That doesn't make sense... Yes units have had their fair share of growth over the last 12 months*, however the prices being asked for units are practically the same if not more than houses in the same areas, if this was the case you would buy a house.
300k may get you an older style 80's brick -2 bed which would rent 300p/week at best ,which would be highly neg geared with body corps and 10% interest rates. Maybe the only upside is vacancy rates whichwill be very low, but who in brisbane can afford higher rents? which leaves you little room to increase, to improve cashflow
IMHO I think the outer suburbs still have alot of catch up to do in regards to capital growth, also yields are better helping with cashflow.
250-300k will get you an older style has, whilst still achieving similar if not better rents.**
*I assumed a long-term view, i.e. 30 to 40 years. I don't really care much what the last 12 months have been like.
**My focus is completely on capital growth, and again if you're talking about 30 to 40 years, rents don't matter much either.
So to me, I still think captial growth focused investors should look as close to a CBD as possible, regardless of the property type. Sorry if the original poster has a different strategy, I have just offered mine.
