Real estate Australia purchases may be more or less advisable specifically in regard to the particular area of this vast country which an individual or company happens to purchase or otherwise secure rights to use. That being said, observations on the real estate/ Australia market have noted that a so-called property bubble may be forming in this area of the world’s economy. Observers of real estate Australia value levels have based this prognostication on a comparison with the models of other comparable real estate markets in other countries. Real estate Australia market value was noted for a continual increase over a period of 60 years, over the course of the 20th century. More recently, 1997-2003 real estate Australia prices were noted for a particularly rapid period of improvement. The 2003-2010 period for real estate Australia market prices, by contrast, were noted for a comparable level of consistency and lack of change either in a positive or negative direction. The world body known as the International Monetary Fund, or IMF, issued a caution to real estate investors and other participants in this market for property which cautioned of an imminent collapse not just in real estate Australia prices but also in the market value of real estate in such other countries as the United Kingdom, the United States, and Ireland. A later 2008 IMF announcement was made particularly on real estate Australia value, finding value estimation to be inflated by one-fourth. Goldman Sachs announced in 2010 that real estate Australia prices were overvalued but not to the point of a bubble.
