I am saying anything that is not sensible will have to come back to equilibrium eventually. In this case, the income to house prices ratio has been severely skewed in the last 20 years. So either the average income needs to go up drastically or the house prices need to fall to a level that is reasonable or both! Now this happens dramatically in the next of couple of years or really slowly for the next decade or so is debatable & I don't believe in making predictions.
