The latest RP Data-Rismark home price data shows prices have changed little since March - a result that will please the Reserve Bank and help keep rates down.As the graph shows, prices were growing rapidly as recently as March. At the end of that month, RBA governor Glenn Stevens warned that "it is a mistake to assume that a riskless, easy guaranteed way to prosperity is just to be leveraged up into property." In June he said the RBA wanted to avoid further big rises in household debt - essentially housing debt.But the latest data shows home prices now are where they were when Stevens issued his March warning. The RP Data-Rismark Hedonic Home Value Index for capital cities, released yesterday, is down 0.3 per cent over three months. It climbed a seasonally adjusted 0.4 per cent in July, after sliding 1 per cent in June.A string of six 0.25 per cent rate rises since October 2009 appears to have cautioned buyers; Stevens' warnings may also have had some effect.
