Piatt County presents a valuation-and-carrying-cost question, not a demonstrated income case: investors able to independently verify rents and flood costs should investigate, while yield-led buyers should be cautious. Zillow’s county median home value was $229,717 in 2026-06, up 2.49% year over year. FHFA’s 2025 repeat-transaction HPI gained 1.20% annually; it confirms positive index movement but is not a dollar value and does not share Zillow’s observation period or method.
Market rent is not published, so gross yield cannot be computed. The $1,122 HUD FMR is a payment standard, not an asking-rent estimate, and cannot replace missing rent. Carrying-cost screening should retain the 1.81% effective property-tax rate and $3,265 reported median annual tax alongside price. Inland flood is the dominant hazard; modeled climate loss equals 0.19% of building value per year, requiring parcel-specific insurance, elevation, and flood-zone review.
Tax-return migration was net -28, although arriving households averaged $6,472 more AGI than leavers. QCEW annual covered employment at county workplaces increased; this is not resident employment, and Trade, transportation, and utilities is the largest disclosed private supersector, not the whole economy. Realtor.com MLS evidence shows 29 active listings, 60 median days on market, and a 17.16% reduction share—visible asking supply and seller concessions, not closed prices or demand proof. Investors made up 6.55% of 229 purchases, a buyer-participation measure, not a rental-demand measure.
Risk limits remain material. County-level climate modeling cannot establish a parcel’s flood exposure or insurance terms, and MLS listings cannot establish executable sale prices. Missing lease comparables, actual rents, vacancy, closed sales, property condition, insurance quotes, financing, and assessment history prevent a defensible net-cash-flow, valuation, or resale review. Next checks are address-level flood determinations and elevation, insurance and tax documentation, rent rolls or lease comps, closed comparables, and contract terms. County migration and workplace data cannot establish a specific property’s tenant base.
