The interesting thing to watch for is the flipper sales. Which is to say if a significant chunk of the market in your area is actually being held by people who bought the house just to flip it, then when you get two or three months of flat to downward pressure on house prices they will all yell "Peak!" and run for the exits. Then you'll see a nice flurry of downward movement as these folks try to unwind their position before the market falls into a hole that loses them money. Pro tip, there aren't enough chairs and the music is no longer playing :-).
That could bring some welcome relief for home buyers who have struggled in the 'no contingency cash only' markets like parts of the Bay Area.
