Eh, I don't know about that, but you're not wrong, either. Because were we to go look at a house today, we'd hit Zillow/RedFin to narrow down our choices, or even pick a single house that fits our needs. A realtor at that point, from the buyer's side, is adding what value, exactly? Now, the realtor can point out a few transactional details, maybe even point out something about that house that we didn't notice (though that's kinda what inspectors are for). Is that worth 5% of the price? I argue a strong "no".
So I would your comment around and agree that we don't need realtors like we used to, but I stand by my statement that one with currently have a rougher go of it without.
