It’s official – Australian homes are now the largest in the world – 6% bigger than the average US home,  and amazingly nearly three times larger than the average home in the UK.

Data released yesterday by Commsec shows that over the last 20 years, the average size of a home in Australia has increased by more than 30%.

The houses are emptier too, with the number of people in each home gradually declining over the last 100 years because of a trend towards smaller families.  This trend has only just started to change, with the number of people to a dwelling rising slightly last year – the first time it has done so in over a century.

However, with the increase in house sizes, there appears to be a corresponding increase  in rental costs.  A report from BIS Shrapnel has  also forecast that rents are expected to spiral – with increased rents of 5% a year in most capital cities over the next few years.

So, if you (like many Aussies apparently) are living in a large home  and have more space than you know what to do with, now is a prime opportunity to cash in on it.  You can convert that empty,  unused, or spare  space into a regular extra income – simply advertise your space for rent, make some extra cash, and provide an opportunity for someone else in your community to save money on storage costs.
