Your grandparent is talking about buy-side agents though -- as a buyer-only brokerage, our experience is that high priced transactions are usually easier to deal with because finances are more buttoned up and the deal is less emotional. The thing that is genuinely harder and more expensive with the higher priced sales is customer acquisition. At Open Listings we started with a flat-fee model but quickly realized that we were excluding lower priced transactions and not able to make the margins work for acquiring buyers at the higher end. Instead, we now refund 50% of the commission, so while it's not as good a deal for the uber rich, we think we're able to grow faster with more marketing dollars in the system. A deal is only good if people know about it and we've been able to refund a ton of money back to buyers this way. When we've reached a critical mass my hunch is that CAC will drop and we'll be able to drastically lower our commission or go back to working for a flat fee that's more reflective of the costs to do the transaction.
