Interesting scheme the NRAS, was only talking about it the other day.  Which real estate agent are you going through - we've had a few, none were spectacularly awesome....

Mt Lousia is prob not a bad area for that, personally i would not choose to live there (i don't like the north side of town as travel times are a bit painful due to 90% of the population thinking the northside is awesome, and subsequently there is a lot more traffic), but plenty of people love it.  Plus a new Bunnings and shopping centres being built there now.
