I actually think it’s healthy to see these posts occasionally.
(Just maybe not as often as they happen). It’s a good idea to review current conditions every 3-6 months, re-think the logic and re-do the math. If a housing bull assumed that prices rise 12% per year and get it stuck in their head, they may be in trouble now. Conversely, if a housing bear assumes that prices will drop 40% from the peak and get that stuck in their head, they might miss the fact that by 2010 inflation will have already eaten up 15-20% and the 20% nominal price drop is the bottom. (the preceding numbers were for purposes of illustration and not an actual prediction… well, unless it actually happens that way).
Knowledge comes from questioning your assumptions.
