Less than 45 minutes to the renowned Madison River, the historic O’Brien House offers a rare blend of character, updates, and flexibility. This “small historic estate” is framed by a wrought iron fence, mature landscaping, and established grounds with fruit trees and a brick patio. Inside, you’ll find 12’ ceilings, original architectural details, and inviting living spaces, complemented by thoughtful updates including a remodeled kitchen with granite countertops and upgraded electrical (2020), new roof (2020), and new sewer line (2020). The home offers 2 bedrooms and 1.5 bathrooms, plus a sunroom with custom stonework and a flexible office/library space. A true standout is the attached additional living space, connected through the sunroom—ideal as a private third bedroom suite or as a separate 1-bedroom apartment with kitchenette and ¾ bath for income potential. Additional features include underground sprinklers, drip systems, a powered homestead cabin relocated from Granite Creek—located near Virginia City, once the territorial capital of Montana and a central hub during the 1860s gold rush—and an equipment shed. A rare opportunity to own a historic property that lives well for both everyday comfort and long-term versatility.
