"There has been clear evidence of weaker housing market conditions over the second quarter of 2013. The housing market is highly seasonal and we anticipated a slowing of conditions over the current period however, it is likely that the magnitude of the slowdown and subsequent value falls has been heightened by falling consumer sentiment. Should this continue, it is reasonable to anticipate a less active housing market where value growth is lower than when confidence was much more buoyant."
