Big Stone County has a valuation-versus-income-underwriting tension: a rental buyer should investigate whether the recent county value move is supported by property-level rent, while remaining cautious about buying from a headline measure alone. Zillow reports a $205,123 county median home value for 2026-06, up 10.94% year over year. FHFA’s repeat-transaction HPI rose 3.12% in 2025. These are different methods and observation periods; the HPI is not a home value, and neither measure substitutes for closed comparable-sale review.
Measured market rent is not published, so gross yield cannot be computed. HUD’s two-bedroom FMR is $973 per month, but it is a payment standard rather than an asking-rent estimate and cannot fill that gap. Carrying costs warrant explicit parcel review: the effective property-tax rate is 0.87%, with median annual tax of $1,473. The record lacks insurance, operating expenses, vacancy, and property-level assessed values, preventing net-cash-flow or tax-bill underwriting.
Demand evidence is mixed and county-specific. QCEW records 1,742 annual-average covered jobs at county workplaces, up 2.83%; it is not resident employment or an unemployment measure. Education and health services is the largest disclosed private supersector, not a description of the full economy. Tax-return migration was net negative by 17 households, although arriving movers had a $9,583 higher average income than departing movers. Non-owner investors accounted for 8 of 56 purchase mortgages, a 14.29% share: competition exists, but the count is small and does not establish pricing power or tenant demand.
Inland flood is the dominant hazard, and modeled annual climate loss equals 0.12% of building value; this is a modeled expected-loss ratio, not a claim about any parcel’s flood exposure. The record publishes no Realtor.com listing price, active-listing, days-on-market, or price-reduction figures, so MLS asking-price, visible-supply, marketing-time, and seller-concession conditions cannot be assessed. Next checks are flood-zone and insurance quotes, achievable market rent, lease-up evidence, property taxes, and sale comparables.
