Abstract : Egyptian government has particularly focused on real estate development during the past five years to support the economy by selling lands in new cities. However, the sector is unstable due to several ineffective policies, regulations, and procedures. Noticeably, achieving sustainable development in new cities often faces challenges regarding land provision and effective governance. Moreover, the processes to regulate and control the land provision process are inefficient and ineffectual. Many researchers associate the existing ineffective land provision policies in Egyptian new towns with the absence of real estate market monitoring, capturing the accelerating demand for land and the rapid change in land uses .The importance of real estate monitoring is being raised due to the lack of a clear strategy for the governance of the real estate sector in new cities, accompanied with no clear mechanisms to manage supply and demand and the sustainability of the land provision process .Thus, purpose of this research is to investigate how a proposed Smart Real-Estate Observatory (SREO) might help in addressing these challenges, particularly highlighting its role in addressing the drawbacks and consequences resulting from the absence of real estate monitoring in new cities, in addition to the absence of governing frameworks for a sustainable development of the real estate market. Globally, there are many concerns regarding the use and employment of smart and systematic technologies to support decision-making via models that monitors, analyzes, and controls real estate data, adopt methodologies based on digital indicators, and implement technologies such as Blockchain technology and IOT. The paper, therefore, argues that there is an urgent need to move towards the governance of land demand, as well as studying the factors affecting supply and demand through the establishment of a (SREO) that helps decision-makers to optimally utilize land uses, and induces proper governance of the real estate market in new cities in Egypt.
