These charts are not very useful without taking interest rates and inflation into account; in fact you could almost use them to discuss interest rates and inflation, they are so intimately tied to housing prices and income. If housing interest rates stay low or drop, prices will keep rising. Absent wage inflation that ratio will go up. If inflation flows through to wages as it seems to be in process of doing, the ratio will stabilize or drop.
