TY - JOUR AB - Defines a system as ultra‐stable, stable or catastrophic. Likens the property market to a chaotic system. Claims that there are no commonly available computer packages to predict the future realistically. Suggests the use of a dynamic simulation and modelling tool (specifically DYSMAP2, University of Salford). Gives application examples. Concludes that events affecting the property market often take managers by surprise because of a failure to understand the nature of systems.
