>Property values keep increasing because demand is exceeding supply.

Not quite. Property values keep increasing because the monetary supply keeps increasing, one effect of which is that large property owners can corner markets by buying up properties and warehousing them until they see the prices they want to sell for. This appears as a lack of supply (not enough houses) when it's really a lack of market forces forcing sales (not enough houses on the market). The remedies to these two situations are very different.
