What's "fairly"?
It seems obvious to me that a fair price for someone who wants to sell their home is categorically different to a fair price for someone who does not want to sell it. Yet it appears this is not at all obvious to a lot of people posting here.
There are things I own that I would never agree to sell for what a "fair market" would pay for them. Their value to me, for reasons of personal connection, memories, sentimentality, uniqueness, or a host of other reasons, means I prefer to have them than any money someone else would pay.
If someone is to force me to give them up, giving me the "fair" price that Value Village would slap on them in exchange is not acceptable. The loss to me is greater than that.
Maybe the people we are discussing in this thread are rich pricks who won the lottery on property values. I don't think it's right to engage in that sort of judgment. This is property they own, and they don't want to sell. If they are to be stripped of it, they deserve at the very least the "fair market value", plus an "unwilling seller" markup (IMO at least 20%), plus all relocation costs (including taxes and legal fees for purchasing a replacement property), plus costs for personal aggravation and distress (IMO at least $10K-$15K). Then we may be in the ballpark of something "fair".
A forced sale is an infringement upon individual rights. In a fair and just society, that cannot be done lightly or without compensation, not just for the property, but for the infringement itself. I'll gladly allow the rich to "win" a little more to protect this principle for everyone.
