The Investment in Housing As a Forward Market Transaction: Implications for Tenure Choice and Portfolio Selection

A model of tenure choice is presented which treats the benefits and costs of homeownership from a theory of finance perspective. The incremental benefits from homeownership over renting housing services are from two sources: protection against rental price risk (a forward transaction in the housing market) and from a possible capital gain from the eventual sale of a house (substitutes for portfolio investment). The cost of these benefits is higher initial outlay on housing, which reduces the funds available for portfolio investments. The comparative statics of this model is presented. It is shown that rental risk and portfolio risk add to the value of homeownership. Since homeownership is a partial substitute for portfolio investment, it is shown that the lower the covariance between portfolio returns and future home prices the more valuable is homeownership. In the presence of differential borrowing opportunities it is shown that the leverage available to housing significantly increases the value of homeownership.
