Hi Sam,
Just a thought, but could it be that there are more 2 bedders up for rent because there are proportionally more 2 bedroom apartments in Hawthorn. I would think Hawthorn would have more 2 bedder apartments because it is more of a family area.
As for Hawthorn itself, solid profit growth and moderate rental yields but with good scope for appreciation in both.
What alot of people dont realise is that rental yield might be low in high cap growth areas, but in the long run, rental appreciation is greater and the rent yield will still be based on your original purchase price (or u can increase priginal PP by inflation if you want). Hence I am happy buying a low yield investment in a high growth area safe in the knowledge that in the long run, my rental income will be WAY better than a low growth area.
