And move where? Why have retired people (who are most likely on a fixed income and have paid off their home in some cases) to move from a home they've paid off to an apartment/living center with obscene monthly payments? Or introduce another ever rising tax on something they should have been able to age peacefully in without as much financial worry? That seems cruel. I'm no fan of boomers, but damn.
I feel like best plan here would be to impose steeper taxes on second-plus properties. You can have your primary residence, but every home after that accrues a higher and higher tax. Especially on LLCs.
