I think Vermont & Wartirna are already up (but not as high as Glen Waverley & Wheelers Hill)..
So I think, Mulgrave & Rowville are the one..
Just my 2 cents.. ;)
I will choose this option. If you can afford Malvern East, it would be better.
These areas are well proven, in terms of high capital growth.
Just my 2 cents.
