McDonald County presents an appreciation-versus-income-underwriting tension: Zillow's 2026-06 county median home value was $239,323, up 5.64% year over year, but no county market asking rent is published. Income-oriented or leveraged buyers should investigate unit economics before treating appreciation as support; buyers able to validate leases and flood costs have a narrower question—whether carrying costs fit actual rents. This is county-level screening, not evidence for a particular property.
Zillow’s value observation and FHFA’s 2025 repeat-transaction HPI measure different constructs. FHFA rose 9.27% annually and 85.34% cumulatively over five years. It corroborates a positive price direction but is not a home value and cannot be averaged with Zillow growth because method and vintage differ. HUD’s two-bedroom FMR of $888 monthly is a payment standard, not market asking rent; absent market rent, gross yield cannot be computed. The effective property-tax rate is 0.46%, a carrying-cost input to test against actual assessed tax and rents.
Realtor.com’s 2026-06 MLS snapshot showed inventory rising year over year, a 29.49% pending-to-active ratio, and 20.4% of listings price-reduced. Those are visible-supply, pipeline and seller-concession signals, not closed-sale prices or proof of buyer demand. Tax-return migration was net -55 despite incoming movers’ average AGI being $8,022 higher than outgoing movers’; this does not establish tenant demand. Investors made 21 of 198 purchases, a present but not dominant competition measure.
Modeled expected annual building-value loss is 0.32%, and inland flood is the dominant hazard; this is modeled county-level exposure, not parcel insurance pricing or a predicted claim. QCEW describes annual covered employment at county workplaces, not resident employment or unemployment; Manufacturing is the largest disclosed private supersector, not the entire economy. Next checks are property-level flood zone and insurance quotes, assessed tax, executed and asking lease comps, vacancy and turnover, and closed-sale comps. Missing rent blocks yield; missing parcel risk blocks a full carrying-cost conclusion.
