Vacancy rate is basically a property manager's KPI. Additionally, data is collected by the REIV which has no interest in providing bad news about investing in property. https://s.zoomerang.com/s/REIV-January-2013-Vacancy-Survey

REIV vacancy rate is (unleased property on the books) / (property on the books). It's always going to be an under-estimate of true vacancy due to properties that are empty full time and those that are privately managed and temporarily vacant.
