Niagara County’s tension is a rising price-and-rent backdrop against carrying-cost, flood and demand-validation limits. It merits file-level review for buyers who can verify insurance and leasing economics; buyers relying on quick resale or thin operating margins should be cautious. Zillow’s 2026-06 county median home value was $259,222, up 6.79% year over year. Separately, FHFA’s annual 2025 repeat-transaction HPI rose 6.6%. Those measures point in the same direction, but FHFA is an index rather than a home value and their vintages and methods should not be combined.
The supplied market rent is a $1,159 monthly median asking rent, up 7.42% year over year, and reported gross yield is 5.37% before costs. That is usable rent evidence, but it is not HUD rent: market rent is 86.3% of the $1,343 two-bedroom HUD Fair Market Rent, a payment standard rather than an estimate of asking rent. The reported effective property-tax rate is 2.19%; because yield is gross, tax, insurance, repairs, vacancy and financing remain outside it. Underwrite those expenses at property level rather than treating county yield as cash flow.
Tax-return migration was negative, while households moving in had average AGI $1,247 above those moving out. This is mixed household-flow evidence, not proof of rental demand. QCEW’s annual county workplace series shows covered employment up 0.79% and average weekly wages up 5.23%; it measures covered jobs at county workplaces, not resident employment or unemployment. Trade, transportation, and utilities is the largest disclosed private supersector, not the entire economy. Investors represented 6.73% of purchase mortgages, indicating some non-owner participation but not bidding pressure or transaction-wide competition.
Modeled expected annual building-value loss is 0.12%, and inland flood is the dominant hazard; neither result identifies parcel-level exposure or insurance cost. Realtor.com MLS listing-market figures are not published, so visible supply, seller concessions, marketing time and pending activity cannot be assessed from active listings, price-reduction share, days on market or pending-to-active ratio. Missing vacancy, operating-expense, insurance and parcel flood evidence prevents net-income underwriting. Next checks are parcel flood-zone, elevation and drainage review, insurance terms, property tax bill and local rent and vacancy comps.
