A collaborative real estate search is described. Overlay data including indications of properties for sale within a geographic area are provided to a first user device. The overlay data are capable of being overlaid on a map of the geographic area on a user interface. Selections of some of the properties for sale are received from the first user device and a list of those properties is stored within a folder associated with the first user. The system enables a second user device—associated with a second user who is associated with the first user—to access the list of the properties selected by the user. This includes enabling the second user device to cause information regarding the properties to be stored within the folder. The information is made available for display on a user interface of the first user device.
