As people have said, there IS no rule that applies everywhere.
And depending on how you value your own stuff, you may never be able to sell at a price you consider fair.
Just as an example, I know I would never be able to find a "fair" deal for all of my stuff, because I would want 2-3 years of gross revenue. That seems fair to me because I know what the financial history and future is - because I've spent 12 years (offline and then online) building a brand name, dominance in a niche, customer awareness/loyalty, and traffic, and know without doubt what ballpark my income will be for the next 3-5 years. But a buyer would never be able to "justify it" to himself or his investors without that same background/knowledge/certainty.
I think the key is whether you are "personally invested" in your stuff, or whether it's just goods to be bought and sold.
