Is the luxury niche defensible because of the network or because those buyers are indifferent to rates

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 that is hard to square with the rest of the story about this niche. One reading is that the moat is the network. An agent who knows the twenty families who could write the check on a $6M house, and knows which listings will exist before they exist, holds inventory and buyer access that the next licensee cannot copy. 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 large 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 capable for a couple of years. That is a market condition, not a moat. The two readings imply different things about what happens when the high end cools. Networks survive a downturn. Rate indifference does not help when the wealth effect turns and the same twenty families decide to wait. The open question is how much of the high-end buyer pool is genuinely all cash versus cash-like closings that get refinanced afterward, and that number likely decides the answer.
