That data backs up what I am saying though. The national average means nothing, even state averages means nothing if where you are looking for housing, the vacancies are either not high enough to facilitate moving people around or are in conditions or floor plans that do not fit your needs. Not every vacant unit of housing is equally fungible.

California having one of the lowest vacancy rates and one of the highest median housing rates means there potentially needs to be a much higher rate of vacant units to lower housing prices if they are as inversely related as you describe.
