What&#x27;s wrong with #3?  Maybe it wouldn&#x27;t have been popular 10 years ago, but after seeing the disastrous effects of a housing bubble, I for one would be perfectly happy to see property speculation taxed heavily.  For instance, I think a simple solution would be to eliminate property taxes altogether for primary residences, but levy significant property taxes on investment properties and second&#x2F;third homes.  You&#x27;d have to design this bit well, though, because you don&#x27;t want to kill the rental market: a lot of people aren&#x27;t in a position to buy their own home.  Perhaps a tax break for a first rental house, but jack up the rates if you own more than one rental house.
