I'm not as familiar with west although I did have a property in Toowong which did very well because of it's closeness to the university. Lots of older properties ripe for renovation but can be very expensive
Suburbs close to new infrastructure such as the Airport Link M7 shouldn't go wrong. You may have missed the boat for substantial gains but still opportunitues in suburbs such as Nundah, Kedron, Lutwyche, Chermside, Aspley and Geebung.
