Bon Homme County presents a thin-market underwriting tension: the June 2026 Zillow median home value is $183,452, and Realtor MLS data carry the same label, but the 2025 FHFA repeat-transaction HPI increased just 0.01% year over year. Investors needing dependable resale evidence or appreciation support should investigate closely; those dependent on a quick exit should be cautious. Zillow’s 6.23% year-over-year value change and FHFA’s 53.86% five-year cumulative index change are different methods and vintages, not a growth rate to combine.
County market asking rent is not published, so gross yield cannot be computed. HUD’s $929 FMR is a payment standard, not an estimate of asking rent, and cannot fill that gap. The 1.27% effective property-tax rate and $1,707 median annual tax identify a carrying-cost consideration, but neither establishes the tax on a particular property. Missing actual rents, insurance, repairs and vacancy prevent net-cash-flow or rent-to-price conclusions.
Realtor’s same-labeled MLS snapshot reports 62 median days on market, a 17.86% price-reduced share, and a 73.68% pending-to-active ratio. These are asking-market measures of marketing time, seller concessions and visible listing flow; they are neither closed-sale prices nor independent proof of buyer demand. Tax-return migration was net inbound, although entering movers had lower average AGI than departing movers. Investor purchases were 3.03% of reported purchases, or one of 33, indicating limited measured non-owner participation in that set, not all buyer competition. Annual QCEW workplace employment declined while weekly wages rose; it is covered employment at county workplaces, not resident employment or a forecast. Trade, transportation, and utilities is the largest disclosed private supersector, not the county’s entire economy.
Inland flood is the named dominant hazard, and modeled annual climate loss equals 0.13% of building value. That is a county-level modeled loss rate, not a property-specific flood determination; it warrants parcel flood-zone, elevation, insurance-quote and deductible checks. Confirm closed-sale comparables, rental asking and achieved rents, lease-up and vacancy, property-level taxes, condition and utility costs. Without them, an underwriter cannot establish market yield, net operating margin, exit liquidity or asset-specific climate exposure.
