New York County

New York County posts a median home price of $1,247,381 against median rent of $4,779, producing a gross rent-to-price ratio of 4.60% and a cap rate of just 2.99%. Those numbers place it squarely at the appreciation end of the spectrum, with almost no current-income story to tell. The model's base-case underwrite, at 6.85% financing with 20% down, generates negative $3,433 per month in cash flow and a cash-on-cash return of negative 14.36%. Year-over-year price growth came in at 3.2%, which is positive but not aggressive enough to paper over that carry deficit in the near term. An overall score of 44 out of 100, with a cash-flow sub-score of 39 and an affordability index of zero, confirms what the raw numbers already show: this is not a market you enter for yield.

The buyer this market suits is a long-horizon appreciation investor with substantial liquidity who can absorb negative carry indefinitely, or an institution or high-net-worth individual playing for terminal value and treating the rental income as a partial offset rather than a return driver. The cash-flow buyer has no realistic path here: even eliminating the mortgage entirely, a 2.99% cap rate on a $1.25 million asset implies gross operating income that barely covers taxes, insurance, and maintenance before debt service enters the picture. A value-add operator faces the same ceiling, since the rent-to-price ratio at 4.60% leaves almost no margin to manufacture yield through renovation. The appreciation score of 81 is the one number that defends the market's existence in a buy-and-hold context, and that score reflects the county's historical price trajectory, density constraints, and sustained demand from a concentrated, high-income renter base.

The carry costs deserve a dedicated line on any underwrite. Property taxes at the New York state-average effective rate of 1.72% translate to an estimated $21,455 annually on the median asset, and insurance adds another $2,994, putting the combined monthly tax-and-insurance burden at roughly $2,037. That figure alone is 43% of the median rent and must be modeled explicitly before anything else. The 1.72% rate is flagged as high, and the honest caveat is that this is a state-average estimate from Tax Foundation 2024 data; actual county and township rates in Manhattan can deviate meaningfully, so a parcel-level tax lookup is non-negotiable before closing. At that rate, the tax and insurance line sitting at $2,037 per month is not a rounding error, it is a primary expense category.

New York County's single sharpest underwriting risk is concentration: the entire investment thesis rests on one market continuing to attract high-income renters and appreciating in nominal terms faster than the carry cost compounds. Regulatory exposure is real and material. New York City's rent stabilization and rent control framework applies to a large share of the multifamily stock, and any acquisition of a rent-stabilized building requires underwriting the legal rent roll, not the market rent. Purchasing into a regulated unit at a cap rate of sub-3% with a rent ceiling that limits upside is a structurally different risk profile than a free-market unit, and the blended county-level figures presented here do not distinguish between the two. Demographic stability is supported by population scale at 1.645 million, but affordability at an index of zero signals that the existing renter base is under pressure, which introduces turnover and concession risk if rent growth stalls.

Against its neighbors, New York County is the highest-priced and lowest-yielding option in the set. Kings County (Brooklyn) offers a nearly identical rent-to-price ratio of 4.61% at a median price of $915,205, meaning a buyer gets comparable gross yield at roughly 73 cents on the dollar relative to Manhattan entry cost. Queens County posts the best rent-to-price ratio in the peer group at 4.99% and a median price of $722,489, making it the most accessible cash-flow-adjacent market among the five neighbors, though still not a genuine cash-flow market at scale. Rockland County comes in at 4.89% on a $724,554 median, with an overall score of 51 versus New York County's 44. Richmond County and Westchester County both trail on rent-to-price at 4.12% and 4.39% respectively, offering no clear advantage over the subject market on yield while lacking the appreciation argument that Manhattan carries.

Choose New York County over any of its neighbors only if the investment thesis is explicitly long-duration appreciation, the buyer has the balance sheet to carry negative $3,433 per month without forcing a distressed exit, and the specific asset is either free-market or priced to reflect its regulatory status. For any investor whose model requires income from day one, Queens or Rockland present better entry math at a fraction of the capital commitment.
