In a sales negotiation for my higher value domain names, I am frequently asked something along the lines of this: “If the domain name is so valuable, why is it still for sale?” The implication is that my domain name hasn’t sold because it is overpriced.
This is a simplistic way to look at it, but it makes sense that this would cross a buyer’s mind. Despite the fact that domain names have had commercial value for 30 years, people are still woefully uneducated about them. It is also a common response tactic to try and get the seller to come off the asking price.
