Taxation shouldn't be used as a tool to modify behavior. That's actually the exact opposite of good tax policy. Taxes should be broad based, with few exemptions, to raise the needed revenue while minimizing side effects.

The distortions in housing markets are often partially caused by tax policy, and those areas should be addressed (tax deductions for mortgage interest for example). Other than that, it's best to actually deal with the root problem: outdated zoning laws.

Taxation is a great tool for changing behaviour in many places.
