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.

However, Pool uses what some have called a “two-phase” auction system. This means that once you win your original backorder, Pool will then move you into the auction phase where you compete with other bidders for the domain. Pool doesn’t reveal how many bidders there are or what they’re bidding, so you have to offer the highest price you’re willing to if you want to get that dream domain.


Next, some of these expired domain names have ranked in high authority sites that are ranked or had ranked themselves. Besides, some of these domain names are worth a fortune. For example, domain names sell for about ten to twenty dollars each. However, those that are the most sought after can go for over $ 2500 a month because they have lots of traffic back links or rankings.The last advantage is that you don’t have to spend much to find expired domains.
Especially each and every Domain Name always renew after a year. While People make mistake sometimes or forget to renew their crucial domains. Therefore, these domains are available to purchase by others. Users spend years and lots of money in building and marketing their website. If they suddenly shut their business or don’t want to maintain their website anymore. As a result, these sites have considered Expired Domains. And you can pick up anyone. These domains may have high residual traffic, backlinks, and history. Hence, you can take advantage of these domains.
Here's an old post on search engine roundtable that claims google's policy is to discount previous backlink juice when a domain changes ownership.  I'm not convinced whether this is actually true or something Google says to discourage excessive domain buying / 301 redirecting for SEO benefit.  The comments above seem to give varying opinions on this matter. Would be great to get to the bottom of that one!
GoDaddy Auctions is a marketplace where GoDaddy lists domains that have expired and are in the renewal grace period. Apart from these GoDaddy also lists other domains, but the expiring auctions at GoDaddy are the most popular. Based on the percieved value of the domain, domainers and SEOs bid on these auctions. If the original owner does not renew the domain, the top bid wins the auction and gets the domain name.
So, what I like to do is also choose DMAS listed entry. No fake or no unsure page rank. Click the apply filter button and this will show us a much better group of websites, including a lot of high page rank websites. That’s one great thing about Go Daddy Auctions that you don’t have to guess about what the rank will be which is not the case with a lot of deleted domains which, because they were deindexed they didn’t have any content, they didn’t have any hosting, they don’t have any page rank. So, you have to make an estimation.
