Realtors inject themselves into a transaction for which they are functionally unnecessary. The agent fee is almost never something they earn by hard work. The most important thing they actually do, is keep the buyer and seller from meeting before the signing so that neither party makes some stupid promise they later regret. It is a pointless job except in that it puts all the real transactions behind a paywall (MLS listings), which they can then snap up good ones before they hit the market.
