From here in Perth, capital of Western Australia, where I am visiting, the residential property boom looks somewhat different from the one we have experienced over the last ten years in most of the UK.  In the UK, we have become accustomed to explaining away the furious rise in the prices of homes in terms of supply and demand, i.e., there is insufficient supply to satisfy the demand, which is rising.  There is plenty of land, it is just that we will not let anyone build on the bits of it which are sited where people want to live.  We have surrounded our cities with greenbelt, and very nice it is too, but it does nothing to alleviate the lack of supply.  That lack of supply when coupled with a seemingly limitless supply of easy credit, secured against ever rising prices, has fuelled a tremendous boom.  Now that one of those elements may have been removed as the credit crunch takes hold, it may be that the market will grind to a halt.  The fact that supply is inflexible makes the residential property market inefficient, amplifying the boom and bust cycle.

In WA, some things are similar; the economy is booming creating a surge in demand and mortgages are relatively easy to obtain.  The residential property market in WA, and probably most of Australia, is dominated by new homes.  Not for Aussies the problems and expense of living in a home built for the needs of a different century.  Also, WA is hardly short of land; an area the size of Western Europe accommodates just two million people, mainly around Perth, which is growing at a frightening pace.  Of course, some suburbs trade at a premium as the rich prefer to congregate together but bulldozers carve out new land for building every year.  Want a home?  There is a plot ready and waiting for you to build upon.  This ever increasing urban sprawl brings with it other problems but short of land they are not.  Those hoping for a home in WA may have to wait up to two years for a builder to get around to them, though.

So why have house prices in WA and the rest of Australia been booming much like the UK (and the US, amongst others)?  I put it down to confidence in the economy and easy credit.  It does not really matter what you pay for your home so long as you believe that someone will buy it off you for more (the greater fool syndrome) and the borrowing is cheap and expected to remain so.  No one cares that they are paying twice as much for their home as they would have done ten years ago so long as it doubles in value over the next ten years.  Thus do asset prices lose any connection with the fundamentals.  What’s more, the more they go up, the happier we feel.  Warren Buffett has spoken rather disparagingly of those buyers who wish up the price of investments and it does seem a little irrational to draw comfort from the fact that you will have to pay a great deal more for your next purchase.

Whilst we were in the throes of the boom, here, as in the UK, those who should know better explain things away as being different this time.  If, as seems increasingly likely, this boom derails next year, the same commentators and economists will be telling us how it was all so blindingly obvious that it was going to end in tears.  We wait with bated breath.
