Welcome to 29 & 31 South Rodney Street, a historic side-by-side brick duplex located on what many locals consider the coolest street in town. Rich with historic character, this downtown property features two spacious 3-bedroom, 1.5-bath two story residences, each thoughtfully designed with comfortable living spaces, crawl-space storage, and both front and back yards. Whether you're an investor, owner-occupant, or someone looking to offset your housing costs while living in one of Helena's most desirable neighborhoods, this property checks every box. The north unit is occupied by a long-term tenant, providing immediate rental income and stability. The south unit is owner occupied and showcases numerous updates, including new flooring, an updated kitchen, and a one-car garage. Recent improvements include the new tongue and groove timber frame porch, new windows installed this summer, new water and sewer services, new gutters and a newer furnace installed in 2017. The property has underground sprinklers as well. And the location? It doesn't get much better. South Rodney Street is hip and unique, walking distance from both trails and downtown, with its own corner store, bakery, and dive bar. The recent addition of four new-construction townhomes as neighbors has only enhanced the appeal and investment potential of this vibrant block. Enjoy the charm of downtown living with easy access to local restaurants, shops, parks, entertainment, and all that Helena has to offer, right outside your front door. This is more than a duplex. It's a chance to start a downtown property portfolio, live in one unit, generate income from the other, and grow your investment in one of Helena's most desirable neighborhoods.

Helena South-Central Historic District, located between Last Chance Gulch and Mount Helena City Park, is a historic and walkable Helena neighborhood with brick streetscapes and porch-lined Victorian-era homes. The neighborhood’s character concentrates around the Last Chance Gulch Pedestrian Mall near Sixth Avenue, where coffee counters, galleries, and small storefronts set a steady downtown rhythm. Architectural details run from ornate Queen Anne trim to sturdy early-20th-century brickwork, with mature trees softening the blocks. The Myrna Loy anchors local film and live performance in a restored downtown setting. The Holter Museum of Art and the Grandstreet Theatre add gallery nights and stage lights to the calendar. Trails and overlooks rise quickly at Mount Helena for a change of pace.
