Overview

This side-by-side duplex includes two separate 3-bedroom, 1-bath units, each with its own private basement access and distinct living space. Unit 423 is currently vacant, creating flexibility for an owner-occupant or a new tenant. Unit 425 was refreshed in 2024 with new paint and flooring. Additional recent updates include brand-new lower-level flooring in the 423 unit. The layout supports comfortable, separate household living while maintaining the efficiency of a duplex configuration.

The property is located in the heart of Janesville and is served by a large off-street parking area behind the building, which can accommodate tenants and guests. That convenient on-site parking helps reduce reliance on street parking and supports everyday access.

For tenants, the combination of private basement access and fully separate units can support privacy and straightforward move-in transitions. For owner-occupants or investors, the current vacancy in Unit 423 allows you to set up the living arrangement on one side while maintaining a second unit for rental income potential. Recent interior updates across both units can help streamline leasing and turnover planning.
