Home loans to investors have fallen to the lowest level in 10 months following a regulatory clampdown and the Turnbull government's efforts to cool the Sydney and Melbourne housing market.

Figures released by the Australian Bureau of Statistics on Monday show home loans to investors as a proportion of all loans dropped 1.25 percentage points in March to 48 per cent, down from a high of over half of all home loans in January.

The slide has triggered a dip in property prices across five of Australia's capital cities, fuelling speculation of the end of the property boom.

The latest results from CoreLogic show the price of homes across Sydney, Melbourne, Brisbane, Adelaide and Perth falling by 0.5 per cent for the week and 0.9 per cent for the month.
