Is the luxury niche defensible because of the networks or because those buyers don't care what rates do

The Redfin work showing buyer-agent commissions at the luxury level ticking slightly lower after the settlement, while fees on cheaper homes held or went up, is the part I can't square with the rest of the story about this niche.

One reading is that the moat is the network. The agent knows the twenty families who could write the check on a $6M house and knows which listings will exist before they exist, and that inventory and buyer access is what can't be copied by the next licensee. Under that reading the slight fee pressure is noise, because the thing being paid for is access and it stays scarce regardless of percentage.

The other reading is that the niche looks durable mainly because its buyers are less sensitive to financing. If a big share of high-end deals are cash or done on private and portfolio paper, then volume at the top holds up while the mortgage-dependent middle of the market stalls, and every agent working the top looks like a genius for a couple of years. That's a market condition, not a moat.

The reason I care is that the two readings imply different things about what happens when the high end cools. Networks survive a downturn. Rate indifference doesn't help you if the wealth effect turns and the same twenty families decide to wait.

I'm still working out how much of the high-end buyer pool is genuinely all cash versus cash-like closings that get refinanced afterward, and I suspect that number decides the answer.
