If you mean estate agent fees, it will depend where you are and the price of what you are selling.   Between 2 and 4% is the norm.  Technically they are set by the local Chamber of commerce, but in practise that isnt the case. 

If you mean Estate agent fees, it is also possible to negotiate, 3% would be common, but some acceted  discount and settle for 2%
