Real Estate business is a big sham in my opinion. The commission structure is unfair and out of control especially in the U.S. 6% is standard in places like California what a joke for putting a house on multiple listing and making in many cases with the price of housing, $60,000 commission up. That is a year salary for many people but agents put in a few hours work.
Here and everywhere, they should get paid by the hour same attorneys.
I would try to negotiate as low as possible. They put your property on a website, show it, and help with paperwork I doubt most put in 40 hours on any transaction. That is about it making 60 to 100k for what?
A sham joke.
