The fastest people in my feed assume a buyer network means your pool, and it usually means someone else's pool you happen to get routed through.
A case worth sitting with: say a ten-person group pools buyer lists and a deal comes in at 140k, ARV 210k, repairs estimated 38k. The math clears for three buyers in the list. Two of them belong to one member, one to another. The deal routes to the first member because she sourced the lead. Her buyers pass because they are already carrying two rehabs. The deal dies, or goes back for a price drop, or the clock runs out on the inspection period. The second member, with the qualifying buyer sitting idle, never got a routing call. Nobody wrote a rule about routing sequence when the sourcing member's buyers decline, and that blank space is what killed the deal, not the price and not the market.
What actually holds up in groups that close consistently is a tiered routing clause: sourcing member gets first right to match their buyer within a defined window, 48 hours is common, and if no match, the deal opens to the pool in submission order with a second defined window before it goes fully open. Without those two windows written down, "pooled" just means the fastest phone call wins and the deal still depends on one person's relationships.
The question I want the room to answer: does your group have a written routing sequence, or is routing still a conversation that happens in a group chat after the contract is already signed?
