The problem is their fee is also that much. So it doesn't benefit you to get 6% higher price if you have to pay it to agents. It's just more tax and fees you have to pay on a higher house price.
That's not true, the agent fees come from the seller's money.
It's only true if you consider your employer to be paying for everything you have in your house, because they gave you the money you used to pay for your stuff.
