It's certainly true that retirement lifestyles can be funded by all savings and wealth and not just a pension, but this research is a salient reminder that the vast majority of home owners don't want their home to be part of that funding. 

Property as an investment can be looked at in a number of ways: your home can appreciate and so can help you to build capital but this can only be realised if you sell it. Property can also be bought to rent out, so providing income and potentially a return on capital if the property increases in value.

For a majority of people their home represents the single most significant part of their total wealth. So investing in property on top of that is something to be carefully considered as this imbalance in one particular asset class introduces more investment risk and a poorly diversified investment portfolio.

For those people who have significant pension savings and who are limited either to a maximum of £10,000 annual pension tax allowance, or nil if they have already reached their lifetime pension tax  allowance, then property investment may be an alternative they wish to consider.

But, it is not the only choice; there are other assets classes to consider such as deposits, gilts, bonds, stocks, funds and alternatives. Each, including property, have pros and cons: on their own merits; when looking at them as a replacement investment for a pension; and in their suitability to each individual's retirement plan in line with their own circumstances, needs and attitude to risk.  

For those looking to invest property in addition to their own home, it is vital to talk through this with a financial adviser to see if this really is the best way to use your capital and to understand the benefits and risks involved.
