It is very possible that the owner has a recurring payment in place, or that the owner renews after it expires. Because GoDaddy gives a redemption period like all registrar, many domain name investors will actually allow their domains to go through auction to see what the “market value” is of a domain name and THEN renew it. It sucks if you’re the buyer thinking you won the auction. It happens often, unfortunately.
Simple question: say I get the URL I want via auction for however umpteen hundreds of dollars, what about the renewal prices? Am I at the mercy of the auction house every year I want to renew it? Is it as simple as paying 10 or 15 bucks a year like with GoDaddy with a URL I got not through an Auction? I’m willing to pay for the desired URL up front but I don’t know what that entails down the pike.

Great information! I’m actually looking to transfer one of my websites to other domain and I wasn’t so sure which should I choose it to make the best choice. I had no idea until now that you can use an expired domain. But what are the costs of such domains? But the expired domain aren’t very expensive? Due to the fact that they belonged to websites with great daily traffic? What is the price range of an expired domain?
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.

When a domain name that was previously registered expires, it goes through a grace period that allows the previous registrant one last chance to reclaim their domain before it becomes available to new buyers. If the previous registrant still has not renewed their domain after the 77 day deletion process, the domain name will officially expire and enter the Aftermarket.

I've seen some people comment about losing the link value of domains that have expired and picked up, but what about non-expired domains?  Let's say a competitor is going out of business and they still have a year or two left, and we buy their domain and site.  Is there a risk changing registrant info and registrars, even if I keep their site up and mostly the same as before?  I was under the impression that I'd want to keep it under their name so as not to hit the uber-reset button on the domain's inbound link value.
Domain name market is heavily oversatured these days. There are more than 80 milion domains registered in total. Finding a right domain name is sometimes nearly impossible task, especially if you are not willing to pay extra cash to buy a domain that is already grabed and now for sale. If you have already tried to type in domain names for availability you probably had zero success, especially if you have searched for more generic words and keyphrases. The author of this program remembers he searched virtually for weeks to find some more or less usable names that he could use, and that was years ago. Since then, finding a good domain have gotten harder. Much harder.
The third option is the one that's the most time consuming but also has its benefits. It's like having a successful restaurant and buying another restaurant and operating them simultaneously. They're not the exact same restaurant, but both are popular in their own right and make you money. The same goes for Option #3. You could update the content on the old domain and sell the same products that you're selling on your current site. If you can get both sites to rank alongside each other in the SERPs, you're increasing your conversion chances and sales potential.
