Its not to say keeping your money in a savings account isn't a sound decision... I would recommend to retires who are thinking of investing to consider such an option given their risk is magnified should they loose any part of their investment.
It is for most a means to an end. I do not put money in a deposit thinking that is where it is going to stay forever and start mapping my retirement out using a bank deposit as the way to get there. However it is a sure way of saving for the house you want with no risk.
The way ther transfer of ownership is taxed in this country I am not so sure the property laddeer is as easy to ascend as it was once. I have saved and the goal is to buy the house I want to stay in for the next 15 to 20 years and putting this money at risk in shares or more risky investments does not make sense when all I am really after is preserving the capital and somewhere to store it while it grows to a size that allows the buying of a house or whatever it is you are saving for.
