Boise has grown into a genuine urban STR market, while Sun Valley and McCall run mature resort economies that attract serious investor capital. A long tail of remote and recreational properties rounds out the state, each with its own access and response-time questions.
What underwriters ask forWildfire documentation leads: most carriers want current defensible-space evidence before writing mountain and foothill properties, and smoke seasons have made even non-burn losses, soot, air handling, cancellations, part of the conversation. Elevation drives pricing, with high-country properties facing meaningful surcharges, and snow-load engineering is a real underwriting question for older structures. Resort-market owners should look hard at how loss-of-income limits are valued against peak-season revenue, the same trap as Colorado.
Wildfire claims are denied on stale or missing mitigation records. Loss-of-income payouts get capped at shoulder-season rates in resort markets. Snow-damage claims fail without structural maintenance evidence, and elevation misstatements on applications surface at the worst time, after a loss.
Idaho law limits how far local governments can go in banning short-term rentals, which keeps the state broadly open, but resort municipalities like Sun Valley and McCall still run real permitting regimes, and Boise has been building out its own licensing requirements. Friendly is not the same as rule-free.
