6. Boston
Boston boasts a plethora of colleges and universities, including Harvard, MIT and Tufts, and remains an international center of higher education for law, medicine, engineering, technology and business. Boston is one of the world’s leading cities for innovation, entrepreneurship and start-ups and attracts more venture capital any other U.S. market. The region's economic drivers include life sciences and biotech, high tech, finance, healthcare and government services. The city's office market fundamentals remain strong, and Pontius says it would weather a recession well despite a recent increase in new office construction. Boston’s metro-wide office pipeline doubled to 6.6 million sq. ft. since the end of 2018. However, there is no concern about over-supply, because severe supply constraints for large blocks of space in the Boston and Cambridge markets will persist through 2020, and 91 percent of new space is pre-leased, according to a JLL report.
