Maybe grandfather in existing property owners, but expire it when it sells. At some point the narrative has to flip to the Granny in her 1.5m home paying $1200/yr in taxes vs. the young family next door struggling with kids, student loans, and a $16k/yr property tax bill. Where's the fairness in that?
