The buyer is also paying additional taxes for many years afterward on the higher assessed value (as it includes the commission!).
Well I guess this gets a bit philosophical. Who pays the cost (the actual payment goes from the buyer to the seller’s lawyer which remits a portion to the agent) differs from who bears the cost (called the “incidence” [0]), which depends on the price elasticity of demand versus the price elasticity of supply, and this burden obviously shifts depending on the cycle of the housing market. You are correct that the incidence would fall to the buyer for quite some time now but perhaps this is shifting now.
In some jurisdictions where the growth rate is capped (like CA), a 3-6% drop in price will be locked in essentially forever.
The seller’s agent collects a listing fee for marketing and selling the home. The buyer’s agent collects the buyer’s agent fee for bringing a qualified buyer to purchase the home.
In my understanding there is costs borne by both the buyer and seller for the services of a real estate agent.
This is all important because there's a layer of legalities and agency relationships that the public completely ignores, but is relevant if we're going to have a conversation about commissions. It's also relevant because some states have begun to change their laws to be more in line with what the public thinks happens, which has its own weird twists.
*Brokers and lawyers in the audience will probably say I'm still handwaving away some nuances here regarding agency laws. Mea culpa, I'm trying to keep this simple.
This is the issue. If both sides had to pay their own agent, significantly fewer agents would be used. Instead the buyer externalizes the cost, and many sellers aren’t confident enough to deal with the buyer’s agent directly so they arm themselves with an agent.
