Let’s play this out with a real example. Say you’re familiar with the real estate market in Tempe, Ariz., and you have the opportunity to purchase tempeapartments.com for $200. This might be a good deal. Tempe has a lot of rental property; it’s  a competitive market; and there’s ample turnover in the apartment space because the city is home to a major university. Ask yourself:
1) pending delete auctions.  These are domains that were not renewed and are going through a pretty complicated drop process.  You can backorder these names at the auction venues and then each attempts to "catch" the dropping domain.  If one is successful you win the domain at $59 if you're the only one to backorder the name.  If more than one person backordered the domain a 3 day private auction is held.  Once the domain goes through the drop process, the back links have pretty much zero SEO benifit to the new domain owner.
Your domain name registrar may provide you with a free one-page Website tool, which you can use to create a “this domain is for sale” landing page. Alternatively, you can create a single page (perhaps a hidden page hanging off one of your existing websites) that indicates that your domain names are for sale. You can then forward all of your domain names that are for sale to that one page.
To find popular phrases I opened up the Google Keyword Planner. This free tool by Google, allows you to find out how often a word or phrase is searched in Google. A phrase like “Yoga Mat’ has on average, about 10K – 100k monthly searches. That’s A LOT. However a more niche phrase like “Good Yoga Mats” only has 100 – 1K monthly searches. These seem similar, but I wanted to focus on the exact popular phrase that people are searching for.
Your system is broken, You took my lising money on an open domain http://www.australianfintech.com.au and then stuffed me around something cronic and no response from your supoport team either. I have spoken to Tony who is one of the main people there at a function and I will move heaven and earth to find his number and give him a piece of my mind!! I have 60+ domains to sell but it seems you do not want the business! BAD MOVE not accomodating clients!
Apart from pending delete and auction domains, you can use our domains crawler that lets you scrape websites in bulk to find domains that are available to be registered and have amazing backlinks. Your personal crawlers run on our servers and are entirely web based. You do not need to install any software or have a VPS or proxies in order to do use them.
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.

For the following TLDs you can now find a expired/deleted domain list. .gi, .gl, .gy, .hn, .ht, .ky, .mu, .om, .pf, .qa, .rw, .sb, .sm, .sn, .st, .sx, .tc, .tl, .ug, .uy They also show up in the Deleted Domains (last 7 days) list and in the Domain Name Search, however they are not in the pending delete list! I do not have a working droplist for them yet, so that is why they are not released in the pending delete list yet.
Where do I start? So I heard about bitcoin and I know it’s all the craze nowadays. Let’s start from there. I’ll hop on Google Trends and type in “bitcoin”. Google Trends basically tracks the popularity of search queries over time, it’s often a goldmine for discovering currently exploding or soon-to-explode topics/terms..etc. So here’s what it looks like:
