Months supply of vacant developed lots (VDL) is already low in many cities being considered for HQ2.
Months of supply represents the number of vacant lots currently 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 VDL supply is not available for Boston, Columbus, or Pittsburgh, so this chart accounts for 13 of the 20 cities on the shortlist. Source: Metrostudy
