Yes, so historically it has been a rule of thumb that this is a third of the disposable income. What a am considering is whether people are ready to move that to half? Two thirds? My own assumption is that people are willing to do this as long as they believe that the house will be a good investment. But houses can never be a long term good investment. It will always converge to inflation.
