I've only ever sold a few properties myself but as I understand it, yes you can discount-list or even flat-fee list a property but the agent that represents the buyer typically still expects to get 3% from you.

It has amazed me that we have been in a technological age for a long time now where buyers can pre-select what they want to see and don't need more than someone to open the door for them at a property, and sellers don't need anything more than a way to get their property on the MLS yet they continue to give up a total of 6% of the sale to an agent.

That 6% amounting to $10K or so on a "median" house in the US seems not incredibly out of range given how much effort along the way results in no sale, but in a major city it can reach $100K or more for the same amount of work. The competition to be a selling agent must be fierce.

Overall it makes local moving relatively costly and can chew up a disproportionate share of any investment gain if that's your angle.
