Once you decide to sell a domain name, it is important to find the best market to sell it. The best way to sell a domain name is to approach buyers secretly. If you know someone who deals with domain names, it is recommended to contact him without going through the middleman. Chances are that the seller will make more profit, as he will not have to pay the middleman.
When a domain name that was previously registered expires, it goes through a grace period that allows the previous registrant one last chance to reclaim their domain before it becomes available to new buyers. If the previous registrant still has not renewed their domain after the 77 day deletion process, the domain name will officially expire and enter the Aftermarket.
If you are looking to sell a domain name that is no longer of use to you, a possibility would be to lease it through a third-party company such as Godaddy, which lists tens of thousands of names. If the name is a quality one, there are also premium agents such as MediaOptions, which deals with more selective domain names. An alternative option would be to lease it out on platforms such as Nameforest.com. Doing so will save you the time of having to find potential buyers, and will guarantee a higher success rate than attempting to look for a purchaser on your own.

A good majority of web developers view the domain flipping industry with disdain as they face a hard time finding the right domain names for their own development projects. Domain flipping is also looked down upon by corporate and business entities who register multiple domains related to their trademarks or business names. Actually, it is these people who’re the real domain name squatters!

But in general, the best and easy way to sell a domain is to go with a marketplace. There is many popular marketplace dedicated to selling domains including Flippa and SellDom to sell your domain (full disclosure, I’m working on SellDom). The advantage is to leverage the popularity of that kinds of services in hope that someone will find your domain and buy/make an offer.

I've seen some people comment about losing the link value of domains that have expired and picked up, but what about non-expired domains?  Let's say a competitor is going out of business and they still have a year or two left, and we buy their domain and site.  Is there a risk changing registrant info and registrars, even if I keep their site up and mostly the same as before?  I was under the impression that I'd want to keep it under their name so as not to hit the uber-reset button on the domain's inbound link value.
Think about things like contractor.com or oranges.com. The more generic you go, the better off you will be. Why? Research has shown that Google likes generic names, so any company selling oranges may, for example, want the oranges.com domain name. If you own that name, you can set the asking price for it. Sounds great, right? There arejust a few things you have to think about first.

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.
There comes a time in the life of every domain when its ownership must transfer hands. The reasons for selling a domain can vary greatly; maybe the company is no longer being in business, or the domain was bought in bulk and never used. If you're looking to offload your extra domains to make some spare cash, or if you're sitting on a premium domain name worth a goldmine, see Step 1 below to learn how to sell it.
Many individuals have the habit of collecting attractive domain names but never using them. If so, why not get rid of unused domain names and in the process, make some cash? It is important to understand the whole process of selling domain names. On the outside, the process may look very easy, but unless a trader is well aware of how the whole process works, it is not easy to find a buyer.

If domains are real estate, then the same rules of real estate should apply. In real estate, taxes are based on the value of the property. So, a person asking $10,000 for a domain shouldn't be paying the standard $15-30 renewal fee as a person asking $200. The renewal fee should be based on the domain's value. Domainers want to claim it's like real estate without applying the most fundamental rules of real estate.

A rule of thumb that I follow is when I purchase a domain name I have to believe that I can flip it for a 100% profit.  So if I spend $500 on a domain I need to feel like I can sell it for no less than $1,000.  This way, even if I’m wrong in my estimation I still have some room to still turn a profit.  And if worse case comes to worse case I’ve sold domains before for a $0 profit (it happens even to the best of us).
Many non-savvy internet users may not even be aware of the existence of other extensions. That said, because there are many new extensions popping up every now and then, you can often find amazing one word and 3-letter domain names with these new extensions that are otherwise almost impossible to find unregistered in the .com world. Additionally, these new extensions are becoming more and more familiar to users every day, hence it's almost certain that their value will continue to increase as time passes and wider adoption manifests.
