This paper evaluates how economic theory deals with analyses of current real estate dynamics and urban residential structure. It shows the fundamental axioms of neoclassical spatial synthesis and their explanations in terms of equilibrium, and highlights ambiguous and unsatisfactory, but elegant, solutions to urban spatial economic structure and dynamics. It presents the critical heterodox approach to the fundamental axioms and the hypothesis of spatial equilibrium, and shows the main aspects of the central heterodox contribution to residential real estate dynamics.
