It is very important for all home owners to realize that your real estate agent has many expenses to pay when you list your home! So beating them up on the commissions is most likely not in your best interests!
Take into consideration the cost of their website, the costs to register a url for the home website, ongoing advertising on a weekly basis,print material, time on the phone contacting friends and neighbors, costs to pay someone to deliver flyers in the area, hourly rates for doing open houses if one was to place a dollar value on their time!
It is well within your best interests to consider this when your selecting your agent! Have you ever placed an ad in the newspaper? Its very expensive folks!
