You may find yourself at one time or another needing to sell a domain name. You may have registered a group of names or a bulk lot of names and find that you no longer need all that you bought. There is a solutions for you if you would like to sell the name now and make a small profit rather than waiting for your renewal date and just not renewing.
Basically what you need to do is become a domain name registrar reseller. Most domain name registrars offer a reseller program. They will allow you to buy bulk names at a discounted rate and then you sell them and make a small profit on each. The domain name registrar takes care of the registration and the customer support. This is to your benefit because all you need to do is round up people who want to buy domain names.
Domain resellers are very competitive. By lowering prices it helps domain names remain affordable for just about anyone who wants to own one. Competition in this sense is a win-win situation. Keep in mind that as you lower your prices you are lowering your profit margin. This is not a bad thing, it just means that you need to resell more domain names to make more money.
Warning: Be very leery of reseller programs that are not ICANN accredited. You want to make sure that you are working with a legitimate company and ICANN accreditation is a good indicator that you are okay.
If you are just looking to sell one name you may consider getting a domain name appraisal. If you have a name that you believe is in high demand or that you know someone else wants this can be useful. In this sense, domain names are like real estate or anythings else, they are worth what someone is willing to pay. Even if you don’t get an appraisal and want to sell you can park your domain at a company that allows you to customize the page that visitors see. You can then add a link or some information on the fact that the domain name is for sale.
