I’d add a bit to the wait and see crowd – particularly if you don’t have kids yet and may still elect (need) to move somewhere else eventually.
None of us “know” where prices are headed and its not entirely impossible that we pessimists are overstating the case… maybe. But, its not like a few years ago when every month might have cost you 1% or more. Wait – if you miss the “bottom” its not like you’ll be completely out of the market. On the other hand, if you buy on the way down you’re largely screwed.
