This is a question which can almost cause good friends to come to blows. It seems that investing in residential property is such an emotional issue for some people. Well to add fuel to the fire I found the results of a study published last year found that investing in shares produced a better after tax return than investing in property.
The report was commissioned by the Australian Stock Exchange and prepared by Russell investments. It investigated the returns of a number of asset classes over the past 10 and 20 years taking into account the impact of investment costs, tax and borrowing on the on the final performance figures.
The headline result (certainly from the ASX's point of view) was that Australian shares outperformed all other asset classes on an after tax basis over 20 years for investors on both the lowest and highest marginal tax rates.
