There are probably more real esate agents per capita in my area of Florida than there are anywhere else; we are one of the fastest growing areas in the nation. I was a real estate salesperson and a broker in the late '70's-early '80's; I only got out when interest rates were so high no one could afford to buy, then I found something I liked better.
My son, while working professionally as a real estate appraiser (and a regional appraisal manager for a national bank) is a licensed broker. My best friend is a Realtor, and has been since 1977. I know buyer's agents, listing agents, dual agents, residential, commercial, farm and land, beachfront specialists, and just about every flavor of agent you can think of. Our Mayor is a Realtor, our state senator is a Realtor, and my barber has a real estate license.
I have never met a low life swindler, an exceptionally greedy or crooked real estate agent! I have met some dumb ones, and some incompetent ones, but I have never met an agent who would deliberately do anything to hurt the client. The dumb ones can lose the client a lot of money through bad advice, but they don't make much themselves, and they don't last in the business.
Why? This area lives and breathes real estate sales. If an agent did something to screw up a deal on purpose, it would be common knowledge very quickly. It has happened, but only rarely. It's much more common for builders to accept down payments then abscond without building anything.
Bob, I'm afraid that either agents eat different food up there or something, or you have been very unlucky, for you to get such a jaundiced view. With so many of my friends working so hard on their ethics, it hurts to see you make such blanket indictments. I agree that you should interview several, but that's only to weed out the dummies.
