Considering the "new normal" interest rates around the world and the direction things are going (down), I have doubts housing prices will decrease in any developed country for the upcoming 5 years.
Do you anticipate housing prices will weather such a recession which many predict is looming on the horizon? That would be a first.
The FED seems ready to drop rates at the first signs of economic bad news and consensus is that it will this year. Party will go on until inflation skyrockets, no idea when though but I doubt it's too soon. (not before elections)
