The laws for building new homes haven't changed much in a few decades. The houses being built are a result of equilibrium with profit and secured funding. Every single action you have proposed creates no new homes.
Your proposed change is to devalue all existing homes further, incentivizing people to not own and leave the state, while allowing the state to price people out of their existing assets by forcing an increase in higher property taxes every single year that is based upon the entire amount of the loan, rather than any equity they might have.
This is no less than state mandated stealing from who you perceive to be rich (homeowners), while creating no new homes; because homeowners aside from developers do not build homes.
Do you know what happened in San Fran areas where they created and enforced the rental boards? Property values dropped, rentals dropped, everyone with options didn't invest in the area, business left, no jobs available, police couldn't be funded, and people regularly get killed as crime increases.
Do you even know how much the price of real estate fluctuates over longer periods of time? Some years it increases, other years it stays the same or decreases. That additional property tax is based upon appraisals that don't happen regularly, and the percentage increases every single year.
For a regular home, it already increases each year by at least 7,000 dollars in property taxes. If you have a well paying job of say 50,0000, roughly 32,000 goes to food right now, more if you are not single; and if they got the funding for a house they wouldn't be able to pay property taxes in less than 3 years at existing rates, regardless of the equity they had since its about appraised asset value. Increasing that further and the economics say the asset class is no longer an investment but a negative cash-flow cost.
Honestly I don't get where you people seem to come up with these things being a good idea. Did you do any research before you actually proposed something to see if it was viable?
Or is this just mindless indoctrination speaking?
