it can be a double sided sword to a certain extend, without agent, price of property is stay stagnant which is not good for owner, wait till kingdom come, property price still has not appreciate. if overprice, it's a burder for buyer.
best practice for agent is to sell base on market price ( with banker valuation ), that will be fair to buyer and seller.
property is like share, willing buyer and willing selller, no one can be force to sell and buy at a price one fancy.
