Land Value Tax: Make it financially unfeasible to speculate, to withhold units from the market, and to withhold unused land from the market. Let prices freely fluctuate with the market. Increases in rent derived from externalities (i.e. Amazon HQ2 setting up shop nearby or a new subway station) go back into public coffers, while increases in rent derived from landlord actions (i.e. renovations, building bigger, better units that command higher prices) go directly into their pockets.
