Inflation reduces the effective cost of homeownership and raises the tax subsidy to owner occupation. This paper presents an asset-market model of the housing market and estimates how changes in the expected inflation rate affect the real price of houses and the equilibrium size of the housing capital stock. Simulation results suggest that the accelerating inflation of the 1970s, which substantially reduced homeowners' user costs, could have accounted for as much as a 30 percent increase in real house prices. Persistent high inflation rates could lead ultimately to a sizable increase in the stock of owner-occupied housing.
