An Arlington owner and a Petworth owner type two different searches
The metro head term is the least useful phrase in this market because it hides three buyers who cannot be served the same way.
Someone with one condo in Ballston does not search the way an investor holding three rowhouses in Petworth does. One is a first rental and a nervous owner. The other is a small portfolio with turnover, contractors and a lease calendar to defend.
Query language follows the housing stock. Inside the District, phrasing ties to rowhouses, converted flats, basement units and the neighborhood name: Shaw, Columbia Heights, Dupont Circle, Navy Yard. Out in Montgomery County and Fairfax County, the same intent arrives as single family rental, townhouse community and HOA rules.
Build the site on that split. One page per jurisdiction, then pages for the property types you actually take inside it. Neighborhood pages earn their place only where you have real detail to put on them: parking, alley loading, contractor access, what a turn typically involves in that housing type. A thin page named after a neighborhood is worse than no page at all.
The metro head term still deserves a page. Treat it as a brand page rather than as the strategy.
