It's a vicious cycle. Housing prices in a neighborhood are high in no small part because the schools are considered good (it's a very meaningful metric when people are looking to move to a new state or new part of a state). And the schools are good because housing prices are high and so is property tax. How do you fix that problem? Probably some complex analysis of financial metrics tied to the school, its students, the economic statuses of those students' families, and well...a bunch of other stuff.
