As of 2017, there is less than a year's supply of new, detached single-family homes in 13 of the 20 cities being considered for HQ2.
Months of total housing supply represents the number of single-family homes under construction, models, and finished vacant inventory available, relative to number of homes sold per month.

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. Comprehensive data for single-family housing supply is not available for Boston, Columbus, or Pittsburgh, so this chart accounts for 13 of the 20 cities on the shortlist. Source: Metrostudy
