* Using the increase in Seattle's average new and existing home price as a base (2010 v. 2017), we’ve projected the potential impact of Amazon in 16 of the 20 cities being considered for HQ2. For a more comprehensive picture of the housing market in each city, we pulled Metrostudy data by CBSA; New York City and Newark, as well as Washington, D.C., Montgomery County, Md., and Northern Virginia, are represented as one market. This accounts for 16 of the 20 cities on the shortlist, but is representative of the candidate cities as a whole.
