Right now one of the realtors we've interviewed takes 5% and offers 2.5% to the buyer's agent. Not much better. They also offer 4% if they are a dual agent.
But I know of cases where a buyer without an agent got the seller agent to accept 4% overall while only representing the seller (but handling the paperwork necessary to complete the transaction.) That 2% was a worthwhile part of negotiating, allowing the buyer to get a lower price.
* If I were a member of the public, I'd be more upset about referral fees than commissions. This is a far more grey / nebulous area of real estate compensation. We have to disclose and discuss commissions up front, but referral fees are often in the shadows and definitely can cause buyers / sellers to pay more.
