Description

Excellent investment opportunity or owner-occupant option in the heart of Janesville! This side-by-side duplex offers two spacious 3-bedroom, 1-bath units, each with private basement access and separate living spaces. One unit is currently vacant, providing flexibility for an owner-occupant or the opportunity to place your own tenant and maximize returns. Recent updates include brand-new lower-level flooring in the 423 unit, while the 425 unit was refreshed with new paint and flooring in 2024. A large off-street parking area behind the building provides ample parking for tenants and guests. Previously, both units rented for $1,500 per month when fully occupied, making this a strong addition to any investment portfolio.
