people hoard houses. This is why you have landlords, this is why the value of a property is significantly improved if there's a house on it, if you can rent it to people. I like the idea of a different incentive structure: no taxes on the sale of a newly built housing, high property taxes on houses with an exemption for primary residence, and leave the existing property tax structure for business and fallow properties alone. This way you encourage new housing being built, encourage ownership and not renting out housing as a business or sitting on houses to flip them.
