    Overview

    Built in 1941, this triplex offers two main-level 1–2 bedroom, 1-bath units with separate entries, full kitchens, and comfortable living spaces. The main level includes 9-foot ceilings and classic built-ins. The lower level features a spacious 2-bedroom, 1-bath unit with its own living area, kitchen, and plenty of storage. A basement laundry setup serves the units.

    Outside, the property presents a durable metal roof, fresh exterior paint, mature landscaping, and a newer vinyl fence. A detached 1-car garage supports off-street parking and storage needs. The home is located at 345 N 3rd St in Columbus, Montana.

    This layout can work well for tenants or owner-operators who want multiple independently accessed living spaces within a single building. With separate entries and full kitchens across the units, the configuration is suited for residents seeking privacy, as well as for operators considering a short-term rental use for one of the main-level units, as described in the remarks. The combination of in-unit kitchen functionality and on-site laundry access helps streamline day-to-day living for occupants.
