Part 1 of 4

Why a seller cares

The cooperating broker is the buyer's brokerage, and for decades the listing's offer of a split to them was how buyers' agents were paid. That offer no longer rides the MLS, so what a buyer's agent is paid is now in the offer itself.

A simple example

A buyer's agent from another brokerage brings an offer. Their compensation is written into the offer rather than promised on the listing.

Cooperating broker: a simple example
ThenNow
The listing offered a split to any cooperating brokerNo compensation offer on the MLS
The split was the norm, rarely negotiatedEach offer names what the buyer's agent asks for
The seller paid both sides from one commissionThe seller decides, offer by offer, what to pay the buyer's side

Cooperating broker still means the buyer's brokerage. What has changed is how they are paid.

Part 3 of 4

What people get wrong

That the listing agreement still sets the buyer's agent's fee. It sets what your side pays your agent; the buyer's side is negotiated in the offer.
