Duchesne County presents a measured-but-unresolved underwriting tension: positive county price indicators and a small positive migration balance sit beside slower MLS conditions, no published market rent, and inland-flood exposure. It warrants investigation by buyers able to validate unit-level rent, insurance, and flood controls; leverage-sensitive underwriting should be cautious. Zillow's county median home value was $376,136 in 2026-06, up 3.96% year over year. FHFA's repeat-transaction HPI increased 4.68% in 2025. These independently point upward, but they use different methods and labeled periods; the HPI is not a home value and their growth rates cannot be combined.
Housing economics cannot yet support a gross-yield test: county market asking rent is not published. HUD's two-bedroom FMR is a payment standard rather than market rent, so it cannot substitute for rent or be used to infer yield. The effective property-tax rate is 0.61%, with median annual tax of $1,742. Those are carrying-cost inputs, but they do not establish the tax bill on an acquisition or offset absent insurance, maintenance, financing, and rent evidence.
In the 2025 QCEW annual workplace series, covered employment rose 2.23%; Trade, transportation, and utilities was the largest disclosed private supersector, not a description of the entire economy. MLS listing evidence at 2026-06 shows 84 active listings, up 9.87%, alongside 73 median days on market, up 10.19%, and 11.2% of listings reduced. This visible supply and concession pattern merits diligence, not a buyer-demand conclusion. Net migration was 20 households, and incoming movers' average AGI exceeded outgoing movers' by $8,911. Investor mortgage share was 7.08% of 212 total purchases; that limited participation should be read against the total purchase count, not as a measure of all investor ownership.
Modeled annual climate loss equals 0.09% of building value, and inland flood is the dominant hazard; this is a modeled portfolio-style loss ratio, not a property loss estimate. Not supplied: flood-zone, insurance-quote, property-condition, market-rent, vacancy, operating-expense, sale-price, and financing evidence. This prevents a property-level cash-flow or resilience conclusion. Next checks are address-specific flood and insurance documentation, comparable asking rents and executed leases, and purchase terms versus tax and operating costs.
