As far as the listing side of the commission, anywhere from $295 for a flat fee, no frills, to 4% of the sale price.
Most properties--even short sale or foreclosed properties are offering at least the greater of $1,500 or 2.5% of the sale price to the "buyer's" Realtor.
The important thing is that your listing agent pays the extra fees to Realtor.com so your home is "pre sold" before a buyer ever steps into your home. Some Realtors do not pay the extra fee and have a very limited description and no extra photos. Go to Realtor.com and put in your zip code to see how competing properties are being represented by Realtors.
If your property is worth at least $100k, it may be worth paying a licensed appraiser to give you a current market value. That way you may not make a serious error by either overpricing or underpricing. Some listing agents may overpromise with an inflated market value to "buy" your listing and alternatively some listing agents may lowball your market value to facilitate a quick and easy sale for the listing agent. The $300 you will pay for an appraisal may be money well spent because it may save you thousands of dollars because you will not be influenced by the pricing promised by some listing agents.
Hope this helps.
All my best,
