New York County is a rent-growth-versus-basis-and-carrying-cost case: investors who can validate unit-level expenses and tenant demand should investigate, while yield-sensitive buyers should be cautious. In Zillow county data labeled 2026-06, median home value is $1,217,330, up 2.28%, and median asking rent is $4,833 monthly, up 6.82%. The supplied gross yield is 4.76% before expenses. Faster asking-rent growth than value does not establish durable income, but it makes expense verification central rather than treating appreciation as the thesis.
Measured market rent—not HUD FMR—supports that gross-yield figure. HUD's two-bedroom FMR is $2,910, a payment standard, while market asking rent is 166.1% of it; FMR cannot be substituted for rent or yield. The effective property-tax rate is 0.92%, and median annual property tax is $10,001. Those county figures flag carrying-cost exposure but do not specify tax for a target unit or net operating income; insurance, common charges, maintenance, vacancy and financing data are not published, so net yield cannot be underwritten.
County QCEW data for 2025 report 2,487,868 annual average covered jobs located at workplaces, with Professional and business services the largest disclosed private supersector. This is neither resident employment nor unemployment, and it does not itself demonstrate tenant demand. Tax-return migration records a net gain of 4,272 households, but inbound movers' average AGI was $44,295 below outbound movers'. Investor mortgages accounted for 6.2% of purchase mortgages. That combination requires unit-specific renter and purchaser evidence rather than a broad demand conclusion.
Risk limits are material. Inland flood is the dominant hazard, and modeled climate loss is 0.09% of building value per year; it is a modeled ratio, not a property insurance quote or dollar loss. No FHFA annual observation is published, so a repeat-transaction price-index check on Zillow's direction is unavailable. Realtor.com listing price, active inventory, days on market and price-reduction evidence are also not published, preventing an assessment of visible MLS supply, marketing time or seller concessions. Next checks are unit flood and insurance records, assessed tax and charges, executed rents, and current comparable listings and transactions.
