And I think you've proven that you're a realist as I see it as a tremendous ROI.
Bought for $20, sold for at least $4000 or maybe more...
This would make me feel really good!
no offense guys but "realistic" is starting to sound a lot like a euphemism for "chicken".
whats good about a "tremendous roi" if in fact one is passing up the opportunity for an even more tremendous roi. its rather obvious that 40k is 10x better than 4k. imo opinion 4k was a domainer price, something that you should have got if you needed cash right away and flipped it here. if thats the case then you did the right thing.
but in the long run success comes down to the courage to turn away loball offers and stand your ground. if you belive that interested buyers will balk at paying those levels then you will always be selling yourself short and leaving potentially life-changing sums on the table.
every situation is uniques and has to be weighed on its merits. naturally when a fellow domainer offers you a certain amount and says they wont/cant pay more than you probably ought to belive its true, more or less, and if you feel its fair and want to move on then thats fine - take the roi and let them assume the risk at the higher purchase level. we all know that corporate offers dont come that often. this is as true in .com as anything, in .tv its even more rare to see corporate offers though they do seem to be increasing.
large corporate buyers often use agents or otherwise obfuscate their identities so i always assume until proven otherwise that any inquiry is a very interested and very well off buyer. and any midsize company thats needs a particular name will in fact pay up when they firmly understand that they cannot get the name cheaper. but they will keep trying to get it cheaper until they do firmly understand this.
if a buyer tells me they are a small outfit or a nonprofit i say "prove it". i've even given names away to bona fide non-profits when they do and i like what they are up to.
domains are substantial business assets whether they are .com, .net, .tv, or .wtf. i dont care what the name is or how i feel about it, if someone knocks then they must have their reasons for wanting it and i have to assume they are valid and commercial in intent. over the years i've turned away a lot more offers than i've taken and in the end i belive i've come out far ahead. thats realistic.
