55% is one of the lowest home ownership rates in the country. If high levels of home ownership drive policies that prohibit new construction and drive up prices, how is it that places like Minnesota, with a home ownership rate in the mid-70s, are so cheap to live in?

But, that increase is capped at a percent per year, which practically speaking means taxes lag behind home values when they increase.
