The central underwriting tension in Hunterdon County is a $644,396 Zillow median home value in 2026-06 with no published market rent: income-focused buyers cannot calculate gross yield and should be cautious, while buyers who can verify asset-level rents and costs have a defined question to investigate. Zillow reports 2.81% year-over-year value growth; FHFA’s repeat-transaction HPI rose 6.32% in its separately labeled 2025 annual observation. Both are directional price evidence, but their methods and vintages differ, and neither is a closed-sale price for a particular home.
Carrying costs are the principal constraint on translating the value measure into economics. The effective property-tax rate is 1.93%, with a $10,001 median annual tax; parcel assessment and tax bills are needed before applying either figure to an acquisition. HUD’s $2,486 two-bedroom FMR is a payment standard, not observed asking rent. It cannot replace market rent, so gross yield and the relationship between rent, price, and taxes cannot be computed from this record.
Listing-market and household signals are mixed. Realtor.com MLS evidence shows active listings increased 9.90% year over year while median marketing time was 31 days. These are visible-supply and marketing-time measures, not closed-sale prices or standalone proof of buyer demand. Tax-return migration shows a net outflow of 188 households; incoming movers averaged $7,991 less AGI than those leaving. The supplied investor measure records 72 of 1,327 purchase mortgages, or 5.43%; it does not capture cash buyers or all buyer competition.
Risk screening should remain property specific. Modeled annual climate loss is 0.15% of building value, consistent with inland flood as the dominant hazard, but it is not an insurance quote or a property’s flood-zone determination. QCEW is annual covered employment at workplaces in the county, not resident employment. Missing insurance premiums, flood history, condition, financing terms, operating expenses, closed-sale comparables, and market rents prevent net cash-flow, property-level hazard-cost, and resale-liquidity conclusions.
