That said, while the fundamentals for healthcare-related properties are not impervious to economic cycles, the healthcare and education sectors of the labor market have been the only sectors to show meaningful growth in 2008.1 In economic downturns, healthcare properties, such as medical office buildings, tend to perform better than other real estate property types. This is most likely because people still get sick in a slowing economy and the key drivers of demand for healthcare properties are related to an aging and growing demographic population.² Grubb & Ellis Healthcare REIT continues to search for and purchase strong assets. As a result, we believe the overall portfolio is well-positioned for the future. Your participation in Grubb & Ellis Healthcare REIT may provide you additional portfolio stability during these volatile times. Thank you for your continued confidence in Grubb & Ellis Healthcare REIT. Scott D.
