The proportion of dwellings selling at prices that are lower than their previous purchase price is rising, and it is regions exposed to the resources sector that are taking the hit.According to CoreLogic's latest Pain and Gain report, an analysis of dwelling re-sales, 9.5 per cent of all dwellings re-sold in the June quarter were sold for less than their previous purchase price.This is an increase from 9.3 per cent in the March quarter and the highest proportion of "loss-making" sales since March 2014.Among dwelling that were re-sold for less than their purchase price the average loss was A$73,000 and the total loss was $459 million.Among dwelling that were re-sold for more than their purchase price the average profit was $262,550. Twenty-four per cent of homes re-sold during the quarter were sold for more than double their purchase price.The period of ownership is a factor in whether dwellings sell for a profit or loss. Dwellings that re-sold at a loss had an average length of ownership of 6.3 years, while dwelling that were re-sold at a profit were owned for an average of 10.3 years.Dwellings that re-sold for more the double their purchase price were owned for an average of 17.7 years.Capital city markets performed better than regional markets. The proportion of loss-making re-sales in the capital cities was 7.1 per cent in the June quarter (up from 6.9 per cent in March), while the proportion in regional areas was 14.1 per cent (up from 13.3 per cent in March).The proportion of loss-making re-sales in Sydney was a low 2.4 per cent and in Melbourne it was 4.4 per cent.Looking at dwelling stock, the proportion of houses that re-sold at a loss in the June quarter was 5.9 per cent in the capital cities and 12.2 per cent in regional areas.The proportion of units that re-sold at a loss was 9.5 per cent in the capital cities and 19.9 per cent in regional areas.Regions exposed to the resources sector recorded the highest proportion of loss-making re-sales: 33.8 per cent of dwellings in regional Western Australia 21.7 per cent in regional South Australia and 21.2 per cent in regional Northern Territory.CoreLogic said in a commentary: "Most major mining-linked regions saw an increase in their proportion of loss-making re-sales in the June quarter."Weakening commodity prices and lower demand for workers in these regions has led to falls in home values along with significant declines in rental rates. As a result, many home owners are looking to sell but there is a shortage of willing buyers."
