You're putting the poor in an awfully tight position there. Between no tax deduction for a mortgage and paying the same property tax (what you call land value tax) for their trailer as the mansion next door, they're kind of getting screwed.

And what about old people that have owned their own house for decades? If the local economy goes up, increasing the land value tax, they either leave or go bankrupt. And the kicker is that their investment into their home is now worth a lot less.
