Of course people sell domains for over $1000 and I've sold over a dozen. These days, I don't want to sell a domain for less than 3k, now that I've got a taste for Mid-XXXX sales, but I might if I sense weakness in the domain or buyer.
Is annual profitability important to you? All the domains listed as examples are a crap-shoot. Maybe 1 / 1000 shot, so I suppose if you have over 1000 of these domains you might be able to sell one or more a year for $3k or above. But that's what I'd expect for brandables that are hard to spell or pronounce. 1000 domains x $9 renewal = $9000 a year. So in this example, you'd have to sell three a year just to break even, right? Unless you feel these names are going to increase in value over time, you may want to re-evaluate or try some tricks to cut costs.
