Id kick the speculative investors out of housing. No more leveraging billion dollar hedge fund resources to outbid home buyers driving the price of housing to the moon. No more nimby regulations that prohibit building above a certain number of stories, building certain types of homes or the number of unrelated people living in a house. The only regulations left on the books would directly tackle legitimate safety concerns and thats it. Id make it as easy as possible to upgrade or build new housing while enforcing the regulations necessary for housing to be safe to live in. Id encourage the formation of cooperative housing i.e the people living in a complex are part owners and so the management of that building is incentivized not to screw them over. Id dump money into public housing and bolster the occupants’ ability to take care of themselves with job training, education and support they need to dig their way out of poverty.
