No one knows what will happen, there's so much money being pumped into the system and market intervention.
The market never crashed before because interest rates have been kept near zero. The price of houses is dictated by how much people can borrow. If people can borrow more because of low rates they won't fall.
Could rise by 10%, could fall by 10%. Will know later in the year if the stamp duty ends and things return to some kind of normal.
Long term they'll need to return to some kind of relation to wages, but who knows what form that will take.
If there isn't some correction it doesn't bode well for social cohesion with the young that keep getting sacrificed.
