If the sales commission numbers come down into the 2% range, then I'd be more inclined to use a traditional realtor, but it still feels like WAY too much money. If you sell a $500K house at 6% that's $30K out of your pocket. If you sell one for 2% that's $10K.
I think that the service of 1) helping take pictures of my house and put it on the MLS, 2) showing the house when people want to see it, 3) hoisting an open house or two, and 4) helping with the process and paper work of handling the offers and counter offers, and 5) helping with the process and paper work handoff with the title company to help make the closing smooth is valuable but worth a LOT less than $10K.
By comparison, if you pay an attorney to estate planning for a fairly complex Trust, wills, all that crap, you'll pay less than $10K, and that's for the time of someone with a J.D.
I think a fair price for what I described above is less than $5K.
