The aging population in the US is stimulating growth in the medical office building market, according to a Marcus & Millichap 2007 report.  By the end of 2007, 14.5 million square feet of medical office space is expected to be developed, up from 13.2 million square feet in 2006.  Median sales prices are up 6.4% compared to last year, with the number of transactions completed up by 9%.  Expect this trend to continue as the baby boomers move steadily into retirement, and the demand for medical services and doctors grows. 

Another new trend; in some metro markets (including Denver) physicians are more and more likely to invest in office condominiums, spurring the demand and construction of more of this product.
