Big Horn County presents a diligence-first tension for investors: Zillow’s county median home value was $295,214 in 2026-06, up 3.9% year over year, while FHFA’s 2025 repeat-transaction HPI rose 8.45% annually and 71.05% cumulatively over its supplied multiyear measure. These are not comparable growth observations: FHFA is an index rather than a dollar valuation and its period differs. Buyers relying on appreciation alone should be cautious; investigators should test whether property-level rents and resale liquidity support the value basis.
Housing economics are unproven because a county market rent is not published. HUD’s two-bedroom FMR is $963 per month, but it is a payment standard, not an asking-rent estimate; gross yield therefore cannot be computed. The effective property-tax rate is 0.55%, with median annual tax of $1,198, a known carrying-cost input but not a full operating-cost measure. Underwriting needs achieved rents, vacancy, insurance, utilities, maintenance and property-specific tax bills before a price-to-income conclusion.
Realtor.com’s MLS evidence complicates the value signal: visible active supply was higher, marketing time was longer, and price reductions indicate seller concessions rather than closed-sale pricing; its pending-to-active ratio was 56.44%. Net migration was negative 20 households, despite average AGI for inbound movers exceeding outbound movers by $14,661. Investor buyers represented 6.41% of 78 purchases, a limited observed mortgage-purchase share, not proof of broad buyer competition.
Risk control is central: inland flood is the dominant hazard and modeled annual climate loss equals 0.21% of building value, not a property-specific claim or dollar loss. QCEW records covered-workplace employment and wage gains, with Natural resources and mining the largest disclosed private supersector; it is neither resident employment nor an economic forecast. The thesis can fail if unobserved market rents do not cover costs, MLS conditions do not translate into executable exits, or parcel-level flood insurance and exposure exceed assumptions. Next checks are signed leases, closed-sale comps, flood maps and insurance quotes, and property-level expense histories.
