Incredible investment opportunity in the growing community of Oronoco, MN. This well-maintained triplex has been owned by the same landlord for over 20 years and is now primed for increased rental income and long-term value. The property includes three separate units: a spacious 4-bedroom, 2-bath main unit spanning 2,000 sq. ft. across the main and second floors; a 2-bedroom, 1-bath basement unit with 800 sq. ft.; and a 600 sq. ft. efficiency unit with 1 bath on the third floor.
Current rents are below market, with Unit A vacant, Unit B renting at $850/month, and Unit C at $750/month. Market rent projections show strong upside, with potential to achieve $1,900 for Unit A, $950 for Unit B, and $850 for Unit C.
Each unit is separately metered for gas and electric, and tenants are responsible for their own utilities, including internet. The owner currently covers water, sewer, and trash. Shared laundry is available in the basement, and there is a separate meter for both the mechanical room and laundry area. The property features a dual heating setup with both a boiler system and furnace as well as updated vinyl windows and metal siding and a new roof in 2017.
Recent updates include a new water heater within the past five years. The property has also recently been connected to city sewer and water—an essential infrastructure upgrade that supports continued growth in Oronoco.
This is a great opportunity for an owner-occupant to live in one unit while generating income from the others. It also makes for a smart first investment or a strong addition to an existing rental portfolio. With solid bones, recent improvements, and significant rent growth potential, this triplex offers excellent value-add potential. Implementation of a RUBS (Ratio Utility Billing System) could further optimize returns. Don’t miss your chance to invest in a cash-flowing asset in a rapidly developing area.
