The District of Columbia is the country's only single-MSA jurisdiction on this checklist — capital-city economics, federal-government employment scale, and 90-day evictions with statewide rent control shape every underwriting decision. Price-to-income 4.46, cap rate proxy 3.2%, median home $724,600, across 672,079 residents within the District itself. 0.58% effective property tax is low for the entry price level; 10.75% top local income tax.

The FHFA HPI is up 21.3% over five years and -2.0% last year — the negative year-over-year number reflects post-pandemic federal workforce redistribution and remote-work effects on DC-specific demand. Builders pulled 1,377 permits TTM at 2.0 per 1,000 residents. Net migration at −0.34% is meaningfully negative — the country's third-steepest out-migration at jurisdiction scale. Unemployment sits at 4.4% with median household income at $106,287.

The District is part of Washington-Arlington-Alexandria — the single MSA that spans DC, Virginia, Maryland, and West Virginia (6.3M metro population). Federal government is the employment anchor: all three branches plus the majority of federal regulatory agencies, think tanks, lobbying infrastructure, and consultants. Owner-occupancy inside DC proper sits at 41.1% — the country's lowest and the lowest in the Northeast cohort by a wide margin; this is a majority-renter city.

Against Maryland and Virginia (the two states that share the MSA), DC has the lowest property tax but the highest income tax and the most restrictive tenant law (statewide rent control). Against New York City, DC has lower property tax and slightly shorter eviction timeline but similar tight cap-rate math. Against the country's other institutional-labor capitals (Boston, San Francisco), DC's underlying demand is more volatile because federal employment shifts with administrations.

Operating environment is slow and restrictive. 90-day eviction timeline, statewide rent control (Rental Housing Act of 1985 + subsequent amendments), 1-month deposit cap, 41.1% homeownership, 9.7% vacancy. Insurance averages $1,143/yr. 10.75% top local income tax. 63.6% of residents hold a bachelor's degree — the country's highest concentration.

So what does an investor do?

• Cash flow: Not DC's thesis at the state-level rollup. The 3.17% cap proxy + 10.75% income tax + 90-day eviction combination makes passive cash flow unworkable without active local management. Specific submarket plays exist (certain Class B apartment buildings in emerging neighborhoods, but those are institutional-scale deals).
• Appreciation: Historically stable but structurally slowing. The 21.3% five-year HPI is the cohort's weakest by a wide margin, and year-over-year is negative. Remote work and federal-workforce redistribution have genuinely changed the demand equation; don't underwrite DC appreciation on pre-2020 patterns.
• Out-of-state: DC is a specialist market — most non-institutional investors are better served by the Maryland or Virginia sides of the MSA (Hagerstown-Martinsburg MD, Baltimore-Columbia-Towson MD, Richmond VA, Virginia Beach-Norfolk-Newport News VA). The same federal-employment exposure at materially better underwriting math.
