Split the account by jurisdiction before you split it by asset class
Geography is the first cut in this market because it determines whether you can take the deal at all.
Start with three top level groupings: the District, suburban Maryland, Northern Virginia. Within each, break by asset class and then by submarket. That order matters, because the budget question you will be asked every month is where the money went, and the first answer needs to be a jurisdiction.
Set the targeting to location of interest rather than only location of the user. Someone sitting in Bethesda searching for Old Town Alexandria office space is a Virginia inquiry, not a Maryland one. Someone in New York searching Navy Yard retail is a real prospect. Radius targeting around your own office gets both wrong.
Draw the boundaries deliberately. A twenty mile circle from a downtown office covers three jurisdictions and a lot of water and parkland. Polygon targeting on the submarkets you actually work is more effort to set up and considerably cheaper to run.
If your firm is licensed in only one or two jurisdictions, exclude the others outright. Confirm the licensing position with your own counsel, then let the account reflect it.
