Automation for real estate agencies usually starts with the inbox, because that is where the leads go to die. Idealista and Fotocasa drop enquiries into a shared address. Whoever sees one first replies, so the rest wait until somebody has a quiet moment.
The second drain is typing the same property three times. A listing gets loaded into the CRM, then into the portals, then into the website, and a price change means doing all three again.
Then come the owners. Each one wants to know what is happening with their property, so an agent rebuilds the same report by hand every month from four different screens.
