I don't understand this plan. Won't you lose all the money you spent buying the houses and building the quadplexes?
I think that the plan isn't to make money, but to make real progress on solving housing availability.
Kind off, the potentially low marginal cost of everything housing construction related (due to AI and robotics) really creates a lot of space for creative business plans here.
The municipality can’t take away the land (most of the value here) and putting the house on top will be relatively cheap, given the low total labor costs.
It's simply pitting the most dysfunctional municipal and judicial systems against each other with the default outcome being people being housed.
