New York-Newark-Jersey City, NY-NJ-PA

New York is the country's most expensive entry ticket — and the data says it's still working. The metro sprawls across 23 counties in NY, NJ, and PA holding 19.9 million people — three times Houston's footprint, the largest in the country by a margin. The federal House Price Index compounded +42.8% over five years, pushing the price-to-income ratio to 6.03× at a $97,334 median household income. Year-over-year HPI growth is still running at +4.62%, faster than nearly every Sun Belt comparable. None of this fits the standard "expensive coastal metro is plateauing" narrative — the line keeps grinding up.

The action inside the metro is unusual: the boroughs are building harder than the suburbs. The five NYC counties account for 23,360 of the metro's 49,613 building permits in the trailing twelve months (Census BPS), and the suburban ring is contracting:

• Brooklyn (Kings County) — 2.7M residents, 6,965 permits TTM, –4.9% YoY. Median home value: $889,700. The biggest builder despite the slight slowdown.
• Bronx County — 1.4M residents, 6,282 permits TTM, +7.0% YoY. The most affordable borough at a $49,036 median household income — and the one quietly building the second-most.
• Manhattan (New York County) — 1.6M residents, 3,311 permits TTM, +49.1% YoY. The biggest single-county acceleration in the metro. Median home value: $1.1M.
• Suburban ring is cooling — Suffolk (–13.4%), Nassau (–3.8%), Westchester (–1.3%). The classic NY suburban-flight pattern of the 2010s has reversed: people want the boroughs again.

Net migration was −100,480 returns in the most recent vintage from the IRS Statistics of Income — −0.50% of population, a substantial net loss. The gross flows are still enormous (roughly 439,000 returns arriving and 539,000 leaving), so NY is a high-churn metro — but the direction is outflow. That isn't a surprise: coastal expensive metros have been shedding returns to the Sun Belt for years, and the IRS data is the cleanest signal we have of it. The magnitude is meaningful — roughly 100,000 returns lost per year from the country's largest metro. BLS unemployment sits at 4.5% (Bureau of Labor Statistics LAUS) — looser than the Sun Belt comparables, which is normal for a deep, diversified urban labor market. The HUD Fair Market Rent for a 2-bedroom is $2,763 (HUD User) — pricing the metro into the rent-burdened category at 34.1% of the median household's income — and the cap rate proxy is 3.7%, which is what "tight" actually looks like on a chart.

So what does an investor do with all of this?

• If you're hunting cash flow, this is the wrong metro. A 3.7% cap rate proxy means even the above-average property doesn't pencil at standard expense ratios. NY is for capital preservation, not yield. Look at Houston or Detroit instead.
• If you're playing appreciation, this is the strongest big-metro story in the country. Five-year HPI of +42.8% with year-over-year still running at +4.62% — and the build pipeline is concentrated in the boroughs, not the suburbs, which means the supply story does NOT bail out the suburban-ring buyer. Manhattan and Brooklyn are where the math works for an appreciation thesis.
• If you already own here, the data says hold and avoid the suburbs. The five boroughs are out-permitting the ring three-to-one — that's where the velocity is, that's where rents and values keep compounding from here.
