I have been trying to understand what is being dispayed on the Home Open website. Am somewhat underwhelmed. About one third of the webpage is taken up by a map and there doesn't seem to be a way to remove (or reduce the size of) the map. The map has red dots on it with numbers. Don't understand that. Is that properties for sale, kilometres from ?, not sure. One property had a blue dot with 5d - what is that? Days till auction possibly. Is there a legend or guide to help understand, navigate, explain the website? Is there a way to find out the number of listings for a location - eg. properties for sale in Brisbane, or New South Wales? Does the website provide any option to access SOLD property prices?
