Not missing anything, Your great value/asset may be my exit point/liability. Mutually exclusive.
The question I've asked of myself may not apply to anyone else. It's my personal question that I use to determine if there is any additional value in the property. I've been very lucky in that I've never been in a situation where I HAD to sell a property at a loss. I've always sold into these frenzies and been very happy with the result. I miss out on some of the potential gains (Sellers remorse, did it with some stocks in 98-99 also), but, I haven't ended up negative either, knock on wood!!!! The question at its core has nothing to do with the buyers perception of value, only mine.
The perception of value is always a personal one. You are correct in your first paragraph regading the value of an item. Art is a great example of the perception of value. Ever see a painting that just turns your stomach and someone says it's a great work and worth millions of dollars. If you owned that painting would you ditch it to the interested party? It's all in how you perceive the item and it's value.
The market environment/psychology plays a huge part in the decisions I make. With 10 willing buyers for decent properties in todays market, a seller may even get more than they desired from listing a property. A buyers environment requires a significantly different selling approach. IMO, frenzies lend themselves to the 'greater fool theory' and a potential point of exit from the market.
I agree with you that VALUE is a personal judgment.
Just my two cents.
