Also
PR doesn't always mean anything. I see people buying a
pr domain cheap and throwing a site up on it that isn't worth anything.
- Make sure they actually own the site (no stolen or copyrighted material)
- Always ask for proof of traffic & revenue and verify it
- try to stick with buying sites you know how to run or have some knowledge about
- try to stick with sites that are unique and not something that 1000 other people already have
- purchase sites that have a history not completely new
- do your homework before purchasing
- don't buy a site you don't have time for
