The CRM we use at UrbanX is REX.
It is one of the best CRMs available in Australia for a number of reasons. It is a completely cloud-based system and this is so important because real estate is a mobile business. As an agent, you need to be able to access all your information when you are out on the road and be able to update information continuously.
REX like all of your other software and subscriptions, is covered by UrbanX.
