the day in the not too distant future and we will all be asking ourselves what all the fuss was about. Education equals intelligence - certainly we want an educated public when dealing with what will likely be the most important and largest ($-wise) investment most of us will ever make.
