Moshe Junger indicates that a correct administration of properties or real estate complexes involves the management of several competencies that allow the delivery of an excellent and comprehensive service. In countries like the United States, for example, the administration of real estate is in charge of large real estate companies that are involved in all phases of the business, from the construction of the property, its delivery and subsequent administration. The reason is that it is a market of large proportions and that it delivers high returns. Therefore, its logistics structure must respond to the obligations and requirements that the real estate administration acquires over time. That is why the practice of managing a property implies efficient management, which controls all variables, whether direct or indirect, that are related to the commercial profile of the property and not only receive the rent on a monthly basis.
