Stable or mildly stagnant prices are not a problem to people who don't have excess amount of debt through mortage/refinancing. However, there are lots of these people and for them this is going to be ugly. Housebuilders will suffer as well. Many of these people banked on those juicy 20% value increases and are now getting far less if anything. Their loans will eat them alive, especially now that feds are raising interest rates.
