I have an interesting twist on how I have done it in the past. I will buy a domain and use it as a development domain for blog posts and things of that nature. Then over time it will gain DA and PR. Then I will sell it off and buy another development domain and start the process over. Not quite the process you mentioned, but it works. People will link to the development site to show things off as well  sometimes, so that helps.
Let’s just say for example we wanted this site, crystalgiftsworld.com. It looked good based on our analysis and we’d head over to Snap Names, Nameja is another one and what these service do is they have special technology on their site that allows them to try  to register a domain on your behalf over and over again. Okay? If you tried to do that your IP would get banned, but they have some system where they know how to do it just enough to get the domain, but not enough to get blacklisted.

This is similar to house flipping, where a home is purchased and fixed up in order to sell for a quick profit. Unlike house flipping, however, there is essentially nothing to be done with the domain name in order to increase its value. Therefore, the key to a successful domain flip is being in the right place at the right time in order to acquire a valuable domain name before it is given a premium price.

There are currently two main types of domain speculators: those that buy domains, build sites around them, and then flip the domain and accompanying website, and then there are those that buy and sell domain names without web sites attached. While both can be very lucrative businesses, the second type is much easier for novices to learn, and as such, shall be the topic of discussion for this article. 
When the domain drops, the minute it drops, literally, they will try to get it and if you can get it, it’s yours. So, that’s it for expired domains. You can see it’s a little bit complicated and it takes some leg work, but if you’re interested in building a publisher network or a private blog network, this is a great way to find sites that have a great link profile without you having to actually build any links. So, that’s it for this video. I’ll see you in the next one.
The IP popularity and domain popularity each play a part in the overall quality evaluation. If you come across an expired domain with a high link popularity (i.e. a large number of backlinks), but then poor values when it comes to IP and domain popularity, you can assume that these links were obtained in an artificial way. Domains like these will have already caught the search engines’ attention. Perhaps this is the reason why the domain was abandoned. Users that want to start a serious online project should steer clear of these domains.

Perspective buyers are able to directly contact domain holders in cases where the desired domain is no longer available. Most registries openly publish the names and contact data of domain holders. Once this information is gained, buyers can get in touch with domain holders and make an offer for the name. Sales are also known to occur in instances where the original domain owner had no prior commercial ambitions

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. 
I'm not against making money in any way, but $400 doesn't really seem worth the effort and coffee expense invested (I like the good stuff). This is a very basic example used to put the costs in perspective. Most SEO providers charge more than $50 per hour, and you get what you pay for. The above example of a final labor estimate is probably much higher, or if the domain is already ranking high and the owner wants to sell, so is the initial purchase price. Since this is often repeated many times over for multiple domains, it could get time consuming, and expensive.
Something wise my father once told me "Something is only worth how much someone is willing to pay for it." This small seemingly unimportant statement has guided me in many selling and purchasing decisions in my life. Sometimes, it makes the reality all too apparent. So, is buying a domain with the intention of selling it a good idea? Let's break down the details, and talk to some people that actively pursue this method. Yeah, we know a guy.

Hi I totally agree with you Domaineer42. My partner and I are web developers and are seeing a lot of ‘hype’ selling and not enough ‘real value’ selling based on actual search engine criteria. Recently brokers have knocked back selling domains with great potential value based on some pie-in-the-sky logic, defying even Estibot values we’re told to use. The domains were not our best but with four figure value, according to Estibot, I thought it was a great start as a newbie to domaining. In an industry which should flourish, some of these domain ‘fashionistas’ are making rods for their own backs by devaluing domains that have REAL potential value based on customer search. I don’t understand what is going on, but I have decided to opt out for awhile. We have quite a few domains in our repository, with data backed search criteria, trending upwards. Will bring them out of the closet when the industry is ready to get real.
Check DA/PA: The “Domain Authority” and “Page Authority” metrics gained significant popularity over the last few years. They seem to correlate well with a domain’s ability to rank in the search engines and hence, a domain having a high DA/PA will typically have a higher value. This is not to say domains with low DA/PA can’t sell for a lot of money because, at the end of the day, it’s just one factor. However, it’s good to take a look at these as they may tip the scale in favor of or against some buying decisions.
Karn Jajoo heads the premium names program for Radix’s domain extensions: .WEBSITE, .PRESS, .HOST, .SPACE, .SITE, .TECH, .ONLINE, .STORE & .FUN. Radix has made more than $1.75 million in premium domains revenue in 2017 thus far, including the biggest nTLD sale of all times — casino.online, and the sale of business.site to Google for it’s free website builder, Google My Business. Karn considers himself a new gTLD evangelist and has had articles published in The Next Web, Website Magazine, & CMO.com.
Please keep in mind that domain flipping isn’t child’s play. As much as you may want, it isn’t easy to buy and sell domain names for huge profits without putting in a good amount of time and effort. Although there’s nothing wrong in aspiring for at least one big deal per month, be aware that sometimes it takes months and months to sell just a single domain name.

Now, a lot of times these great domains that have pending delete will get snapped up in a flash. Okay? You want to use the same system that’s 500,000 domains so you can always sort them by whatever you want to do to make sure you’re only looking at quality domains and look at the link profile the same way. Once you find one that you like, you can’t just sit on your computer at Go Daddy and wait for it drop on 6/14 and expect to get it because there’s going to be a lot of other people gunning for that domain. You actually have to use a service like Snap Name.
As mentioned earlier, knowing the potential value of a domain name is an invaluable skill. By adhering to basic guidelines such as those I listed above and through some of your own research, you’ll be able to pick names that offer you a higher chance of flipping them more easily. Remember, a net profit of $100 is still a profit, you must start somewhere.
