Investment Insights

Based on property information with market context.

This side-by-side duplex contains two four-bedroom units, each with a full bath and a walk-out basement. Shared enclosed front and rear porches serve both sides, while separate meters support individually managed utilities through Boonville Municipal Power. The owner's unit adds a finished attic with approximately 800 sq ft of space, including two bonus rooms, plus 800 sq ft of unfinished attic area. Smart switches and programmable thermostats are installed throughout that unit, and most windows have been replaced with thermal units.

A fully fenced backyard and an oversized 4-car garage expand the property's practical utility. The garage includes loft storage and was enlarged approximately 10 years ago. Other notable work includes a full roof replacement and a rebuilt front porch completed 4 years ago. The property has been owner-occupied, with one side used as a private in-law suite, and the layout supports either continued owner use or occupancy of both units. It is zoned Residential 2 Unit and was built in 1910.
