I have recently found that towns in the mid north of SA are very interesting. I have particularly looked at Peterborough. I have spoken at length with a real estate agent as well as the locals there and discussed the immense shortage of rental properties. People there are prepared to pay a slightly inflated price for rent. CG is also still going well. Cost of houses are alos good, you are quite easily able to find a decent 3br home in a good area for around $75,000 – $85,000, even less if you are a bit of a handyman and wish to renovate a bit.
Might be worth checking out. To me it sounds promising.
