The market-driven principles of the domain trade mean that a domain is only worth as much as the buyer is willing to pay. It is for this reason that criteria such as market potential and usability play such central roles in determining prices. Values can change immediatly and without any warning. The price of a domain that was once of little interest to anyone in years past can skyrocket once, for example, a newly founded company takes interest in that same name.
Buying and selling Domains is a tricky industry. You easily get addicted to it without really knowing what it's all about. Unfortunately I learnt a lot of the answers on here after losing 6k on useless domains. It is a constantly changing industry but the subject that keeps coming up is TRAFFIC. Organic type in Traffic. Those premium domains are long gone and you need to spend big bucks to acquire them on secondary markets such as Domain Auctions, Expired Domain Names, and Available Aftermarket Domain Names for Sale but if you keep up to date with future trends then you can spend less on hand registered names. You really need to think outside the box and spend a lot of your time reading industry leading blogs like business insider, network as much as you can and have a specific niche before jumping into other trends that you don't quite understand. There's so many ways of selling. Don't try and sell to other people who are trading domains aka domainers instead look for an enduser on Google by typing the name you own and if there's advertisers then you have yourself some leads or use tools such as Free Domain Appraisal and Domain Productivity Tools. A buyer can be convinced to buy if you have the numbers to prove how much that domain would be worth to them. Find out how much they spend on advertising per month then make comparisons with the number of direct type in traffic they get from your domain that you selling. If you can prove these numbers then it's easier to sell otherwise you better off holding on to it, maybe develop it the way Trump has developed his name until someone interested gets in touch. There's so many platforms where you can list the domain such as The world's leading domain marketplace , Park Domains - Afternic etc . Please NOTE  I am not promoting any of these services but I have used them before and have had some success. Probably should have signed up for their  affiliate programs but haven't had a chance before this question came up. There's so many other metrics involved  so research as much as you can, don't spend a day without reading about the subject and go in at least knowing what you are doing. My two cents.

One of the easiest ways to make money online is by buying something for a low price and selling it for a higher price.  It is even better when you don’t need to pickup or ship a product.  Today I’m going to talk about how to make money online by flipping domain names and how I personally have made tens of thousands of dollars in the past year doing this.
Domains that are indexed on Google and highly ranked are particularly attractive to traders. Other SEO aspects, such as backlink profiles or the search volume of the keywords in domain names, also play a significant role in calculating thevalue. Design can also positively affect the price of a domain. Short and succinct names that are easy to remember are especially advantageous. Endings are further factors that should be taken into account. Top-level domains (TLDs) such as .com or .org are by far the most sought-after endings.
Before you park any domain names, you must focus on finding hot keywords that buyers would be interested in. The best way to make sure you get a good return on your investment is to pick a domain name with acceptable traffic, somewhere around 10,000 searches a month. You can do this conveniently by using tools like Google Keyword Planner or Niche Finder Software.
Length: This is pretty self-explanatory. Generally the shorter the domain name, the more valuable it is. This difference in value decreases exponentially as the name gets longer, though. For instance, the difference in price between 3 and 4 letter domains are significant, while the price difference between a 7 and 8 letter domain would usually be much less significant.
