Deer Lodge County presents a carrying-cost tension: Zillow’s $300,272 county median home value in 2026-06 rose 2.85%, while FHFA’s 2025 repeat-transaction HPI rose 1.80%. Both point upward, but they use different methods and vintages and cannot be combined. The question is whether published rent and inward-moving tax households can support ownership costs despite a shrinking covered-job base and flood exposure. It merits property-level investigation; buyers dependent on stable employment or low insurance costs should be cautious.
The published median asking market rent is $1,140 per month, generating the reported 4.56% gross yield before operating costs against the value measure. HUD FMR is $1,080 per month and is a payment standard, not an asking-rent estimate; the market-rent figure is higher, but that does not validate collections or affordability. The $1,803 median annual property tax is a concrete carrying cost alongside undisclosed insurance, maintenance, vacancy and financing costs. Gross yield therefore cannot be read as net income. Rent-roll, vacancy, expense and property-specific assessment data are not published, preventing an NOI or debt-coverage conclusion.
Annual QCEW reports 3,371 covered jobs at county workplaces, down 1.49%; this is neither resident employment nor unemployment. Education and health services is the largest disclosed private supersector, not the whole county economy. Net migration was 62 tax-return households, and incoming movers’ average income exceeded outgoing movers’ by $6,774, a potentially favorable composition signal rather than a measure of tenant demand. Investors accounted for 5.95% of 84 purchase mortgages, showing limited financed investor participation but not measuring cash buyers or total sales.
Inland flood is the dominant hazard, and modeled expected annual climate loss equals 0.08% of building value; it is a model, not a site-specific insurance quote or realized loss. Realtor.com MLS listing price, active listings, days on market and reduced-share data are not published, so visible supply, seller concessions and marketing time cannot be underwritten. Flood-zone status, elevation, insurance quotes, lease comps, property condition and closed-sale evidence are next checks; without them, neither exit liquidity nor risk-adjusted cash flow can be established.
