Interview a bunch of areas and see what realtors are offering. If you are a seller then see what they are offering for their commission and take it from there.
Hope this helps.

In any case, commissions are negotiable as Paula has stated. You can expect that, if you are listing a property, you might want to conside the efforts involved in the transaction, as well as the range that others might be paying in considering what commission rate to offer. Sometimes land is different than a building, commercial different than residential...there is no set rate.
The short answer is that all commissions are negotiable. I wish I could give you a range, but even that might be considered "price fixing"...a huge no-no. I would suggest that you call a few agents in your area and ask them what percentage they expect to receive for their commissions. After a few answers, you should have a pretty good idea of the norm. Good luck!
