That's the problem. With respect to first refusal, if you have a property and you want to sell it, it would be very easy for you--and I don't think you would want to be in collusion or do anything illegal--to get me to sign an offer that is four times the value of your property.
Let's assume that your property is worth $300,000. It would be very easy for you to convince me to sign an offer of $1 million. Then you would go to the NCC with my offer of $1 million and say put up or shut up.
