Then why didn’t those people set the value higher? If you sell for some price, then you agree that you do want to leave for that price. The “market” would be efficient — people would sell for exactly what they would be willing to sell for. “Sentimental” value could be expressed in actual, taxable value. You could quantify exactly what a house is worth to you — and can insure the home appropriately.

That sounds horrible and very much impossible by definition. The “exact” value of my house where I spent my entire adulthood/childhood is “not for sale”

I keep hearing abouy this market efficiency but never came across a quantifiable measurement of this efficiency. Could you please point me to some literature where they say “oh this market is 70% efficient and that market is 90% because …”? How do you put “exact value” to this efficiency stuff?
