If the domain name is not with any auction house partner (I think that’s what you’re saying), then you can use a drop catch service anytime: https://www.domainsherpa.com/domain-name-backorder-services/ They do not make your order public information as NameJet and others do by sharing how many bids are placed on a domain name and thereby driving interest.
Finally, we’ll look at a bit of a different animal in the expired domains world and that’s pending delete. To do that just click on the pending delete button which is right next to the Go Daddy Auction’s button. What this does is it shows you domains that aren’t quite deleted yet. So, they’re right before they get into this deleted category in expired domains. They’re going to be deleted, so they haven’t been renewed by whoever registered them, so they’re going to get dropped.

The way this list is implemented means I can't update prices, nor removed sold domains automatically and sedo doesn't provide me with the tools I need to implement it properly. Unfortunately some users keep contacting me to update their domain prices or remove their domains and I can't keep doing that manually. So I've decided to disable the list for now.

Finding good aged high DA domains with natural links for SEO and filtering them through our expired domain tools is really easy. Contact us with your SEO or PBN needs to receive an offer. If you need domains for a private blog network, 301 redirects or other SEO strategies, then contact us!. Our pool is huge but so many domains are being bought that it’s diminishing at a fast rate.
Contains, Starts, Ends You can use the search bar to search for domains that contain particular keywords you are seeking, e.g. a search for "car" will yield results for all expired domain names that contain the term "car". You can also use the search tool to find domains that begin, or end with the search term too, with the drop down box next to the search form.
Finally, if you were to manually check for drop domains, you have to jump through many hoops. It's a very labor intensive and often confusing process. When you see that a domain name is available, you shouldn’t just stop there. You should also pay attention to how many backlinks it had, how niche-specific the domain is, what kind of websites link to it, did it get signals from social media, and other indicators of quality. If you were to try to look for drop domains manually, it can be a very, very intimidating process. Thankfully, there is an easier solution.
Answer: Many auction sites will allow you to backorder the domain name for free. Follow the process above to find the domain name registrar and auction partner site. Then sign up for an account at the auction partner site and enter a backorder. But remember, the domain name may transfer to another registrar at some point so refer to Step 1 above periodically.
There is a common misconception that domains expire on their expiration date. If a domain registration is not renewed by its expiration date, the domain simply goes into "expired" status, which means all services are shut off. Typically, we provide a 35-day grace period during which the current holder can still renew it for the standard renewal fee. For more information please review our domain deletion policy.

At the end of the day, this article is geared to startups, business entrepreneurs, webmasters and marketing professionals who need to understand the process, and I guestimate that the process listed in the article above accounts for 99%+ of all expired domain names. All of your points are valid and appreciated, but if someone is interested in buying a good, brandable domain name for their business, they should follow the instructions above to have the best chance of grabbing it.
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.  
The database also gives us the chance to analyse Whois, IP, NS, MX records and website content of every domain and to offer unique investigation and brand monitoring services for which websites like Whois.Domaintools.com charge a lot of money. With the tools we have developed we can offer Reverse IP, Whois investigation and B2B research in bulk at a world class quality/price ratio.

That’s awesome. For someone that’s willing to “dial for dollars”, I bet there would be a percentage that would convert. It’s a funnel, and the more you put in the top, the more you’ll get out the bottom. 66% success rate sounds high, but I have no data…one would have to try it and see. If anyone is interested, I’d love to interview you after you’ve made the calls and gathered the data!
[1] On April 11, 2016, SnapNames (owned by Web.com) and NameJet (partnership between Web.com and Rightside) combined resources on pending delete/dropping domains to better compete with other drop catching services. Going forward, backorders placed on either platform for pending delete names will go into a common backorder pool and will be fulfilled either by NameJet or SnapNames depending on which platform the backorder was placed. Pending delete names that have multiple backorders will be placed in a common private auction accessible to bidders from both platforms to participate in the live auction. Minimum bid increments and proxy bidding rules for NameJet will be modified to match those of SnapNames. Registrar expiry, and direct lister inventory will not be affected by this integration.

If your domain name was in fact stolen from you, please go file a police report as soon as possible. If, instead, you allowed your domain name to expire through carelessness or ignorance, then you’ve learned a valuable lesson: domains have value. I’m not saying this to be a jerk, I’m saying this because words matter and saying something was “stolen” when in fact it was allowed to expire is not truth. I’m happy to share my knowledge as clearly as possible for others to benefit from, and all I ask is that others do the same.
Some people might want to skip that because they think that they've already been crawled, which is a possibility and you can apply a manual exclusion to any results you think are going to be returned on Google for your search query. So things like YouTube, you don't want to crawl, then you can add them in there and it will ignore them if they returned in the search results. Okay, so that's yeah! That's pretty much the search setting query settings here. So your search terms go here. You can have as many as you like just enter them in their line separated.

Some jerk stole my .com domain name after I had owned it for 10 years and accidentally let it expire, and he’s trying to extort lots of money from me for its return. On the site where it says who owns it, it says “Domain Status: clientTransferProhibited”. What does that mean? The domain expires on September 26. He’ll probably automatically renew it, like he has for the past couple of years. But in case it becomes available, I want to grab it. I’m the only person in the world with my name, and I posted at a blog for 10 years with that domain name. So I’m really upset I don’t have my own name anymore.
We just need to take the Archive.org url and plug it into the Dom Recovery software and again, if you just hit recover, paste in the snapshot, click next, next, finish, and I’m going to let this one run in real time for you so you can see just how quick it is, and right now it is downloading the initial page, and now it’s downloading all of the other pages.
We do not only have Expired Domains, but you can also find lists of Deleted Domains for a lot of TLDs. Deleted Domains or Dropped Domains are available for registration and can be picked up for just the normal regfee at your preferred domain registrar! All Domains have the typical SEO relevant data, like Number of Backlinks, Archive.org Birth Date and a lot more.
