What about option #4 - Redirect your existing domain to the old domain? I bought an old domain that is 100% relevant to my current domain but currently has with very little content. It did have more content fours years ago. The old domain is 13 years old, pr=3, while my current is 7 months old pr=1 and a decent amount of content. The old domain I purchased was not expired though and I do not know if this makes a difference. What are the pros and cons of option #4? Am I correct to think that option #1 would result in no benefit from the old domain's age value and if so why is it not listed as a con, a MAJOR one. Its hard to believe that a 301 using option 1 would give my existing domain 13 years credit but I'll take it if it does.
But unless the domain name you want is undesirable to anyone else (e.g., it does not include real words or have a high search volume for the words), the odds are not in your favor. With over 210 million domain names registered and an active, worldwide domain name investing community, it is highly likely that someone else will also find interest in the domain name you are watching. As such, skip to Step 4.

DomCop has a great offer that all of you buying expired domains should consider. For the price of a couple domain names, you can use DomCop for a month, snag some excellent domain names, which would otherwise cost you thousands of dollars. If you're considering expired domain software and don't have the knowledge to program your own crawler, I'd lean towards DomCop.

That’s it for deleted domains which you can just pick up by heading over to your favorite registrar and registering it right away as long as it says, free and green here. If it says registered it’s obviously taken. This is obviously a cheap way to get some great links because let’s say, you know, this site we saw is not bad. It doesn’t have page rank, but that could be just because there was no content on the site. If it has a solid link profile, you can be sure that the page rank will come back and you can pick it up for about $10.
If you *really* want to be sure the auction partner is NameJet (because it’s a name you cannot afford to lose in the drop), you can email the technical support team at SRSPLUS and ask them if they follow the same expiration/auction procedures as Network Solutions. Be specific and ask, “Will the domain name, (fill in), expire and be available for auction on NameJet.com as the process is listed at https://www.domainsherpa.com/how-to-grab-an-expiring-domain-name/?”
So, what to do? Simply, you must use someones other hard work and thinking. People have already contemplated all possible variations, synonyms, they know how domain names are valued, know about keywords, type-in traffic etc. Every day tens of thousands domains names are expiring. Every single day. That is hell of a lot expired domains to pick from. The reasons why people "let" domains expire are various. Could be somethins as banal as forgeting to renew, could be as serious as physical death. Many let domains expire because they don't need them any more. But that is not your bussiness to think about.
Why does this matter? What's the big deal? Well, unfortunately, the vast majority of domains registered are eventually abandoned. For some reason or another, people just fail to re-register or renew their domain name and that domain name drops or becomes available to the public. Of course, the obvious reason is that these people simply did not make money off the website that they put up with that domain. Other bloggers and website owners simply don't have the time, so they just gave up on their online projects. Whatever the case may be, by simply registering these expired domains, you can resurrect the value they bring to the table. With the four situations that I outlined above, you can benefit from those situations by simply registering a drop domain.
As mentioned earlier, finding such expired domains can prove to be a daunting task especially if you don’t have a tool to make that process a walk in the park for you. Instead of spending your time searching for tools that you are not even sure will help you find expired domain names with lots of traffic and backlinks, how about you try a game-changing tool integrated into Webfire 3.0 software called Expired Domain Finder and make your expired domain search a lot easier?
The first is the link profile I and actually took this example carbondsystems.com because it looked like a pretty good choice. It’s from 2003. It has some links, some age and it’s in DMAS and looked at the link profile in DMAS. So, you just copy and paste the domain,  the home page it to here, click on the search links button and this will show you all the links to that site.
I’m ready to purchase domain hunter gatherer after seeing your video but I’m a little scared to spend money because all I need is information for South Africa and the Domains that expire for .co.za if you can do a quick check (not a long as the video ) on the features it has for .co.za and let me know id show my appreciation by purchasing immediately as this is my only concern.
I want to purchase a domain name that is to expire very soon. After looking it up on Whois, the owner is revealed to be 1 and 1, which doesn’t have a designated auction house based on your chart above. How should I go about trying to buy this? Because I don’t know if it will go to auction, and if it does, which auction house I should look at. It is set to expire soon: 2015-09-21
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.

Once a domain expires, the registrar will allow around 30 days for the original owner to renew it. This period depends on the registrar and can range from 2 weeks to a whole year. Once this period is over, the domain enters the "Pending Delete" status, during which it cannot be renewed, purchased or modified in any way. Once the Pending delete status is over, the domain is dropped back into the available pool, and can now be purchased by anyone.
