It’s a mistake to think that the real estate commission is primarily for paperwork or executing transactions that would have happened anyway.
I brought my house to our agent and pushed the sale through. That’s probably a rarity when I think about all the time friends of mine have spent with agents “house hunting”. That time costs money and to a great extent, the fat commissions are paying for a lot of “no commissions”.
People seeking to disrupt the “fill out the final transactional paperwork” part of real estate need to figure out how to disrupt the whole value chain, not just the part that looks outrageously overpriced.
