I personally don't mind the area because it's quite central.
However, I generally don't like units as investment vehicles because they can easily get duplicated so you end up with too many of them in 1 area.
I wouldn't base my purchase on the API/Residex predictions.
They are looking at past performance and seeing that an area hasn't gone up as per their expected pattern they expect it to catchup.
In my opinion many investors are confused and reluctant to buy because
all they see and hear is doom and gloom. Interest rates are up, rents can't cover the mortgage, there is talk of a recession etc etc
If interest rates continue to rise, IMHO forget the 10% capital gains.
Also, considering the current economic outlook, I would be happy with 5% CG
Unit prices have dropped in some areas and can be considered good value.
I would also look at performance from previous years.
Have you looked at the 2008 property guide?
Here is the link, there are 2 parts and they have put Homebush in the Western section.
