Why can't house prices be out of tune with salaries
The three basic needs are food, clothing, and shelter. Housing falls into the third category. Because it is "basic," housing takes up a large part of one's disposable income. The rule of thumb is that you shouldn't spend more than 25% of your income on rent or mortgages. And that is income BEFORE taxes. Anything much more than that takes up too much of one's budget. You simply CAN'T double housing's share of the budget from 25% to 50%. Whereas, it's easy to go from 1% to 2% for say, a cellphone upgrade. In the long run, housing prices are constrained by the size of people's housing budgets, which in turn are tied to incomes. Nowadays, that includes FOREIGN buyers. So there may be a case where west coast housing prices are driven up by Asian buyers, or Florida housing by buyers from Latin America, driving Americans out of local markets.
