Marshall County is an income-versus-exit-liquidity question: income-focused buyers should investigate the published rent base, while buyers reliant on a quick resale should be cautious. The Zillow and Realtor observations both carry the 2026-06 label; Zillow’s county median home value rose 4.07%. FHFA’s 2025 repeat-transaction HPI rose 4.10% annually and 45.32% cumulatively over its five-year measure. Those methods cannot be averaged: FHFA is an appreciation index, not a dollar value. Meanwhile, Realtor.com’s MLS median listing price declined; that is active-market asking-price evidence, not a closed-sale result.
Measured median asking rent is $870 per month and supports the published 5.31% gross yield before costs. It is market rent, whereas HUD’s two-bedroom $959 Fair Market Rent is a payment standard and cannot substitute for asking rent. The 1.42% effective property-tax rate is a material carrying-cost input against the home-value and rent evidence. Expenses, insurance, financing, vacancy, repairs and property-level tax assessment are not published, so net yield and debt coverage cannot be computed.
Demand and competition are mixed rather than proven. Net migration was -53 tax-return households, and inbound movers’ average income trailed outbound movers’ by $4,447; this does not identify renter demand. QCEW annual covered employment at county workplaces fell 0.61% in 2025, with Manufacturing the largest disclosed private supersector; this is neither resident employment nor unemployment. Non-occupants accounted for 9.97% of purchase mortgages, so investor participation was a minority of total purchases rather than evidence of a buyer-led market.
Inland flood is the dominant hazard, while modeled annual climate loss equals 0.12% of building value; it is not a site-specific insurance quote or a dollar loss. Underwriting remains limited by absent flood-zone and elevation data, insurance quotations, property condition, closed-sale comparables, submarket vacancy and operating-cost evidence. Those gaps prevent a property-level conclusion on net cash flow, sale execution or flood exposure; next checks should tie each address to those records.
