It would be smart to list very low if you have friends and relatives interested in buying in the area. Keep it on the DL and don’t even tell your listing broker. But would you want to help your friends? Another problem is that if the broker finds you a buyer, you might owe the commission.
But like I said, on the way up, the confluence of interest, makes the “collusion” almost automatic because everybody benefits (at least for a short period)
On the way down, nobody wants the next buyer to get a deal. Jealously is an interesting human feeling. I personally would rather my friends and relatives benefit than a total stranger.
