New research has found that property prices halved in many mining regions over the past decade. Property Investment Professionals of Australia (PIPA) chairman Peter Koulizos is currently reviewing research he undertook for a book that was published in 2008. As part of the new research, however, Mr Koulizos used CoreLogic data to calculate the best and worst performing areas over the past 10 years and found a clear front-runner for bottom of the pile – mining locations. “What this data shows us is that if you had bought property in one of these towns, not only did your property not increase in value over this 10-year period, but it is actually worth less,” Mr Koulizos said.
