Buyer upside?
That depends if you’re selling wholesale or retail and if you decide to factor in holding time and opportunity costs.
I think the key if you were to ask those in a position to truly know, the answer from @DomainKing and the @Castello_Bros would be that the domain has to truly pencil out for the buyer in a clear manner.
For estimating a domain name's hold time, understand the difference between a microwaved hamburger, an oven baked souffle' and a fine aged wine. Different tastes, different budgets and different hold times.
