Abstract (EN)In this paper we examine the applicability of arbitrage theory to real estate. Arbitrage theory has been applied to the valuation of mortgages using partial differential equations, however the implicit assumptions made are problematic when applied to real estate. The latter is a very complex financial asset, and for instance, for the case of default options, one could produce very large errors (even up to 100%) by applying - unwisely - conventional arbitrage theory techniques. The consequences of real estate appraisal are in this paper studied in particular. Because one has encountered similar problems in real options theory as in real estate, the tools developed in that field could probably well adapt to real estate; we provide here an example. Finally the possibility of pricing contingent claims written on properties is discussed.
