To give you another example, within my city there are 5 high schools and their rankings are vastly different. Students can only go the high school within their district of the city. Thus the housing prices are vastly different between the districts by 2x in some cases. Note that all the schools get the same funding. It is just that the parents wanting high achievement for their students put them in the better performing high school making the imbalance even worse and and the same time causing a housing imbalance.
