Quick answer: it is negotiable between the buyer and seller who pays and how much.
Following the settlement of the NAR lawsuit involving various class action cases nationwide, Multiple Listing Services (MLS) are now required to adopt certain rule modifications, including the following:
#1 – Buyer agents are now required to establish a written agreement with their clients prior to showing any properties. This agreement must specify how the agent will be compensated. Buyer agents can receive payment from their clients, the seller, or a combination of both.
#2 – Buyer agent commission is no longer allowed to be posted on the MLS. This compensation is now a negotiable aspect of the contract, similar to the property price or any other contract terms. Brokers can still share the commission as they did previously, but it cannot be listed on the MLS. Sellers can choose to pay the buyer's agent a commission, but this arrangement is now negotiable among the seller, buyer, and buyer's agent. There is no requirement for the buyer to pay their own agent. You have the freedom to determine the commission for your buyer's agent, including the option to offer no commission at all—it's entirely up to you!
