Is this just me?
Yesterday I received yet another notice that my backorder of a .com domain had failed. The domain had no links, no PR - it never previously existed as a website.
You are incorrectly assuming that only domains with inbound links and PR have value. Common generic and descriptive domains can have significant value. If you are going after these types of domains, there is going to be a great deal of competition from domain professionals.
Oftentimes, these top generic and descriptive domains get registered by drop catching services the instant they become available for registration. If there is more than 1 person who wants the domain, it will go to an auction and get awarded to the highest bidder. Top expired domains routinely sell for at least 4 or 5-figures at auction.
If you really want an expiring domain, you should backorder it with as many drop catchers as you can. Be prepared to bid serious money if you want to win. Good luck.
