Once you’ve settled on some domain name ideas, you can head over to a bulk domain search tool such as DynaDot’s to mass check all the names against different TLDs. When you’ve found one (or a few) good candidates, you can simply go ahead and register them for approximately $10 each. The next step would then be to market them. Then finally, it’s a waiting game.

There are many places and ways you can purchase domain names.  You can purchase unregistered ones through sites like GoDaddy.  There are forums where people will gladly try to sell you their domain name (usually though the domains being sold in forums are either crap or the asking price is so high it does not allow you any room to flip the domain).  And then there is my favorite way of obtaining domain names, through an online auction at Namejet.  Let’s first talk about Namejet and then we’ll talk about how I personally ring the register by flipping domains.
Then the number is an HRL so it’ll be quite a bit different then you’ll see an expired domains because domain pop service is not very good compared to HREFs. Usually this shows about 20 percent of the total lengths. This shows more like 80. Okay? As you can see it has actually 162 referring domains which is quite a lot better than we saw in expired domains.
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.
Content setup: If your domain has potential to attract good search engine traffic, you might want to set up some content to help facilitate that. If this helps your domain do better in the search engine rankings then it’s a big win regardless of whether you choose to flip the domain only or flip the domain with the content as a “website”. The SEO value will be helpful either way.

In the past, expired domains were used as part of black hat SEO in order to generate backlink sources quickly and easily, and this practice is still used somewhat today. Getting links in this way is not a recommendable practice. All relevant search engines work nowadays with highly complex ranking algorithms, which can no longer be outsmarted by these link networks.
Finally, you want to head over to domaintools.com. Then put the domain into here. What this will do is it’ll show you the history of the domain, because a lot of times these domains have been dropped like four or five times and a lot of people in SEO feel this way. I’m not sure about it. If a domain has been dropped several times, then Google does actually devalue the links pointing to that domain. So, as you can see I just changed registrars a few times and it hasn’t been dropped or else it’ll say one drops or two drops.

Here's a test I have in process.  I bought an old $5 closeout domain from Godaddy TDname expired auction.  I put a quick minisite up and linked to it with a crazy anchor text phrase.  The domain is ranking for that crazy term now.  It's gone through one pagerank update and I'm waiting for a second to come.  Then I'll redirect the domain to another minisite.  I suspect the second site won't rank for the anhor text, but we'll see.  

Dictionary Word/Pronounceable/Memorable/Brandable: A dictionary word domain name is very valuable. Of course, the more popular and widely used the word is, the better. For example, “marketing.com”, “cars.com” and “hotels.com” are 7-8 figure domain names. Even if a domain name isn’t a dictionary word, being pronounceable and/or memorable and/or brandable are all big pluses that add to its value.
