Agents want to be the selling agent 10x more than being buying agents, especially in hot competitive markets. Thus in the current market dynamic, home owners (sellers) should have strong leverage against agents in negotiating contracts.

However the dynamic suffers from a typical experience level imbalance like we see in Venture rounds, M&A deals, etc.

Edit: one challenge with this is that because sellers sign exclusive agreements for sale, you can get the situation common in IPO lead underwriting banks — tell the client the highest price to win the deal, then start the process of gradually walking back seller expectations.
