Condominium and Cooperative Housing: Transactional Efficiency, Tax Subsidies, and Tenure Choice

TWENTY-FIVE years ago, cooperative apartment buildings were uncommon in the United States, and condominiums were virtually nonexistent. Since then, however, both forms, and particularly condominiums, have spread rapidly through the real estate market. This article explores the factors responsible for this development. In the process, it also assesses the relative transactional efficiency of consumer ownership and investor ownership in multiunit housing. I argue that two factors appear principally responsible for the recent spread of cooperatives and condominiums. First is the large tax subsidy to owner-occupied housing that has existed since the Second World War and that has been particularly large during the past two decades. Second is innovation in the forms available for organizing ownership in multiunit dwellings. A variety of considerations suggest that the first of these factors has been more important than the second and that, in the absence of the tax subsidy, cooperatives and condominiums would occupy a much smaller share of the housing market than they do at present. In support of this analysis, this article offers the first sophisticated calculations of the magnitude of the pure tax subsidy to owner-occupied housing, as
