Thank you for the nice summary,
@Rajuajoshi - I would agree with this:
While there are certainly rules of thumb that are right some or even a lot of the time, depending too much on rule of thumbs not only misses out on opportunities but also will lead you down paths that may not be profitable. If domaining could be reduced to 6 or 7 rules, then a bot could totally dominate (or is that happening
). Also, I think that your summary demonstrates that we don't all need to follow the same path to success, and in fact it is good that we don't.
But the central answer to OP is that one domain not selling in 6 or 7 months is not unusual, it is the norm. Those who write articles and books that say "flipping domains for easy and fast profit" are, in my opinion, misrepresenting the ease of making money with domain names.
The strange thing to me, is some names that do sell. I go through the NameBio list every day, and there are always names that sell, sometimes for $$$$, that I think most would say are poor names according to conventional thinking. So why do they sell? I think it is partly that domain names sell in all languaes and cultures, and some that seem strange to a western English speaking investor may be strong if your first language is something else.
But really, it takes one purchaser who sees value in the name, so if I was to hold onto one rule of thumb it is handle names that could potentially be used by multiple realistic end-user.
It is true that if you are selling to other domainers, and want that liquidity, following the common simple rules of thumb helps find buyers.
