Speculative Vacancy Reports

The Speculative Vacancies report was born in 2007 when Karl Fitzgerald noticed a disparity between media headlines decrying a ‘record low land supply’ and the dozens of vacant homes he passed on his daily bicycle commute. Since then, Prosper Australia has investigated the role of vacant land and housing on housing affordability in Melbourne. Water usage data provided by Melbourne’s water authorities is measured as a proxy for vacancy. Speculative Vacancies are determined when sites are found to have abnormally low water consumption over a full twelve-month period.
