In my city, which for the last five years has been in the top ten in the country for year-over-year increases (as a percentage), at least 10, up to 15% property value increases, a proposal, "Missing Middle" was introduced, to help increase middle-density housing availability. A study was requisitioned by the city, and found that "worst case, the effect on property value would be to reduce the -increase- over the next ten years to be 7-9% year-over-year". Holy hell, you'd have thought they were executing people's grandmothers in the streets. All of a sudden what I assumed were just people's homes were their "investment in the future" with some hitherto unknown to me guaranteed access to double digit home value increases. People who lived on dead end streets that would not have been rezoned (access to transit and arterials was a consideration) screamed that there'd be "constant traffic through their neighborhood", etc.
