Now you have the choice to bring in a buyer that IS being represented by REALTOR (broker/agent). That commision charge for representation has no "normal" range. Negotiate.
If you agree to little bitty number for the buyer ONLY to be represented, be prepared for a lot of work and quite possibly no one looking out for your best interest.

Do some math- your asking price (then their offer if/when it comes in) minus the commission. Now compare that to a professional CMA from a local realtor (what they feel your home is worth and would list it at) minus their commision. Consider also, that if you list with a selling agent before any of this goes down, you would get much more exposure being listed on the RMLS, and will be seen by many MORE BROKERS WITH BUYERS. (Generally speaking, many REALTORS don't have the time, or make the time to fish around for FSBO's on a regular basis!) It is notable that you are excluding your home from a whole other market.
