Medical office buildings remain strong investor favorites despite slowing transaction volume, which one expert says may persist for the next few quarters. 

"The past several years have been banner years for investors with historically low cap rates and many more buyers in the market than sellers," says Julie A. Johnson, Executive Vice President, Arizona at Colliers, who will be speaking on a panel of industry experts breaking down healthcare real estate trends at this week's GlobeSt healthcare conference. But "medical office buildings will continue to be strong with not only the increase of the senior population but also the population increase in many markets, specifically the Sun Belt cities."

Johnson notes that construction costs have been "a bit of a headwind," as have labor shortages and increased labor costs for retaining existing providers.
