simplest answer YOU cannot....
There is no standard commission, there is no information about what various Realty Companies charge, commissions are NEGOTIABLE
Like everything in life, you usually get what you pay for, so to speak.
Various brokerages provide various services, and depending on their marketing efforts, advertising,
and the individual services of the Realtor and price and location of the home, the ease or difficult of showings and marketing the home all could influence what each brokerage will charge as a commission rate, which as you know includes a shared % amount to the brokerage that brings in
the buyer with their agent.
Just ask the Realtor you want to work with, what the company charges in your case and then let
them explain to you what the services include in detail, then decide who you want to work with....
Good luck to you...
