Just replace property tax with a land tax and most of your concerns will be handled. Any land upgrade (like buildings) should not affect the tax from owning a property.
Also I think that although rental cost may increase (but it's unlikely as individual rentals will be much more down to earth than those operated by a corporation that's driven only by quarterly earnings), the buying should be much more affordable.
