This is an interesting story happened this January. A domain that I had brought for $3 in a forum sold for four figures in just six months. Unfortunately, I cannot reveal the exact sales price as it would violate ToS of the marketplace, where I sold the domain.
Here is the story.
I hop around a lot in a domain forum called Namepros. The forum is undoubtedly the best domain forum on the web. In l July 2015, while browsing through a sales thread I came across a domain by name Peopledom(dot)com. The domains listed with auction starting price of $3 among other brandable names by a seller. While people were bidding for other listed domains, no was bidding on it. Curiously I put first bid because of it sounded unusual and I felt like bidding. Anyway with that opening bid of $3 I won the auction.
For a month or two I tried to sell the domain for $25-$30 in the same forum. Nobody took interest in the name. The other day I came across a marketplace called Brandbucket(dot)com, which I learnt later, as the best place for trading brandable domain names. I decided to try my luck. I submitted around 10 domains for listing. BrandBucket rejected the 9 names except one. Guess what! The only accepted name was Peopledom(dot)com. I paid further listing fee of $10, which Brandbucket charges for each accepted domain.
Honestly, I was not expecting sale of the domain. So, I completely forgot about the listing. One day I received an email from Brandbucket to my Whois email informing me that the domain has been sold for four figures. The interesting part is that the domain was sold one week before and the marketplace team sent numerous message to my Brandbucket registered email, which I did not bother to open as I was not expecting the sale. Immediately, I concluded the sale and obviously was very happy that my only listed domain got sold.
In nutshell, I had invested $13 for the domain (purchase price of $3 + listing fee of $10) and got ROI of thousandfold. Now I have around dozen of brandable names listed in Brandbucket marketplace.
So what is the takeaway from the story? You might ask.
Well. As a domainer we mostly use the tricks and learning we had while picking up domain names. Only very few domainers use their instinct/intuition, which often regarded as not scientific. But in my personal opinion instinct and intuition are very scientific because they are based on our unique experience. They are result of our subconscious mind and would prove correct sooner or later. I believe I listened to my intuition and purchased the domain.
