I’ve got a friend who just listed with a range. He’s pretty realistic, even the top end of his range is a little below the last comp in his neighborhood. He is using a discount realtor and his thinking was that if the buyer comes in unrepresented, he will sell for the bottom end of the range, maybe even a bit less, but if the buyer comes in with an agent that wants the full commission, then its going to be the mid-top end of the range. He subtly communicated this to buyers too.
Last I heard, he has a deal that fit within his plan.
So much for “the buyer doesn’t pay any commission, the seller does” realtor line.
