What are the typical qualifications for a recruit in the Realtor army? And if you are a buyer, how effective is your personal army for you when it only gets paid out of the booty collected by the enemy?
And regarding the dentist analogy, if my dentist got his degree as a result of taking a couple of classes at a community college, and the work he did for me was purely form driven (http://www.winforms.com/) and cost $40k a pop, I would do it myself.
That said, most folks are probably not inclined, or prepared at all to do it for themselves, but they should at least be driving hard bargains with the agents they hire, and should be asking tough questions at every step of the way, considering the large sums forked over (and financed over 30 years w/ interest) for RE services at today’s price levels.
