It can be for some people. Certainly for most people here - we tend to be a pretty darn content group with our purchase. But I think we do need to be cautious. We only know and can evaluate our own circumstances, and a lot of people look at these analysis to justify something that it is a struggle to afford. Then, at the first financial difficulty, the house of cards falls down around them. And "hey look, if I bought resale in 2009 how much money I'd make if I sold now in 2013" is GREAT justification, in the worst way, for such people.
