I don't see how - and anyway, a buyer's agent can be a big waste of money in a lot of markets. Traditional single-family housing transactions aren't that complicated, and a great many buyers could handle one on their own just fine. I applaud _any_ effort to undermine the NAR.
redfin gets more money with a higher price. And there are some homes redfin will not show you at all because the price is too low (and a middle range where they use "partner agents" rather than their own). And I'm not talking your 5-figure houses in suburbia, I'm talking condos in the city of boston. I have a rooftop pool, fitness center, and concierge in my building, but the price I bought my condo in 2014 was too low for redfin. Meanwhile, my buyer's agent from century 21 got 10% knocked off the list price for me, despite list being 75% of what I was willing to spend.
