Maybe, if OP would just listen to other members' comments here, there is still a chance that the buyer might contact OP immediately. How about because the price he wants to happen is a bit unrealistic and OP doesn't seem to see that?
Probably because he doesn't care it's his price after all. If someone make a deal for it's a win-win for them. Besides it uses a broker this means, broker will get a percentage or fixed commission for this sale, that's why its too expensive.
If OP is still care locking this thread and create a new thread will help, this thread become haven of spam, the redundancy of replies/post sucks.
