Many newbie domainers go on a buying spree excited by all the reports of high sales and opportunities presented in the industry. But as you know high prices fetched by individual sales don’t always show the market price and finding end users may turn out to be much more complicated.
By selling, or at least trying to sell a few domains once in a while you can get a better understanding of the market and current prices. Even if you are a buyer, and planning to invest in a few good domains to hold them for a long time, listing them for offers on a domaining forum can you get a good idea of the market price. This can also be useful if you need to sell the domains quick to raise funds – you’d already know what price you can expect for a quick sale.
