Internet users, who try to find expired domains and re-register them, will soon discover that this plan cannot be manually accomplished. Professional domain traders are familiar with the registry deletion process and rely on sophisticated algorithms that indicate when a domain is about to become available. Deletion lists are the result of this research. You can find many datasets online with domains that have already become available or will soon be. You often have to pay to be able to see this information.
Use escrow services for direct sales. When you are dealing directly with the buyer, make sure that any money that is transferred goes through an escrow service. This will ensure that all checks clear and that you aren't left with a bounced check and no domain. Escrow services may add a few days to a sale and cost you a percentage, but they can save you a lot of heartache.
We do not only have Expired Domains, but you can also find lists of Deleted Domains for a lot of TLDs. Deleted Domains or Dropped Domains are available for registration and can be picked up for just the normal regfee at your preferred domain registrar! All Domains have the typical SEO relevant data, like Number of Backlinks, Birth Date and a lot more.

There is a misconception that good ‘.COM’ domain names are hard to find and so they are more expensive to buy. But once again, this statement holds no water. You can easily check out the ‘.COM’ domain names that are on sale at highly affordable prices. However, the only downside to flipping ‘.COM’ domain names is that you will have to discover them at different places like or private seller portfolios.

What type of business are you considering of building something on using the domain name?Is it something you believe in and willing to put your all, how much can the monetize with the website, etc..Ask yourself much questions before proceeding to finally selling it.Also, it doesn’t matter if a different company is using a different extension.It means you have upper hand to get their traffic if you build something using the .com.Good luck
Thanks for this post. I do good with Adsense and wanted to branch out so I bought 5 domains from Namejet after reading this thread. After the 5 auctions ended I spent $500 total. I contacted 30 people about these domains and after a few bites I was able to sell one of them for $500 so I got my money back and now what I sell the other four for is all profit. The best part about this is that it is not very time consuming. I spent maybe an hour on Namejet. I spent maybe two hours sending out emails. Thanks again!
Also with the domains, a name which can be cheap for one can be worth gold for the other. Permute the letters in your domain name and try contacting and eventually selling out to organizations that run under those names or contain the letters within. Companies would be keenly interested in buying out the domain names that matches the product's name. Hint : Look for companies on LinkedIn
Acquiring what you believe may be a valuable domain name is the easiest part of the equation.  Finding the right  buyer is much more difficult. Using auction sites and forums is perhaps the best way to find qualified buyers that are interested in your domain, and using auctions will take some of the stress away from establishing the value of a domain name yourself.
Yes, buying existing domain names can be profitable too. Existing domains with a potential for profit can be found using Sedo. Make sure you pick domain names that have good traffic, backlinks and Google PageRank under 17 characters. Also, steer clear of existing domain names containing special characters or numbers because they are not likely to be sold.

The domain name industry is quite similar to the real estate industry in a lot of aspects. There are end users, brokers, consultants and domain flippers or “domainers”. Domain flipping works similarly to buying a house, renovating it (or even sometimes just sitting on it) and then selling it again at a higher price point. The gist of it is: you’re purchasing a domain name and betting it’s worth (or will be worth) more than you paid for it. If you’re right, you get a nice paycheck and move on. Those who make a living out of this just rinse, repeat, and scale.
