Aside from places where you buy and sell domain names, there are some companies around that support the business of domain flipping. GoDaddy is one of the bigger names out there that does. There, you can not only trade domain names but also park those you’ve bought. The buying, parking and selling is relatively painless and all you must give up is a small percentage of your selling price.
So what are some strategies to finding great domains to flip?  Well, the first is to find quality domains.  There are some sights that publish a daily list of good upcoming Namejet auctions like here: http://www.tld.org .  This is an easy way without having to search to find some great upcoming auctions to bid on.  If you have the time you can search Namejet yourself.  The key is to making money by flipping domains is to find domains that other people will want.  If the 30 day window period just started on a domain (for this example let’s say it was Anticareer.com) you could use Google to search for ‘anticareer’ and ‘anti career’ and see if you can find people who own sites that may be interested in this domain.  Email them and ask them if they’d have an interest in purchasing the domain Anticareer.com.  If you get some bites you can then go and bid on the domain and if you win it you can flip it right away.  Once you get some experience it will be easy for you to spot the domain names which you can quickly and easily flip and you’ll also develop a good feel for what price you should pay to make yourself the amount of profit you want to make.
Selling on auction sites is another great way to find buyers. Ebay.com is perhaps, the most popular place to sell domain names. Afternic.com is another site that allows sellers to find good buyers. If you have premium domain names, become a member at GreatDomains.com and list your domain name there. The site is a reputed marketplace and brokers deal with thousands of dollars trading domain names. You can also sell domain names through Sedo.com, a site which has its own selling program. Sedo.com has the largest marketplace in the world, and boasts of having a list of the most expensive domain names in the market. It also has a safe and secure escrow service for domain name buyers and sellers.
Something wise my father once told me "Something is only worth how much someone is willing to pay for it." This small seemingly unimportant statement has guided me in many selling and purchasing decisions in my life. Sometimes, it makes the reality all too apparent. So, is buying a domain with the intention of selling it a good idea? Let's break down the details, and talk to some people that actively pursue this method. Yeah, we know a guy.

As .COM is the natural domain extension for the United States based websites, it does get some priority in the Google.com’s search engine results (based on Google’s US datacenters) when competing against other countries’ domain extensions like .CO.UK, .CO.ZA, .COM.AU etc. However, .COMs don’t get automatic priority over other similar extensions like .ORG, .NET etc. that are also commonly used in the United States. All these domain extensions compete with .COMs on a level playing field.
This is in response to a question a fellow Moz community member once asked in Q&A, and we thought that it deserved its own article. Buying up expired domains, or purchasing keyword-driven domains is becoming more popular amongst the internet "get rich quick" crowd. The big question is: Can you make a profit by buying and selling domain names? If you get the right one, sure. If you plan on repeating the process over and over, probably not.
Hey, what’s up everybody. It’s Brian Dean from Quick Sprout. In this video, I’m going to show you how to buy affordable expired domains and how to evaluate the potential value that an expired domain could bring to your site. Now, expired domains is pretty gray hat, black hat type of thing because there’s basically two things you’re going to do in an expired domain.
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.
There are several types of domain names to avoid. One is intentional misspellings, as these make it less likely someone will search for them. You also want to avoid names with extra symbols like hyphens, or with added prefixes and suffixes like "e" or "my." Outside of a few notable exceptions with very strong brands (like eBay), those additions can only hurt the value.[3]
Above you provided great information about buying and selling domain names. I have been to many blogs about the same and I have read the people make millions just by selling domain names. It's a process that one needs to learn with time and can give a good earning by reselling the domain name. The business is fruitful but one needs to read, understand the value of a domain name. Buying every domain name is a waste of money. One must see the future potential growth for that particular domain.
