Marshall County has a basis-versus-income tension: it warrants property-level investigation where asking rents and flood costs can be documented, but cautious underwriting where price evidence is unresolved. Zillow’s county median home-value measure fell 7.36% at 2026-06, whereas FHFA’s repeat-transaction HPI rose 8.30% in 2025. They use different methods and labeled periods, so they cannot be merged into one appreciation result; nor is either a closed-sale price.
At Zillow’s 2026-06 county observation, the $199,177 median home value and $975 monthly median asking rent support the supplied 5.87% gross yield before costs. The 0.72% effective property-tax rate is a carrying-cost input, not a complete expense estimate. HUD’s two-bedroom FMR is a payment standard, not an estimate of asking rent, so it cannot replace the measured rent or be used to infer yield. Insurance, maintenance, utilities, vacancy, and financing costs are not published; net yield cannot be determined.
Realtor.com’s MLS listing-market evidence shows inventory down 23.28% year over year and 22.53% of listings price-reduced. Fewer visible listings can tighten choice, while reductions signal seller concessions; neither is a closed-sale price or proof of buyer demand. Tax-return migration was net positive by 57 households, but movers in had average AGI $1,234 below movers out, limiting the income signal. Investor purchase mortgages accounted for 19 of 290 total purchases. QCEW annual covered employment at county workplaces declined, and Manufacturing is the largest disclosed private supersector; neither describes resident employment or the whole county economy.
Inland flood is the dominant disclosed hazard, and modeled climate loss equals 0.21% of building value per year; it is modeled loss rather than a property-specific flood determination. Next checks are parcel flood zone, insurance quotations, elevation and condition, lease roll, vacancy, financing terms, and recent closed comparables. Their absence prevents a net-income conclusion, a property-level hazard-cost assessment, and verification that MLS asking conditions will execute.
