CasRealestate is an integral division of the multifaceted Property Development Group of Companies — CasCorporation. CasRealestate is not the largest Property Management Company in Melbourne, and we don’t strive to be. So often we meet overloaded Property Managers with excessively sized property portfolios who simply do not have the time to care for a property as they would their own, nor are they devoted to providing an expertly guided investment plan to their clients. CasRealestate is different.
