Hi Roam I have always managed my properties myself and do the majority of the maintenance and improvements myself. All the forms and regulations are generally online here in sa I can find all the forms on the following site: http://www.cbs.sa.gov.au/rentingletting/
If you are going to do it yourself though I think you have to have the right temperament and not be the type of person that is stressed out at every little thing.
