I think the correct solution to fighting housing speculation is increase property valuation to real world prices, eliminate extra taxes on vacant apartments, and drastically increase (to about 5% - 7% of valuation every year) the property taxes on everyone. At 7.2%, the doubling period is about ten years. This should cool down the market.
