Thanks for the advice guys, The areas we are looking all look prime for capital growth,  They are further out from the CBD but not to far.  They all have either major infrastructure coming their way or border areas ear marked for Urban Development.  The plan is to buy a house on a decent sized block 600m2 + as most of the areas I am looking at have been rezoned to allow higher density   which I am assuming will help capital gains.  All the houses are also within walking distance to train lines and close t major shopping centre's. 

Is there anything else i should look out for that will be important for when it becomes a rental.  I know the capital gains  have no influence on the rental side of things but is a nice bonus.

I think I will buy now, having watched the market for the last 18 months I've seen prices in Brisbane continue to rise until very recent small price drops.  Most of the areas I am now looking at have not dropped in price but i have noticed properties on the market for up to 3 months.

I think my best bet though would be to seek professional advice, we already have an excllent mortgage broker however a financial advisor who has experience in proprty is probably a good idea. Is any one able to recommend on in Brisbane, specifically on the northside?

Thanks again for the help.  Heh I knew I'd been lurking these forums for a long time but until this post I hadn't realised its been 4 years lol.
