I have remarked before about the way in which investment in regional real estate can provide good returns relative to the city alternative.
The Sydney Morning Herald had an interesting story, Country towns lead the way on rent increases. The following graphic shows increases in rentals for selected NSW LGAs for for houses for the June quarter 2011. The column that I was especially interested in was the one on the far right showing gross rental yields. You can see the range, with highest yields generally to be found in regional areas.
Equivalent figures for units can be found here.
